Cain,
I don't figure out FDR. In my opinion FDR will get you in the ball park, but it doesn't give you the answer, so it can be a good tool, but there are too many variables to go just off FDR. Tires, tire wear, traction, surface, weight, brand motor (heck even motors from the same brand are slightly different from one another as far as torque and rpm go) and driving style all play a role in deciding what gearing you should run.

Gearing for me is more based off of what motor I am using, feel of the car, track layout and temperature. 160 degrees is the number you need to stay away from. Around 140-145 is probably optimal performance and keeping the motor durable/reliable long term. For me right now I am running a tekin gen 3 10.5t motor and running 80t spur and 20t pinion. I do not run a fan, do not run any timing and I come off the track after a 5 minute heat at 125. After the 8 minute main last time out I was still at that 125 temp. I can tell you it is not fast on the straights in comparison to the other guys at the track and its not near that 140 temp. I could probably go up 2 teeth on the pinion for our current layout to get the most out of the motor, but for me it is not needed right now.

the ball park is basically what we are looking for.

Helped a buddy with the bones issue. He is very faster driver but was having all sorts of fits over a jump. As soon as I showed him the issue he changed his diff height so it wouldn't bind, then went out and lit it up for the mains. He has bones now on the way lol.

We have been running the stock foam inserts in the swaggers here in Germany, the dirt tech closed cell insert is good for Schumacher staggers on EOS carpet.

Depending on the grip level it's either Schumacher Minipin yellow (silver in the wet) or JConcepts Pindowns with foam inserts. You can use either JConcepts or Schumacher foams, there is not much difference. I tried the Proline Pyramids on Saturday and they seem to be a decent alternative with a good wear rate. The Wedge front tyres are not as easy to drive as the Swaggers, but still way better than the Staggers.

Anyone else have play in the front axles?

mes

Yes, that is normal. I shimmed the front axles on both my son's truck and mine. Our club president didn't, and he is faster than both of us, so it seems it is not much of an issue.

What would be some good parts to have extra for this kit running on clay?

I would say arms, hinge pins, front pivot, front camber block, and maybe a set of shock caps. The steering rack seems pretty durable.

Then some ball cups for maintenance. They're fantastic but a smidge soft. Depending on how clean you drive you may wear them quickly.

thanks, much appreciated

Hi guys, I have a YZ2T on the way, two questions; What gearing for 13.5 blinky on carpet medium track, and Does the Jconcepts T6.1 Fin turnbuckles fit the truck (don't see a YZ2T specific one on the Jconcepts page). Thanks.

I wanted know are there any other places to find parts other than AMain? Can't seem to find parts
