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.

Frank, please correct me if I'm wrong.

This video is good for the rear motor cars, which IIRC are backwards to the mid motor cars because of where the weight is based on it's relationship to the rear axle.

Again, correct me if I'm wrong.

When you take out camber gain sure, but camber gain is > than roll center IMO, and the results are opposite

The physics/geometry for roll centers are not affected by the location of the motor.

Finally got my 3.0 built, hoping to get down to the local track this Friday for some practice laps and Saturday for its first race. Thanks to all for the setup tips! Will be the first buggy I've ran in years.

Any issue with polishing the Losi coated shock shafts? Any reason too? They seem pretty smooth and clean on their own. I was wondering if they will get better with polishing.

Not likely. It'd be difficult to find something hard enough to polish the surface to any finer a smoothness without removing the coating. They're really smooth, best to leave them and get a nice long life out of them.

Frank,

Any plan to offer the laydown hubs separately for those of us that want to give them the a go? Specifically for those that want to go the Exotek route?

They are already available separately. TLR334037.

I am not sure if the geometry will work at all with the Exotek, since their tranny geometry is different (although I don't know how). If might really mess up your bone plunge and cause the car to handle poorly.

I emailed exotek this question.

The response I received said their drivers have only tested with standard hubs (+3 hubs were not available during testing.) He said they found the standard hubs are/were perfectly fine and fast, but didn't see any issues with the +3 hubs. He said they might be a good option to try if you are trying to get higher roll center to free up the buggy mid corner.
I asked about the bone plunge, but no specific answers were given.


The feedback from both seems overwhelmingly positive, so I don't think there's a wrong choice.

FWIW,
I have the exotek & +3mm hubs coming in the mail, so we'll see what happens.

Frank, will TLR eventually release a lay down version 22 kit? Or will it remain a conversion?

No immediate plans.

As usually, even if there was, I definitely couldn't discuss them...

Prices of the laydown went up, and it's out of stock everywhere. Wonder if theres a molded version or other way to get this for cheaper.

I am pretty sure Pacific Coast Hobbies still have some on hand...

Oh man, I should have ordered one of those last week when it was cheaper and I was thinking about it.

I guess for now I'll stick with the stock kit plus the HRC pivots for carpet. It's not like it's the car holding me back at this point.

I have read in here people are using a Serpent SRX2 gear diff. Is this better than the MIP Super Ball Diff Upgrade? I will be on high traction indoor carpet with jumps if it matters. Also is it a direct fit swap other than shimming?

Thanks!
