Well, here is my CRT.5e

[brainanator]

I've run some slash tires on it for the football field and for on-road. It really bumps up the height a lot, traction rolls a little more. Haven't tried any legit 2.2 wheels and tires though.

The spot is the old little track that was made by the local RC club. They/we had to move because someone developed the land next door with apartments, and the developer didn't like the nitro noise. So the RCs got kicked out. I still run electric there. It has since been taken over by the local bike kids, so most of the jumps are poorly maintained, and the biggest jump (the big double) isn't even able to be used by the little guy, Savage can still hit it though.
