AM/FM or 2.4ghz? so it just glitches for a split second then goes back to normal?

I'm using 2.4. It's definitely comes and goes, but is often enough that I can't really drive the vehicle consistently. I'm just wondering if anyone else has had a similar experience with a RX8? My first RX8 just stopped working, but it seems this one is going out slowly.

does it happen after jumps, or just driving around??
does the steering cut out also?
is it overheating?

check

wires for kinks/brakes
loose solder joints
bad solder jab on the posts/motor
loose plugs on the RX/motor/batt
make sure the switch is working properly and not flipping off when jarred
cut wires(especially the RX plug, and switch)
make sure the sensor plug is all the way in(if using a sensored motor)

It only happens at the track, which does have some big jumps. I did a bench test at home and then drove it around on the street for 15 min and it did not glitch, but hit a few jumps at the track and it's a problem.

I'll re-check all the wiring, but it looked good the other day. I think the PCB in the ESC is going bad and it's only a matter of time till it quits all together. Not a big deal. This one has not been in for warranty yet and it is a V1 of the RX8.

it might be the pot on the bottom of the lower board in the esc, there is a known problem with a solder joint coming loose.

5R6 chip on the bottom
