The discoveries keep coming.

and btw my sincere apologies to the good people at Nitroplanes for jumping to the conclusion of a bad ESC. :-) I installed a spare 100amp ESC that I had and the problem (twitching servos) was still there. So then i disconnected the red (middle) power wire coming from the ESC and plugged the rx batt pack back in and the problem goes away.

Now it seems to me that these servos (spectrum A6060) are incompatible with the power from a BEC, or at least a 'built in' BEC. I still have not tried an external BEC ???

Has anyone else run into this problem?<br type="_moz" />
