too hot only affecting mid range?

Sounds like a problem with the speedo to me.

Which is weird, because it gets small pulses from the receiver, the length/speed of the pulses only change from half WOT to full WOT..

Did you checked your capacitors on the speedo? check them to see if they are not popped.

You could test another battery set if you have it. Sounds odd though, i can't imagine it are the batteries, but you'got to aim before you shoot, right?

I give up. I hooked up the brake servo so I can watch it and ran figure 8"S in the street for 4 minutes and I couldn't get it to screw up only happens at the track maybe? getting jarred from the jumps? bad solder joint????
anyway I put a heat sink from a computer on the motor and it is running MUCH cooler.

I noticed the caps on the controlleer are different temps. ONE is 130degrees and the others are 90 to 100.
