Well here she is... after 2 months of waiting from placing that call into AB from TN the new Losi is on the workbench and ready to get built!


Now, I must say I am very impressed with this rig. The packaging is top notch, and it is all the details that set this kit apart from the rest. This is a comp roller so it is pre-built but the packaging holds it well. The manual is very clear and well thought out, not to mention actually has a nice glossy thick cover, and fold out set up sheet(s). The body is pre-cut and holes for the posts are pre-drilled for you. The servo mounts, tool kit, and 2 yes 2 AL servo horns are included. The horns fit Hitec and JR servos, and this is a nice touch right there!

Fit and finish seem great, but being the tinkerer that I am, starting tomorrow I am going to tear it down and rebuild it. Just like I would do any race ready roller.


Check out the axle clearance! My Axial with Comp Claws is sub 2 inches, the Losi on reg Claws is almost 2.25 inches!!!


On to the Losi p0rn....

Stay tuned as I go through the Losi there will be a ton of pics!


Set-up so far will be as follows:

Mamba Max
CCBEC
Hitec 5995 for Steering
Losi MRC Steering Servo for Dig
Thunder Power 1320 mah 3S lipo
Motor.....

This is be one of the following: Stock 27T, Reedy 17T single, Integy 35T rock crawler, or Kyosho Mag Mayhem

It really is, once you see it in person. Everything is laid out very well, and in about the most compact way possible. Not to mention this rig is LIGHT!

I will get some more as I do the tear down tonight, any request of what you want to see or just general close ups?

I will also go through the steps needed to break in the worm gears as I do this tonight.

For now I will, as it is a very nice and super lightweight chassis. Down the road I may coinsider modifing my old chassis design and having a new one cut. Right now though, I don't think I need to worry about the chassis.




The key point here, as with any worm gear truck is picking the right motor combination. Once I get that sorted out things will really start to fall in place.

Getting new toys is fun!:rkn:

I should have waited another month to get back into crawling!

I would think that the chassis is pretty much comp ready with all the adjustability that I can see.

Only reason to change it would be for sponsorship or just for bragging.

Can't wait to see this rig lay the smackdown on the cheater rigs!:Urck:

It's fun, but at the same time it takes a lot of commiment to sink my points series on something new too :confused0068:

I still think you are better off with your set-up. This truck is going to take some time to really dial in and get working right. It's not for the faint of heart, just yet.


The chassis is pretty good for being able to tweak your set-up. Which is why I have no interest at this time to change it.

In time it will, I wouldn't expect much right away. I have to figure out the motor combo, get it fully broken in, and learn how to drive it to its limits like I can my Axial truck. Once that happens, it may surprise a few people with what it can do :tmbup:







You're asking a lot of this rig...

Who me? :lol: and what rig of mine don't I ask a lot of?????

Yes it will, but I think it will be as good as my Axial in the end, if not better.

Thanks buddy, there will be more to come tonight, Friday, Sat, and Sun will be the real test. I'm just going to ease into things are get it ready to rock and roll on Sunday. That will be the true test of playing following the Berg :twisted:

I do understand what you mean about changing rigs in midstream...that was one of my problems when I competed before. Too many changes and didn't take the time to learn to drive each version.

I like my current setup and swore to my self that I would only tweak it as needed...no major overhauls!

Is your Axial going to get dismantled for parts?

Maybe you can use it at comps that you feel you aren't ready to do with the Losi just yet.

You've got the experience...I'm sure you will have this new rig dialed in in no time.:tmbup:

This is true, but THE berg never comes out to play any more. This berg I will be following Sunday is pretty good too. Now if THE berg wants to play then bring it :wave:

:shh:


You are getting ahead of me here :dunno: But yes, not going to full lock is one of the tricks to keep the CVDs alive at this point. Due to the design, and use of plastic C's and Knuckles if you go to full hard lock on the steering, you can flex past that point and break the CVD. I will get pics of this up later...

It's a huge change midstream, but I feel what I can gain is worth it.

I haven't touched the Axial set-up in almost a year. Never did much other than play with weights, and tires/foams on it. It is full on dialed at the moment.

Possibly or it maybe sold as ARTR to someone, or I may keep it.... i dunno yet.

I thought about that, running the Axial and letting the Losi sit at comps, but in the end you aren't gaining anything. In order to get the rig dialed and used to driving it you have to do it in comps. Practice runs are never the same as a comp. Besides doing that is too much of a crutch and an excuse to delay getting the Losi dailed in.

Thanks man! IF my tricks that I will share as I do them to the rig work, and IF I get the motor nailed quickly I would suspect that this rig will keep me in the hunt and I won't be loosing too much ground in the series.




There are a few things that must be done right away, but after that it is just personal taste. So, I know there are a few guys over on RCC that have gone out and played Berg vs Losi so far. If you take your time setting the Losi up and minding the details, from what I am hearing the Losi's are flat out handing it to the Bergs.


But, we shall see... if I can get it up and running and dialed in fast enough to do well next Sunday :drv:

I found a cool place under the Apollo bridge...25 minute drive from Monroeville.

Probably ok for a small GTG, but maybe not a comp...although I could see running two 2.2 courses there.

so what other tricks you got cooking up for the truck?

Bustedcrawler
06-04-2009, 06:49 PM
Well let's start by digging into the axles....


We get AL hexes, which is nice, CVDs, king pins that have a set screw that comes in from the side... much better than bolts that pretend to be king pins, AL steer links, and a nice clean housing.


A few key tips here!


1) Check to make sure you only have 1x shim per side on the spool (spur gear) as most of the kits have had 2x per side and this adds extra stress

2) Use some tooth paste or polishing compound, plus a drill to break in the axles

3) Clean and then regrease the poo outta the axles. Worms are inefficient by nature so lube is your friend

4) Heat shrink over CVD pin, and lube the CVDs. One of mine was a little stiff



On to the pics!

I gots a few buddy. Mainly break in on the axles, lubing and reassbly of the trans, and motors I will try.


This rig is super light weight and using only a 540ish can motor means more ground clearance with a low CG.

Ok, so I messed up and didn't take my own advice and lost a Driveshaft pin. Oops... that is what I get for trying to use a dremel and not a drill for break in.

However, a silver B44 swaybar is the same thickness!


Well time to clean out and regrease the front and then put it together!

Just a quick question. How does the worm gear setup compare to a esc with adjustable drag brake?

Bustedcrawler

As far as...... braking? There is no comparison.

Drag brake is like having 4 wheel disc brakes, with 2 pot calipers and organic pads. You'll stop sure, but thats it.


Worm gear is like 6 pot Brembo's with carbon pads and rotors. You will stop and if you are not careful flip the rig or at least get light :tmbup:

Bustedcrawler
06-04-2009, 10:24 PM
OK axles are greased and put back in. Will do some breaking in later on.

Rebuilt the shocks with 40wt for now, to help slow down the action.


Now getting into things to install a motor we find something very familar... the motor mount is similar to that on the TC3. This still is very nice to have on this truck as you can get to the motor and adjust the pinion with only 2 screws! Very cool Losi!


On to some more pics...

Bustedcrawler
06-05-2009, 12:51 PM
A big thank you must go out to Rich at Losi! A very stand up guy and is making sure I get spare shafts went to me in time for the comp next week!



It is also to be noted that the extra shims were of the correct 0.20mm thickness as called out in the manual. I'd imagine they are shipped in some sort of cosmoline or oil and they stick together, so that makes it easy to grab 2 and not 1.



Well, after I eat lunch more trans pics and info to come!

Bustedcrawler
06-06-2009, 07:47 PM

Umm, need a BEC if anyone has one. I started to rush and had the esc wires reversed to the batt... took out the BEC as plug in smoke then unplug. I hate rushing lol :cry::rnt::rnt:

Bustedcrawler
06-07-2009, 11:42 AM
Well I now have it up and running. Heading off to a secret test spot here shortly to see how she does.


1 big thing to remember kiddies... the motor pinion needs to be 48 pitch! So I need to go get a few first.


Then a 24 deg timing 27T motor, while is has awesome wheelspeed, will let out the magic smoke if you try to do anything other than flat ground.

Sooo out with the 7T from the Axial and in it goes to the Losi :confused0068: I hear good things on this.....


Will report back with pics!

They are something else for being out of the box. I would have gone out there, but I can still barely walk around much less try and being on those rocks at the moment.

Well, I got everything buttoned up but the paint and body work. Didn't quite have a decent 540 motor to run, soo the 7T puller got called into action :confused0068:


Ran from 12:30 to 3:30 and this thing is very nice! Got the gearing sorted out, and now its just time for the gears to fully break in. No issues with the CVDs, only real problem I had was the slipper right out of the box as it was loose. Got it set up to where I like it... it will just slip if I try and get stupid :tmbup:

Steering is amazing, and the dig is by far and away the smoothest mechanical dig out there. I couldnt get to bind no matter how I tried. All it needs now is a little shock tuning and its set for Sunday.


All I will say, is there were some lines the Axial wouldn't do that the Losi did with ease, and there were a couple of lines I know the Bergs and I were trying to get but I cant remember if anyone did :hmmm: that the Losi walked :twisted:

I'd say right now its on par with my Axial, give me a few months and this rig should be dialed:bow:

Running a Holmes 35T an FX-R and 3 cell Lipo with 14T pinion.. If you guys remember gate #2 at the last comp, only a couple of guys made it right up with no problems... well this thing walk right up it at a few angles, made it every time!

Good deal, I know the puller gets a little warm after 15 to 20 minutes of running, so I am looking for options. I am planning on trying a 35T to see what it can do. But, for now the Puller will work, just kills the batts between the worms and the puller.

Hmm.... hadn't seen that post yet. I've been reading the Losi section since it started :lol:

Looks like I have 2 more motors to by and try out now... 21T Titan and a 35T handwound.

With the puller I was expecting it to heat up as even in my Axial I could get it warm to hot. So with the worms I was just planning on it :crzy:


May have to swing by the LHS and snatch one of those Traxxas motors up to see what it can do and give it a whirl, as I have a 15T on the puller and its nice! 16T is even faster, but the puller warms up a little quicker than I'd like.

Mamba stays around 100 after I'm done, puller was 150-170 ish, and axles were just warm and not hot. Gotta love Rocksmith GearJelly :tmbup:

Got the body masked up and ready for paint. Just need to convert over to velcro body mounts and that part will be done. I forgot how much side mounts can bug you, until sunday running it and hung them up. I'm so used to the smooth sides of vecro these days having body post sticking out threw me for a loop :lol:

I will pick up a 21T Titan later on this week and get it installed and tested. Hopefully it will run cooler than the Puller, but I will also be installing a fan above the motor. The Mamba seemed cool enough, but it may get one too if needed :tmbup:



During testing I found that this rig likes a lighter wheel weight set-up so I am down to 2 slugs per front for a total of approx 2 oz of weight on top of the AL wheels, from the orginal 3 slugs or approx 3 oz. I will be keeping the extra slugs with me as I may try them again and see. I got some slightlu better results with 2 versus 3, but then again the rocks I was on were dusty and my tires where still covered in dust and dirt from the last run.

Just finished up the go over.. lubed, greased, shims removed, etc.... Installed the Titan 21T with a 14T pinion. FX-R and a 3s Pack (1350).. Well after 8 min of abuse in the rocks and grass the motor reached a WHOPPING 187 DEG.!!! OUCH no touchy touchy!!! The wheel speed was nice and had just a little bit of stall, i'm going to put the Holmes 35T w/14T pinion and do another test. I'll post the results a bit later..

Ok.. just installed the Holmes motor (w/14T pinion) and ran in hard for 10 min., No noticeable stall and still pretty good wheel speed. The motor was at 169deg. Ft axle 173 deg. Rear axle 110 deg... Big difference between the axles, they felt super smooth upon reassembling them.. I think i'm going to try grease instead of the lube..


Hmmm, interesting about the Titan. I know I was running 15 min-ish and only getting around 170ish. Hot to the touch but can leave your finger on. I really need a temp gun :o

I know my axles weren't that warm.... try the GearJelly man it flat out works!!

Made a few more changes, swapped over my old Losi's from the Axial as these kit ones like to leak. No biggie to me, as I wanted the 60wt due to the 40wt being far to light and thin; and the 0.25" internal limiters. Got to be able to float a tire :shh:

Also did up the body so here are a few of the finished pics... strike that finished body work pics :mrgreen:

Sometimes I hate the fact I see 1 thing I want on a body then make everything else work:yikes:. Sadly I bought the XXXMain sticker kit for a MGT/LST sized truck for the chicks, then had to work in the stars which meant using blue.... all for some chick :gum:

It's the answer to all of our problems... :bow::roll:

Now what fun is it going to be if everyone has a LCC??

I guess I have to go out and buy one to be competitive... but I have a thought...:hmmm:


So did ya buy one yet??? :lol::lol:

I'm looking forward to putting it next to the RockForce and comparing the two rigs. I know yours is pretty well dialed in so hopefully I can get mine there quick.



It's a fun truck, but honestly, with the motor games you have to play and different driving style... I would say 90% of guys looking for their first comp rig would be a lot less stressed out and happier with either Axial or Berg.. Oh wait Berg is disco'ed from what I am hearing :shh:

As I said before this truck is not for the faint of heart. It is a whole new world of driving, that given my old truck's set-up I was sort of familar with. It's good out of the box, but it needs tuning to be great.

It is a Comp Roller aka Race Roller not a basher/comp rig. Hence why I don't understand these guys looking for ways to run 4 hrs non-stop :hmmm:



Stick with the RockForce and hurry up and run Pro with us, then we can have some fun :tmbup:

All that is left is a little wiring clean up, which I will do later when I give the super the same treatment.



Got the velcro body mounts whipped up and installed last night, so that is good to go :tmbup: as side posts just hang up too me for my taste.

Did a little messing around with the Mamba settings to try and help out the heat issues. So we will see...

Also, got my new CVDs in. They are of the "new" design, basically Losi corrected a machining error that was missed. The slot for the cross pin was cut too deep and was in the neck down used for clearance on the stub axle cup. That made for a HUGE stress concentration area and riser so it was easy to break there. So this means I can take the EPAs from 85% up to 95-100% now :tmbup:

All in all I say she is ready for the comp tomorrow.



Working on a motor lead that maybe a good answer, but this Cat is staying in the bag until I try it out :gum:

Time to bring this thread back on topic here.... :crzy:


Picked up a few more things for the Losi today. 1 more battery for it as it is a battery hog, a Venom on board Temp gauge to keep an eye on the motor temps, and a Traxxas Velineon Cooling fan to help keep that motor cool.

This will now make a clean electrical install tough, but I will add pics once I trim the body as it is in the way of the Comp Claws, and get all of the new and old electronics wired and installed nice and neat.


The temp gauge will be readable through the windows in the body and the fan will be positioned so that it is pushing air through the open endbell of the Puller. Hopefully, this plus the programming change will help lower temps. If not, I have a 14T pinion to try out also :tmbup:

No cleaner way to mount a body than velcro stand offs and velcro on the inside of the body. No post on the side or top to hang up on, and I use enough velcro that the body will bow and flex before it comes off in normal use, but is still very easy to remove the body :tmbup:

So after all the problems I had today at the comp, I came home and installed the lastest version of Castle Link and started to update the Mambas.


One of the cool features I found in Mamba Firmware 1.21(beta) is that they have added punch control. Unfortunately start power and timing is no fixed, but Punch Control will be great for Losi's and Rock Forces.


Punch will let the motor slowly spin down instead of coming to a fast stop. This will help prevent worm geared rigs from endo'ing when you let off the throttle.

Doesn't surprise me, honestly as I saw wear after 15 mins but that was just taking off the coating on the worm and spur. Have they on this other site, defined "significant" wear???

As this is a new rig, what is coinsidered "acceptable" wear? :hmmm:

Not bad, guess I need to place an order :)






:wow: that sucks! But as with anything in the crawler world its going to wear! Would be nice to get more than 3 comps on it before that starts to happen though! Hopefully some after market gears will come out with stronger metals and longer lifespans.



Nothing against you buddy as you are trying to help, you just happened to be the last person to suggest this and it is a pet pevee of mine... Stronger Metals does NOT equal a Better Part ALL the time.

Yes it is china made stuff, yes there maybe "stronger materials" but without knowing WHAT the gears are made of, and WHAT the Heat treat process was and HOW were they machined... this is all grasping at straws. But, I will more than likely send a pair off for cryo treat as I can get it done for free :tmbup:


My R2D showed wear after 3 comps, as did my axial R&Ps, and my TLT R&Ps, and my TXT gears. Even brand new ones that I had just installed. Does this mean Tamyia and Axial screwed the pooch too?


It is called break in, the wear for the first 10-100ish hours of service, depending on how the engineering was done, is some of the most severe as parts create a wear pattern, work harden, and match each other.

See here is the problem, a stronger metal with the wear pattern they have will net the same result: Premature wear and short life cycles. As the contact pattern (and therefore wear pattern) dictates the forces and fatigue loading on the material. Incorrect pattern = higher loads = faster wear.

Material is only a small part of the design process, and it comes at the end. Not only do you have to pick the right base material, but you have to pick the right heat or cryo treat process for the application to apply to the base material also.

Not to mention the biggest misconception I have seen on here and on this other site is in how worms work. They do not work like bevel gears or straight cuts or helicals. The standards trans, transaxle, and axle gears that we see work by the teeth pushing on one another rotating the gears. The teeth rotate against each other and there is minimal sliding of the teeth on each other. Worms are very very different. The worm gear more or less SLIDES on the spur forcing it to turn. As the single toothed worm rotates it pushes into the spur and then slides across it causing motion and engery to transfered. This is part of why they are so inefficent, and part of why not matter the material if you don't have a good wear pattern, good thrust bearings on the worm, and a good heat treat they will all live a premature length life compared to an identical worm gear set with the correct material, the correct contact pattern, the correct heat treat, and the correct thrust bearings on the worm.


Designing worm drives is harder than a standard R&P design to do correctly. Not to mention it takes a different type of bearing to support the worm than I have seen in either worm gear truck. Only 1 worm drive truck had the correct bearing on the worm, and it was a full tilt, machined in his basement, custom crawler.


I would like to see what the numbers on comparing a new versus "worn out", and who is posting. There is a lot of "angry with Losi" bashing going on because there are normal issues with a new release that are being compounded by the hype, the newbies with no techinical or crawling background, and just general why isn't this the answer types of folks.




Same thing with the CVDs... everyone attacked poor Rich and Losi over needing better materials. Guess what a machined slot that was done too deep was the root cause of the premature CVD failure. We really needed stronger metals there too huh? The way that was machined a stronger metal would have only gotten you a little further before failure and not prevented it :tmbup: Sometimes looking at the machining and engineering is better than the material side of things. :tmbup:



The chicken little is strong with a lot of Losi owners and with those following it :gum:

OK... got everything sorted out and rewired. However, in rewiring it the cheapo wire that Traxxas used on the fan broke off of the fan's board, so I didn't have a cooling fan for the duration of the run :shock:

Took it out for a spin with Lewis today. Ran through 3 battery packs.

Run time is around 30ish minutes. Give take some here.

Motor temps, 15T pinion and 7T puller... max was 164. I love having a temp gauge on board, as there is no more guessing or lag time to see max or current temp :rkn:.
I may try a 14T pinion to get some more bottom end out of the motor and see if temps go down. Wheelspeed with the 15T is on par with my old Axial, 16T was wicked fast but motor temps got hot fast, so I am hoping a 14T will cool off the motor just a pinch without loosing too much wheelspeed.


Handling... WOW, just WOW! This rig is just perfect for me and my driving style :mrgreen: Did all the same old lines up at AIDS that the Axial did (most were done easier too), then a bunch of new ones, and even 2 lines Lewis' Berg couldn't do even with playing around on them for 5 to 15 minutes :gum:!

Dig worked every time no fuss and no muss. Rear dig is GREAT! Really helped me do a few lines that I don't think the Axial could have done. Not to mention having my steering set to 95% is awesome! I could steer through lines that Lewis' Berg needed a small dig action to do :shock:.



The bad... Slipper needs tightened a bit more. Not much hut just a pinch, it is kind of nice knowing I have one to keep from blowing things up. It is just a bit more to think about as with the old Axial I would make it or break it :yikes:

Loctite and shrink wrap is your friend on the Driveshaft pins. I had one in the rear drop out :rnt: and thankfully we found it and got things put back together :tmbup: and kept on crawling.



All I can say is for me personally, this rig is great! Some more tuning and it will be dialed!

OK... update time


Ran it again today, Lewis and I ventured up north to visit Mystic and run in the fishbowl aka J&C Hobbies in the Mills, where Coles' old tables are set up by the window for all to see :drv:


We really need to do a GTG up there as it would be a new level of pressure with the crowd watching :dude:


Anyways...


puller spiked to 186 deg :wow: with both the 15T and the 14T pinions. Wheel speed was still good on the 14T but it had enough torque to bump the slipper a fair bit more than the 15T. Tightened it up some more and we will see... may go back to the 15T.

To keep temps down, I scored an Integy heatsink and fan from Dad's World of Hobbies. To get it to fit, I had to take off 4 rows of fins and then cut out the 2 sections closest to the dig. Talk about 50 lbs of crap in a 5 lb bag :wow:. Flipped the fan over so it blows air down through the endbell of the puller. We shall see how this works tomorrow....

To help out moving weight down and forward, I took off the stock battery try and with the help of my good buddy Dremel, made a few holes, cut off the lugs to mount it and BAM! instant link mount battery tray. I did this over a piece of lexan as the stock piece has 3 sides to help hold in the battery and is pre-slotted for use with velcro. Seems it gets close to the driveshaft, but I should be ok... we shall see tomorrow.

One last trick, I pulled from that other site, is on the lower links I took 3 shock o-rings and placed them on the sides and in between the lower link rod ends. Seems the ball is slightly smaller than required and they can pop off the rod end under severe use. Not a big deal to me, but a trick to keep in mind.

Pulled the trans apart and checked everything out, as every now and again I get a slight click but it goes away. Not sure if the skid is flexing and allowing the motor plate to move or if it the worms coming out of sync :dunno:. Never happens long enough for me to trace it, soooo for now I'm just going to keep crawling :drv:

Spur gear went right after we got to Yorkville :rnt::rnt: thankfully ya'll had some in stock that I could get, but still meant I wasted a day. Oh well....

No problem man!

That is a bummer to hear. I know mine was sheared off and not melted, so I will see what happens with the new pinion once I pick it up.

Not sure why it would get hot if mesh is right, unless the motor is sending that much heat into the pinion...

That is the difference, an Axial uses the trans for a lot of the reduction, and the motor isn't trying to turn the same RPMs as it does in the Losi. The worms are the Losi's advantage and downfall.

While the final drive ration maybe close between the two, if you look at the reduction at the trans the Axial will be much higher. The Losi trans is more than likely even lower than a racing trans which are in the 2.6ish range. This means that the motor is turning very high RPMs, and the worms are a 25:1 ratio so every 25 turns of the pinion you get 1 rotation out of the spool. This constant high RPM use creates heat and a lot of it.

I think that is part of why brushless is a popular solution, as they like being in the 150ish deg temps, and they tend to turn a lot of RPMs.




try the 21 titan


That or if you have a Trinity Monster Maxx motor you could try that after setting the timing to 0-10 degs.

Right, with this truck it is all about testing and tuning to find that perfect combo. Part of why I state it isn't the right choice for most beginners as it does take a lot of work to get set-up. After that, all is well :dude:


Yeah the 21T Titan will work for a while and then let out the magic smoke. Then again for $20 is it that bad if the magic smoke comes out?

Time for a bit of an update as the rig has gone through a few changes since the last time I posted in this thread.

First, I grabbed up all the AL axle goodies from Losi, so it now has AL Knuckles, Straight Axle Adapters, and C's. Also put in the TI Nitride kingpins and tie rod bushings. Also, picked up a pair of the V3 CVDs and slapped them into while I was in there.

I had a set of bad worms, so a quick email, and Rich T had a set out to me. Got those in and relubed with some more Gear Jelly and all seems to be well in the world so far.

THe old Hitec servo was getting old and not always turning when I wanted it too.... not cool in my book so out it went and in went a JR8711 in its place. I heart 403 oz-in of steering. :tmbup:

Then the comp claws were smoked after La Guerrra, and have gone down hill since, so off they went and on went some white compound Rovers. For out here they can't be beat. Threw in some ProLine Dual Stage over sized foams and called it done! Even in the freezing cold....well it was technically below freezing, at the Halloween night comp they didn't go completely rock hard like a true memory foam only would. :D

I had made some more suspension tweaks as I fine tune it and a few weight tweaks up front too to help it out.:drv:

But one of the bigger changes was the addition of a Novak The Goat 3S and a Crawler 21.5T brushless motor.:dude: I had plenty of wheelspeed, but still wanted more. Had more than occasion crop up at comps out here where I needed that little bit extra and didnt have it. So in went the 21.5T and a the new Goat 3S as I can't/won't use anything less than a 3S anymore. Given that Rubbaneck uses Losi's 21.5T on a 3S and is the Losi to beat (which I have done a course level not quite a comp level yet) I figured he might be on to something.


Can't complain as the last comp I went too, I kindly upset the locals as the OSFNG placed 5th and went into the finals at his first comp. Ooops :dude: Stayed in 5th as all of us in the shootout made it to the same gate and then pointed out.

We will see how the Goat does come Sat in the next Comp, and then next Sun at the next CO RCC comp. Yes I am running in 2 series out here :drv: gotta love it!!

Well if ya'll need any more info or have questions just shoot!

If you have problems with the memory foams getting stiff in the cold, pick up a set of Novas Ark's 2-stage foams. I put a set of them in my medium compount Rovers before the last comp, and my little tuber was unstoppable. I've never done much with foams before, but I'm now a believer. Also, they're not a memory foam, so no change in performance at low temps.

Well got the Losi out tonight for some crawling over at another RCC member's house... lights, rocks, tunes, and beer... hard to beat!

The Goat 3S with a 21.5T and a 14T pinion flat rocks! The truck ran great, and the first course I was within a few points of Rubbaneck so I was pleased. Only downer was running my 2nd course the Rx shutdown and left the truck running outta control :confused0068:. Looks like I need a new Rx before Sat's comp. This new combo has tons of low end control but a boat load of wheelspeed if i need it! Although I must say I already found its limit and had the truck so bound up that the motor just refused to turn and made funny brushless noises, but it was still cold to the touch.

The more I drive the more I really like the Rover and oversized dual stage Proline foams set-up. Just soft enough to wrinkle and grab traction, but still firm enough to be stable in the sidehills and to not wad up when you dig.

The truck is really dialed now and coming into its own, and I am finally hitting the sweet spot with driving it.


Last thing to do is outboard the rear shocks, but so far haven't really seen the need as the other Losi's I run with that have done that still flop over in the same spots I have.

Bustedcrawler
11-05-2009, 01:02 PM
Well after digging into the Rx shutdown issue, I found the Rx to be ok and it was the CCBEC that crapped the bed on me :o

Well pulled the super's CCBEC out and put it in the Losi as I have a comp on Sat for 2.2s and 1.9s... we keep claiming that supers will run but I havent seen it yet. So when I get up to HobbyTown for the comp I'll grab another CCBEC for the super as next Sun is the big RCC comp.

MASCMAN

Glad the set up is working for you as I'm going the same way.

What ype of battery do you run and what kind of run time?

I don't have the Goat 3s yet, but I'm guessing the BEC is not good enough for comp trucks?

Isn't it an external BEC that I could possibly use on my Scaler...allowing me to steal the Castle from it?

Bustedcrawler
11-05-2009, 05:19 PM
So far so good. Seems to be also a bunch of guys running the Goat 3S and a 18.5T motor, and a few using the crawler 13.5T motor too.

Still using the same old Thunder Power 1350 maH 3S lipos, and I couldn't tell you what run times are. All I do with my Losi is comps and comp style practice. Basically running through gates with a timer going, so I just run mine in 5 minute or less segments. It's been a long time since I just ran the truck without gates set-up, so sorry I'm not much help here. As long as I can get 5 to 10 minutes of run time I am very happy.

I've heard on RCC with that esc and motor combo with a 3S 1700 maH pack guys are getting about 1.5hr of run time.


The Goats external BEC is a 6V/5A so its worthless for a comp truck with a big power hungry servo, like my 8711. If you are running a lower end high torque servo you might be ok. But, for a scaler I don't see it being a bad choice... but still for the money its hard to beat the 3-10V/10A of the CCBEC. I say swap them and see, then go from there.

MASCMAN
11-05-2009, 05:31 PM
Airtonics 94780 High Torque Servo (423 in-oz at 6v)...will definitely swap the Castle over!

I have the CKRC 3s lipo and don't think I've ever drained it on my Axial with the Puller 500 / Mamba max combo so I hope to be ok with it onthe Losi.

Thanks for all the info!
:rkn:

Bustedcrawler
11-05-2009, 05:35 PM
Yeah definitely swap the CCBEC over, and watch the case of that servo, as they are known to crack.

You should be fine, since you were running the baby pullers on your old truck. Remember brushless is far more efficient than brushed, so you will have better run times because of that.

Just make sure you gear it so that you don't exceed 160 deg F on the motor. Beyond that will cause premature motor failure. Brushless is not nearly as forgiving as the brushed motors are when it comes to overheating.

11-05-2009, 06:04 PM
Regarding runtimes, remember that your motor will be running harder to get less performance, so you may see a decrease in battery life.

Huh? The motor is turning more RPMs but not always working harder. But I can see what you are saying... However I think it balances out with the improved efficiency of the brushless.

Well another weekend down another comp in. Sparky and Rubba got replaced by Neil and Almighty Malicah.. whatever that Berg driving fools name is :hmmm:. Once again tough courses abounded, and the turntable of death made an appearance along with a cable bridge... wasn't cool come off the turntable then make a 90 deg turn onto the bridge.

When it was all said and done I was in 3rd headed into the finals. Over the course of the day 3 Bergs broke shafts, including Jason's 300M shaft :confused0068: which was the pin and not the actual shaft. Too bad the press-fit is soo tight that you have to very carefully machine the pin out and then press a new one in.

After a tough finals course, where only 1 person finished, and the rest of us stalled out at the same spot I was still in 3rd for the day. Must say I made a newbie mistake during the finals course and should have eaten a gate to keep going and finish versus going clean through. Had to want to eat a gate when you are at a 5 going into gate 6 out of 8 gates on a final course :confused0068:




I must say after the abuse I put that Novak set-up through I am very pleased and impressed. At one point on the finals course coming through the pit of death I had the right front tire wedged between the rock and the shock so hard and the rear end bound up tight enough that you could hear the motor ping as it would stall out. Luckily though with some trigger work and some luck the truck pulled through, even though we were all waiting for the magic smoke to come pouring out, but never did. Also motor temps after that run, which ended in a lot of full throttle assaults on the final climb, were in the 130s.

The throttle response is different than what I am used to but I am getting used to it very quickly. I like the low end control and having the ability to quickly get up to full tilt. On one course I was able to just feather the throttle and not using much throttle walk up a pretty nasty climb that was eating a lot of trucks alive both berg, and losi and even the token bully had issues with it.


All I have is the one pic of the truck dropping into the hole of death.


So we well see how it stacks up at Palmer on Sunday for the RCC comp.

Well, put the Goat through the ringer again yesterday during a brutal practice session with the Almighty... and I got schooled by that kid too!

Truck is working great and now its down to just me driving it better.

Once again, I am really impressed with this Goat system, as once again I was running it with no mercy what so ever. After one course the JR servo was sitting around 145 deg and begging for mercy and the motor on the goat hit 160ishl, but after about 10 or so minutes it was nice and cool again :tmbup:.

This system really is nice with how it can go from super slow finesse crawling to getting it and then back again.


Still trying to sort out a rough run time, which I should be able to do tomorrow during another practice session with Big Tex and TMYJeeper aka Tim McGee the photographer from Crawl. Maybe I can finally get some GREAT pics of my truck :p

Then Comp on Sat, followed up the with RCC comp Sun, with comps the following Fri and Sat. The trucks are getting beat up pretty good, and still asking for more.


The Rovers are slowly starting to really come in, as most of the guys say they arent broken in until they are smoked. My combo of white Rovers and the over sized ProLine dual stage foams is working pretty nicely so far. Foams are firm enough to give really good support but they are still soft enough to let the tires wad up when you need them too.


I'm thinking the tweaks are done with this rig for awhile as I learn how to drive it better. It's capable enough to hang with the big dogs, so I just need to up my driving.

Bustedcrawler
11-14-2009, 10:37 PM
Well lets see.... ran Thursday and was taken to school by Tim McGee... his picture is in the dictionary under smooth. Dude has made skills... for those who have seen his build thread and watched his video, let's just say that last climb into the gap jump is deceivingly easy when you watch him do it. Took me the better part of 20 mins to pull that line.

But anyways...

Truck is still going strong, although at today's comp it wasn't my day. Got c0cky trying to clean things instead of taking the safe, guaranteed line, had some issues with the motor stalling out again or binding things up and needing a reverse, and just wasn't my turn to be on top. But still a good day of crawling, even with the light flurries we were crawling in:yikes:. However, in talking with a few other guys I have a Y-harness waiting for me to pick up tomorrow to change how the BEC is wired into the truck. This should free up a little more oomph to keep that motor happy.

Basically the ESC will get max power to it, and the BEC only feeds the servos. This should help eliminate the random glitching I have had too. Seems I am getting the motor to draw soo many amps the BEC fads just enough to shut down the RX.

The Dynomite Servo arm I had stripped out, as in the bolt holding the draglink on pulled out of the servo arm, even though I used a liberal amount of locktite on it. Odd, but oh well.

Rovers are starting to wear in nicely. May look into Nova's foams, but even though my ProLines got firm in the low 30s we had today, I had no real big loss of control anywhere. Still was able to wad them up nicely at times.

Bustedcrawler
11-16-2009, 02:04 PM
made one small change on sunday at the indoor comp. changed how my BEC is wired, and WOW what a difference that made. No more stalling out with the motor, no more Rx shutting down and a pinch more wheelspeed. servo seems a pinch faster too.

Well either the V3s arent what they are cracked up to be or I'm just that hard on my rig as I broke a V3 last sunday :confused0068:. Now in it's defense it did shear after a 40ft tumble down a rock face that we were playing on. I need to get pics of the line, as you take a vertical run up, then shimmy the truck sideways, then finish off the climb to the top :rkn:

AMain was the only place I could find them in stock, so had to get some as we were supposed to have 3 comps this weekend and its down to 2 now, and Im not certain on Sunday due to the snowy forecast.

But anyways, the new CVDs are coming and will be installed, in the mean time I took the tranny apart and pulled a few tricks to help it shift better. I was having problems with grinding noises and occasionally it'd pop out of gear on me. The plastic dig locks are nicely worn from shifting under power, so I have extras as I am hoping the new springs will help out.

While Im doing all of this, I am rebuilding the shocks to no longer use the internal limiters. They helped out great for Rip Rap, but hurt me on the natural stuff. SO out they go and on go the external limiters, and with that outboarding the rear shocks. I also have some Losi Grey and Losi Gold Springs coming to try and loosen up the front end a little more.

Well been tinkering with the truck for a while now. Santa was good to me so I got rid of the TP 3S batts and stepped up to a mix of 25C and 35C Hyperion 1300s which are just nice after dealing with the 13C TP batts. Made a huge difference in the truck.

Also slapped a pair of stock wheels on out back, until Wed when my V2 SLWs arrive :rkn:. Also put in some other foams than I had been running too to help save weight and increase traction and stability.

Testing and then a full day of running courses on natural terrain with the stock Losi wheels and new foams has shown that for me I've got a great set-up going with a huge front to rear weight bias. The current balance point is forward of the front edge of the skidplate :tmbup:. Not to mention the super soft foams and tire combo is great too!

Got a new suspension tune that is just sweetness. The rig flat out works, climbs, breakovers, side-hilling, everything is soo much better now with this set-up.

Still need to video some of the stuff we do when we play, just nuts! I know I'm making stuff that most of the other Losi's out here can't, and lines that there are only a few Bergs can do too :confused0068:

Had to swap out the dig plates as the old ones were toast from too many under power digs and that much use.


For those interested, with the DH wheels at all 4 corners, 6 slugs in each wheel up front, the RTR weight was 6 lbs 6oz.

With the Losi wheels, new foams, and everything else the same, the RTR weight is about 5 lbs 8oz; which should drop to 5 lbs 4-6oz with the SLWs.



EDIT: I should say that picture isn't of the truck climbing, but of it coming up through a sidehill bonus line

Well, got a bit of driving in on Sat, had another decent run with another 5th but due to how the drops worked out for the series the unoffical posting showing me 8 points out of 2nd for the series was null and void and I ended up 4th for the series.

Left the DH hubs on the SLWs as there isnt a SLW hub that puts me at that width, either wider or narrower. May try the SLWs hubs and see, as it should just be a pinch wider but not too much. If it is, well, I have access to a lathe now so I can fix that :rkn: The .7s are sweet, rig was as planted as always, only difference is it seemed more sure footed when rear burning after stuffing the rear tire to get up a ledge. Made downs slightly more interesting but not enough to worry, as having the back end so light compared to the front means its hard to go a$$ over tea kettle... BUT when it does want to do that you better be ready for it as it happens fast :confused0068:

Hopefully I can get some testing in out on the natural stuff and see how it does there as that is where the RCC comps are and other big ones out this way.

When does it click? Is it all the tine or just as you're shifting out of dig?

If its all the time check all your pins and set screws for d shafts and cvds.
If its just shifting out of dig.... Then forget about it as that's normal. You cam try stretching the springs but I've not seen a big difference. About every 4-6 months depending on how hard you drive you need to replace the dig plates as they are wear points.

You'll know its time as it'll come out of 4wd and make a racket shifting. That's how mine was after 4 months of hard driving :lol:

Mascman, my drive shafts do click alittle ut i think its mostly just the dig, the driveshafts quieted when i put a lil grease on the yokes were the pins are.


THe comp might be interesting because i'm using a 55t with a 16t pinion :confused0068:
It sucks, really bad. im plannig o getting the 21.5t goat 3s soon tho.




Yeah, the club's grown a bunch since I left so thre are a lot of people that only know me from on here. Well now you know :wave: The 5280 thing is about as common out here for various things as the three rivers stuff is in Pittsburgh.


Yup grease it every so often and you'll be fine :tmbup:


Ouch that will be really rough with the LCC trans vs the LNC trans.

Yeah that is what I have and I've been happy with it :tmbup:

Shouild i try a smaller pinion so i have the torque i need? or just keep the 16t, i have a 14 also that i could put on.

Not sure, as I never ran a 540 sized motor in mine. I had a 7T puller then went 21.5T brushless.


I'd say try the 14T first and see if you need the 16T after.

Well I guess I should throw up another update....

.7s are stupid narrow and normal foam tuning gets thrown out the window. I will be getting some 1s on order (reason to be listed below) but in the mean time I got a set of Panther F400 foams. Yeah that was fun shoving that super wide foam in the rover and on a .7" wide rim :lol:

Made a big difference over 1.5 Rover foams. Truck sidehills better, and climbs a bit better.. needs more wheelspeed, but not horrible. Rear burning is awesome, but its a compromise

.
Truck has a great suspension tune on it now.. super stable climbing, and it rock steady. Doesnt side hill like when I had a set of stock losi wheels out back, but getting closer to it.


Biggest change was having the goat 3S shut down on me... not thermal, but just flip out and forget what it was doing or what it was type crap. Rx was still powered, I have all new 35C and 25C good batts, so I figured ESC was toast. So off on a wild goose chase that worked out and Tues night I found a Mamba Max Pro on ebay and scooped that up. It gets here Fri, put it in... with the Goat 21.5T motor, well to put it politely I've never seen a brushless system cog so bad! Not even sensorless :confused0068:
Digging through everything, found 1 broken sensor wire... patched it back up, and the same result. Tore open the motor only to find my dear old friend, Mr. Burnt Motor Smell :confused0068:, looks like I smoked a Goat 21.5T motor, no obvious discoloration, but the smell was there. I'm also guessing some of the sensors were shoot to in the process.

Well with a "comp" (gtg with money on the line) today, swung by the LHS and got a Ballistic 21.5T Goat motor. Did some field soldering to get the truck running... and WOW is it smooth.

The Goat ESC might be just a RCH smoother right off of neutral, but some tuning with start power and motor timing in the MMPro will fix that right up! Lots of good throttle response and torque, although I could still get the fark squeek I'm stalled out noises from the Ballistic Motor too.

Moved the ESC onto the Rx tray and the Rx on top of the dig servo for now. But I tell you what, its soo nice to throw 6V at the dig servo and using a seperate BEC to throw 7V at the 8711 up front.


So take heed kiddos Novak no longer recommends more than a 2S when using the Goat 3S in a Losi. IT's a big load of BS if you ask me, but whatever. I'm happier with MMPro running my truck as if I need more power of speed, I can go up to a 6S lipo:rkn:

Ok... another brief update...

So far the MMPro with the Novak Ballistic 21.5T Goat is turning out to be a great combo :tmbup: Nice and smooth and plenty of power (for the most part as I can still stall it if I choose too).

Messed around with foam combos in the .7 slws, and found one that worked alright, but I was still suffering on the sidehills. So put a set of 1" slws with a 225 hub on it and the good old stock rover foams. Handles really well, got to watch out and not suck the rear tires under a ledge, as the .7 set-up you could pull up next to it and then bump, not before like with the 1s. But sidehilling is back, and the losi is so light out back even with that soft of a rear tire I can still rear burn with ease. That is one of the keys for me as I tend to do a lot of "shimmy" lines where you are working front and rear dig to shimmy the truck sideways along a ledge. With the .7s you could that with ease, but it suffered in climbing too both flat verts and undercuts.

Seems to be in good shape now. Tore it down to prep for the AWCC qualifer #2 this weekend, and found a broken worm gear. That went in back in late Oct/early Nov. Ooops... :lol: Took one of my spares from the bad spools and put it in. The other "spare" is also chipped so that is out too, so let's see... 2 worms in just over 6 months :lol: Such is life when you drive as hard as I do, and as often as I am. 2-4 comps a month, and 1-3 days a week practice when it's nice out.

For those that haven't seen.... here is the new body I had painted up by Cruzin Illusion over on RCC. If nothing else it'll at least look good :lol:

Sounds like you are getting your money's worth out of this thing!

I have the Tekin Redline 21.5T and can stall it out too with the MMP and 3s...only place I have experience with it is at the Crawlspace and it seems to trap wheels though.

Do they offer different rotors you could swap in for more torque? I was reading that Tekin has one for mine...a 14mm sinterered that will give it more torque and power. I tend to drive more conservatively than you and was surprised that it can stall out as easily as it does...leraned to switch in / out of digs to alleviate it.

Good luck in your qualifiers!:tmbup:

I tend to do that with my stuff :lol:

Places like the crawlspace and two spots out here will do that hard to a motor, but I can stall it out on natural too :confused0068: but then again, with the lines I'm taking it is not a surprise.

I think the ballistic already has the 14mm rotor over the 12mm in the standard goat motor. Its not really that often that I do, just annoying to me that it happens. Oh trust me, I know about the dig trick... I'm on my 2nd set of dig plates as I wore out the 1st. It's looking like I will go through a set about every 4-6 months.

Thanks!

Sally!! :lol:

Look at the other pictures of my old body... now remember I have to CUT that new one like that to make it fit.... I'm not worried about a scratch after cutting that much off :crzy: :lol:

Thanks




looking good buddy! jealous of all your run time!!

Thanks yo! Oh it's nice buddy! Not to mention the fun little invite only comps too...kind of fight club style but big buy ins and big payouts!!! Talk about pressure to win! When its $10-20 to buy in... t's game ON!!!!!


Thanks!!!




Just hope the weather cooperates... snowing right now and the southwest corner is getting it worse than we are. But Parker said rain/snow/sun its on!
