Cub86 posted the question: Hi. I'm struggling to understand the lay down situation. I run on high bite damp smooth clay and think the conversation would help on my surface but from what I'm reading I need to buy the lay down kit tlr338004. And the dirt gear case tlr332063. But do I really need both from what I've read the dirt case is 1-2mm higher anyway and u don't use the +3mm hubs or the front pivot hrc or Hrc mod. So is the dirt lay down kit tlr332063 is all that's needed to get me a lay down set up that's suited for clay With the components and car I already have. And if I only get the dirt case is there any problems that will need to be addressed IE.. bone plunge . I do know I'll need 1mm spacers on the waterfall to clear the battery. Thanks guys really trying to get my head around this.

Franks response:
Laydown Conversion will work great by itself. You run the aluminum +3mm hubs, the diff is +3.5mm, and you run the HRC front setup. Just follow a setup sheet from tlracing.com (Frank Root).

Dirt Tranny has the diff at the same height as the standard tranny case, and works with the standard plastic hubs. Both are +/- 0mm from stock. When you run this, no need to run the HRC front mod either.

I've found the stock laydown conversion parts to work great for most tracks. The dirt tranny is a great tuning option, but definitely not 'required'.

Something I made, pretty basic. Just to give people an idea.

I have a BIG problem with my dogbones however, my shocks are as short as I can get them, but they are in danger of falling out at max suspension travel. What's everyone doing here? I assume I'll have to put a 1-2mm shim under the piston to limit travel?

There are 1mm axle spacers that are included in the tuning bag. It's supposedly an option, but imo, it's mandatory. It's using the same dog bone as the 2.0 but that car never had this problem iirc.

I had to use the axle spacers though, I was hearing random gnarly sounds and saw that the bones were almost coming out at 29mm stroke shock setting.

It sounds like you figured out the source of your noise, but if not, maybe it is the diff gear interfering with the inside of the tranny case.

Can anyone else here confirm that they have successfully run the Losi gear diff in the 3-gear tranny case on the 3.0?
The noise I heard was the outdrives and bones so the shim on the axles did get the bones deeper into the outdrives.
I was kinda assuming that the gear diff may have a little difference in the overall width of the outdrives end to end so the shim was a solid remedy to take the guess work out of it.
I had no problem inside the case when the gear diff was installed and the cases closed.
Car is running fine with the 20k diff fluid inside.
Anything lighter seemed to be diffing out, inside rear tire spinning around corners.

It's been discussed several hundred times already and the bone doesn't pop out. We've had our car a month before it came out with several hard wrecks and it's never popped out. Put spacer in of you are worried. This car is way better right out of box than the completion and doesn't require tons of $$ to make it last.

Running 72/32 8 degrees timing on motor ( gen3 tekin ) that's at 15-20 minutes coming off at 167 feels spot on mix of tourq and top end just can't find the spec operating tempature range for tekin gen 3 , I'm running 17.5 tourq not rpm version , tekin web site states rpm version is more suited for carpet track

Yes, I should of read back thru previous post as this has been discussed in depth. I'll put it on the track as is, without the optional spacer.

Could someone answer me this--I built this with a short stack Mach3 17.5, are the short stack motors (1s) down on torque substantially from their standard counterparts? It seems like it when I was setting the slipper, that's for sure. I race indoor off-road and am a middle of the pack racer, thinking I should of opted for the standard version.

Believe it^^ Randy's son Tyler is always in contention for the TQ or win in mod classes. That kid could wheel and the couple times I seen this buggy it was dialed and without any issues. So much so that I got one.

Yes Randy I will be coming to you guys for setup tips.

I always gear for the best lap times and not temperature.

People have been losing their minds over this spacer. At this point it would have been less work for Losi to have you install it by default.

That being said, it shows that many consumers are more worried about how it looks than how it performs...

Especially when we are talking about stock motor times on 15 min. gear the shi% out of it for about the 8 min mark. there aren't very many stock mains over that time lot. if you aren't racing that's a different story.

Had a car once with dog bones that looked like the one above, and cost me a race when it popped out after a crash. Replaced it with a longer one, never had issues since. Guess I just have bad luck.
But I have no doubt that this car performs great out of the box.

I don't think you can fault someone from questioning the dog bones as NO other car has them that close to hanging out of the outdrives. Yes the car performs well but many of us all questioned the length of the bones Let's cut the guy a little slack
