Well when i thought this might be a case of over voltage the first thing i did was to look at the ar6000 stats. what i found is that spectrums run on a 3.5-9.6v range. the speed control i am using on the ne motor i got is a jeti eco 12. The details i found on this esc is that the bec supplies 5v to the reciever and servos. In light of these new details i am confused once more. if someone can help explain/diagnose my problem that would be great.
