I have hacked up a couple of RC Servos via removing all the electronics and using them as inexpensive gearmotors. I now find that one is more efficient than the other. I am planning to use a Hall effect / PWM closed loop control structure to avoid this problem in the future, however I want to give a demonstration of what I have so far and I need the damn thing to go straight : ) . I was thinking about throwing a trimmer into the cicuit for the short term to balance out the problem. Any ideas on what range the pot should have...ie
100k? Whats the best method to figuriung this out? They motors prob recieve about 6 volts.Thanks,
Rick-
