[QUOTE="rerfurt, post: 1223907, member: 62143"] Thanks steve.emma I disassembled the RC controller and found that it is a normal 12v DC motor, not a stepper motor. The position detection mechanism is a normal 5k Ohm potentiometer similar to the type found in older stereo's. Both items appear to be operating ok, when connected to 12 VDC - I find no error. I have tried jamming the arm, but only when the engine was cold (neighbours!!!), I will try it with a warm engine on tuesday, out on the track - The cold trial run did display lack of top end power similar to what I have experienced, but the engine started sputtering and I couldn't tell whether it was because it was cold or because the powervalve was jammed.
