Thanx for the advice, after looking at my post, gearing seems....scewed,
will do this friday, much cooler temps though, think your info. is the ticket.

Gonna make you a trade, cogging? Well..... ONE more thing to check if your sensored, mech. timing, adjustable, motor is cogging, remove the rear cover, look close at the sensor plate/rear bear housing, look for "shiny' spots, where the p/c paths terminate, w/ solder. TOO much solder will/can/HAS caused the circuits to ground out on the rear cover itself when tightened down.
Will act like sensor harness is un-plugged, ie; un-plug sensor harness, cogging still remains, after all else has been elimated, BINGO!
Can/will inhibit ESC timing adjustment, lost a bunch O hairs over that one!

THANK YOU for your time, knowledge, and advice.
CHEERS!
