Motor Question

[JTTG]

So...running 2 motors on an MOA.

Tell me if any of this is incorrect :-/

Front motor spins regular direction (clockwise), rear will spin opposite (counter clockwise). I heard motors come advanced a few degrees so wouldn't just wiring the + to - and - to + retard the rear while the front is still advanced? How do you keep the timing the same on both motors but make them both spin the proper direction? Would rotating the end bell 180* and wiring + to + and - to - be the best option?

What do I need to know about wiring two motors for an MOA. Thanks!

Generally yes, but they might not be advanced. Even at slow speeds motors like a little advance for max efficiency.

Adjust the timing. Look at one of the endbell screws, there will be a little timing mark or notch in both the endbell and the can. If it is advanced, there will be a small gap between the two marks. Turn the endbell so the screw is on the opposite side of the notch, and the same distance between the notches as it was before. If it was not advanced, turn the endbell the opposite direction the armature will spin. 1/8" between the marks is a decent amount of advance for a crawler.

Generally yes, but it won't affect performance if you don't.

Mark the motors so if you ever take them off at the same time you can put them back on where they came off......

I would also check out this thread. It has some great info about adjust the timing on your Brushed crawler motor.

A thing I thought of... Are the Bully MOA axles geared so that when both motors spin the same direction, the tires spin the same direction? Or does the rear need to spin the opposite?
