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.

Like Kraig said it is all about what motor and how your track is. I run a Tekin gen 3 17.5 with can timing at 50 and 75/32 for gearing, and that is what I run on outside dirt track and indoor clay. Penn01 you asked about hubs, and I moved them forward to have 1mm in the front and 3mm in the rear and it did help rear bite and forward drive.

I have a Motiv motor, timing between 40-50 on the can, track is 100x48ish, grip is on the high side but not damp dirt/clay, and I would start at 70 spur 28 pinion based on that information.
100 x50 sounds about correct for my usual track. Pittstop hobbies, surface is mainly clay. Smooth and medium bite. Grooves but doesn't hold rubber.
I'm running a hw 3.1 stock. And a amain eco 17.5 motor at 35-45 timing dependant on straight, and needed torque for track conditions. Ie jumps our of corners. I don't fall into the weight weenie category. Still run a slipper, but do degrease my bearings.
And thank you, settings seem close so I'll give that a try to start with

Not everyone has the same page setups. Just link to the post through the number in the upper right corner.

I am running the Exotek but with a ball diff. I have to say it is awesome. I went from the B Main to TQ in my quals. The buggy just hooked up for me. I have a gear diff but haven't tried it yet. All the Losi guys at our track are running ball diffs.

I don't have experience on the exotek since I use the Losi conversion but I would assume the gear diff should fit the exotek no problem though. I've been using a gear diff almost since I got the car only because its easier for me since I came from 8th scale. I started with the Losi gear diff but did not like the quality of it so I switched to the Serpent diff. Its a huge improvement over the Losi rtr diff. Been running 2k in it at Thornhill. I had to remove the thin shims in the Losi gear diff to get it smooth. The pins that hold the outdrives in were biting into the shims and creating binding issues. Unfortunately the pin length is the same as the diameter of the o-ring and the outdrive/pin can be pulled out of its slot in the drive gear. I tried a longer pin but the slot in the drive gear would have taken more tooling than I was willing to do. At that point the outdrives were already getting sloppy in the diff. Easier to order the serpent diff.

With the TLR lay down conversion kit, what rear hub ball stud hole are most using with the +3 alum hubs? Are they the same as the reg 22 alum hubs with the 2 inner most holes on each row being extra ones compared to the standard hubs? Set ups call for "A " ball stud hole. Is that middle hole front row of the hub, if your comparing it to the standard hub?

Any help would be greatly appreciated. Call me VERY confused.

I believe somewhere I remember reading Frank stating he would start with the middle hole in the back row.

Middle hole back row seems to be what most people are running with he laydown. This would be the equivalent to the "A" ballstud hole.

Could you tell me what part number it has?
I'm searching for just the diff 'body' for a friend's 22 1.0 but I can't find it anywhere on the tlracing website. Seems like it won't be sold anymore?
Need a spare after some years.
