I have been having the strangest problem with my speedo when I put it in my B44 and started to try mod motors. It ran perfectly with my stock motors and Checkpoint 19t money motor, not a single problem.

Here is the problem, when I put my 10x2 checkpoint, or 8x1 P-94 and I get to 3/4 throttle, the servo glitches and speedo go from full throttle to full brake repeatedly until I let off the throttle. It does this on new brushes, clean cut comms, and new caps on the motors. When I use my NiMh sattle packs, I can get a slightly more throttle before it starts to glitch then my Lipos(smc 4900mAh). Motor timing is set at 0 degrees. I am using an Airtronics M8 with 75mhz synthisizer set up.

I am at a loss with this one. If I pull the motor off and run it it works just fine, but when I put even the slightest load on the motor it starts to glitch.

Any Ideas?
