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.

Yeah its the newer RSX, more power and more suited toward mod class or 4wd buggy, than the RS Gen 2. I'm running it without the fan because its only 2wd 7.5t so not stressing the unit much.

Have you ever run a mod buggy? Things happen so much more quickly with a buggy with a 7.5 than a SCT with a 17.5. Small mistakes translate into big crashes. That super pretty buggy is going to take a lot of abuse if you've only been racing r/c cars for a little bit.

been into RC on and off for years. but relatively new to the class. i usually just dial the epas back on my radio for indoor tracks.

Lowering the EPA is the worst way to change the feel and hit of a low turn mod motor, in a light car, on high traction surfaces. Ultimately the best way to make the car more controlable is to go with something like a 13.5 of 10.5. A little more than a 17.5, that way you won't have to drive perfect line to get over some of the harder jumps (if your tracks have jumps that are hard for 17.5's), but not so much that it makes the car hard to drive for someone that is just trying to get into buggies.

Your car looks nice for sure. Just a word of caution,carbon towers don't like to spend time on the ground. 2wd Mod Buggies are a blast to drive.

Picked up the losi gear diff yesterday, had to rebuild it due to all the fluid had leaked out in the bag.....as I rebuilt it I noticed that there was 2 shims under the drive pin on the cap side of the diff and only 1 on the cup side......is this normal? Are 2 needed or could it just be that when it was assembled at the factory 2 stuck together? Thanks for any help....FYI the local guys are running it 4 gear with Hudy 2000 on carpet......again thanks for any help

Mine was the same way. Put it back together the same way. No issues. You'll have to be the judge though.

I'm just rebuilding my gear diff ( 22 2.0 ) I had all 4 gears in it and 3k fluid. A few guys around here have only been running 2 of the inner gears and 7k - 10k fluid. Seems to work well. I'm going to give it a shot.

I also run on carpet.

I also used the red Kyosho orings this time.

i appreciate that. i did sand down and tire glue the edges of the cf tower to help. but theres a huge outdoor astro track near my house, which is why i went with 7.5t for the summer. i just dial it back when in door, nothing crazy but just so its not a rocket ship and uncontrollable.

i will be sure to air on the cautious side as i get used to the class more and more

Can someone tell me if the kit comes with both a 78t and a 70t spur gear? Also, does it come with all of the popular servo horn adapters(23t, 24t and 25t)? Thanks

It does not come with the 70t spur. Does include all the servo horns in plastic.

im finally getting places on my carpet/turf conversion for the 3.0. i am building two versions of my transmission. one will drop right in to the stock chassis and the other mounts a carbon fiber shock tower right to the transmission case much like the yz2 and xb2. the full conversion uses a custom carbon fiber chassis in order to allow you to still use saddle/square and shorty packs in the car, the only body that will fit is a yz2 body.

i expect to have a prototype of both sometime during march.

It does come with 23, 24, 25T servo horns. It does not include the 70T spur gear this time.

Nothing wrong at all with dialing the EPA's in, that's what it is there for.

I don't necessarily agree with this.

If one has no throttle control, changing EPA will help. Just like if one has no throttle control, higher T motor will help.

On the other hand, with throttle control, I can drive my 7.5T and make it look like I am driving a 17.5T

It's all in the finger - practive, skills...
