And I still put some current limiting in the new motors. Both have plenty of power to be competitive on our track and they are both much, much easier for me to drive.
I've got that almost brand new 6.5 sitting in a drawer if I get to the point where I think the power will be useful for me. But I've got plenty of room to add timing and or current without the motors or speed controllers getting too hot.

Hmm, thanks for this. I've got a 7.5 in my xb4, I may swap my 10.5 in, and see if that's better. 100x40 astroturf track, so plenty of traction.
Just wish they had a 13.5 class for the 2wd buggy. Having way too much issue getting enough speed out of my 17.5 to make the jumps.
