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.

While it'd be lighter weight I would be worried that the tape could fail. I know it worked in on-road for years but the only "hits" they take are crashes. An off road car is jolted several times per lap no matter what.

I kinda' miss the velcro in my old RM car. Light & reliable, seems like it's a better solution than tape.

What are the AE guys taping to? are they cutting loops into their side-guards?

Yeah, how are both taping to their cars. Please don't tell me they are going all the way around the chassis? Of course, fast isn't always pretty. On a side note, the strapping tape that it used in on-road it dang strong. I've seen some really nasty on-road crashes and amazingly, the batteries are still held in place. Of course, I've seen batteries come out and go sliding across the track from a simple turn.

The battery strap anchoring to the waterfall and mounting to the posts is an integral part of the chassis structure and flex. I do NOT recommend removing it.

I suspect that the imbalance is due to external transmission (spur, pinion, motor plate & cover) since it is the only non-symmetric component of the car.
Is this typical to have to add 60g just to balance the transmission?

Also, what is the suggested front to rear balance to start with?
Do a double check on your shock collars and make sure your shock preload is even. I would figure you would have that detail down if you are you going to this extreme but this is odd. What motor you running?

Are they yanking their packs every run or charging in the chassis?

This is my first attempt at "balancing" a car. I probably wouldn't have bothered, but my car is ~90g under weight and I just wanted to optimize the placement of that weight.

The attached images show how I have balanced the car. The scales show that the rear is ~10g unbalanced. To get it to balance out completely I had to add ~60g of weights next to the motor bell end. This also shows nicely perfect balance by suspending the car in air using two picks, one on the rear wing mount center screw (unique to the 3.0) and one on the center of the front bulk head, just above the bumper.

Not sure if anyone has been this particular about left to right balance, but I thought I would give it a try.

Bummer, I guess I went overboard on eliminating weight buy not installing the battery latch and using velcro to mount the battery.

I have run two races so far this way. Not sure how the extra flex is affecting performance yet. Eventually, I will have to try it with the battery latch installed.
