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.

This post I made a few weeks ago should answer your first two questions.

Yes I have run it and I thought the car was great as well as durable. The first time I ran it in stock buggy at my track I TQ'd and won.

Worlds car adaptation, i club race with Dustin and TLR is putting some work in on a lowcg/carpet turf hybrid for the future. From the engineeering side of it the laydown tranny(transmission raised off chassis) isnt enough, roll center geometry needs to change at ride height since its in some cases 6 to 7 mm lower than before hence new hubs

Once I had built some confidence with the car and my driving, I decided to add the front wing and see what happened. After a couple laps, I was convinced that it was a benefit to my car and current setup. However, there are only 2-3 of us at our local track running them. Almost all the drivers have more experience than myself and consistently kick my butt without them. But, it seems to work for me and make my car a little better than without it.

Those are pure prototype and we will not be releasing them.

I have no skin in the game, so I'll give a 3rd party assessment:

I stopped by Nick's pit at a race we both attended and looked at the car for a few seconds. It looks very professionally done. All the cuts are smooth and consistent, no jagged edges, great finish. It looked very structurally sound, and looked good on the track too. .

I'm pretty picky, so I was impressed that I was impressed!

We were both in the 17.5 A main, though I think we each had a race we'd like to do over. But I'll put that on the drivers. LOL

From what I understand this one fits perfect. Everybody just recommends upgrading the orings rings to Kyosho ones.

I'll probably take some flack for this, but I don't think a gear diff is a must for carpet. I run on a tight (10-12 sec laps depending on layout),high bite ozite track every week from Sept. to March and my diffs hold up just fine. I've been running a 22T 2.0 all season and it's just now starting to feel a touch gritty. Only 3 races left so I'll just wait and rebuild it for next season. I make sure my slipper is actually slipping just a little bit. Just my .02, if it's even worth that lol.

I recommend the serpent srx2 diff. its amazing and it fits no problem with i think 3x .2mm kyosho shims on each side. its way better quality than the RTR 22 gear diff.

I was told to try 2 gear with 15k oil to have the gear diff feel similar to a ball diff on clay and still be good on carpet.

I actually blew out my first diff when I got my 3.0 but after I rebuilt it and properly broke it in, Butter... This video helped too

Hey, are you Bo or Rob? I run gear diffs at MBR Speed Shop. I think you could do ball diff if you either loosen your slipper pretty good, or you're running on dirt webs or something. But the pin tires are just way too much bite.

I use the Losi 22rtr diffs, but I've been thinking about trying the Serpent ones. The Losi are okay with different o-rings to stop the leaking, but the Serpent ones look much more durable. I also like that the gear is replaceable on the Serpent, whereas you'd have to replace the housing on the Losi if you chip a tooth on the gear.
