Default Does reversing motor effect mechanical timing?

Silly question. Running an 8.2E with Tekno. The configuration needs the motor to be reversed. Had to replace the bearings in my Reedy 1512 1800KV the other day. When putting it back together, I realized I forgot to mark and notice where the timing cap was adjusted. Then I started wondering where I should set it...not that I could find a mark or anything. Not sure if it matters on this motor anways...but the question remains, if the motor runs in the reverse rotation, is the mechanical timing effected? I know electronic, though my hot wire should compensate for the electrical timing since that is where I am telling it to reverse..but mechanically? Sorry if it seems silly, but I dont have an electrical kinda brain..or am I over thinking it? Just trying to not overheat the motor.

Yes the rotation will effect the mechanical timing of the motor.

Thank you, that's what I thought. I wasnt sure if the ESC electronically corrected it. Good info to know So with that said, I know most motors are timed up, even at the zero mark. So if I am running reverse, then it is actually retarded...so to make the mechanical timing effect on the motor as little as possible, I should set the endbell timing to the Retarded side...(CW) which would now be advancing it since it is counter-rotating.

Novak speed controls with software-selectable reverse rotation automatically advance the commutation pattern one state in reverse compared to forward. Since there are six commutation states and 360 degrees per rotation, that means that the timing is automatically advanced by 60 degrees for reverse rotation.

So, if you set the motor with 30 degrees of advance in the normal rotation, this same position will also give 30 degrees of advance for reverse rotation.

It's a convenient feature, especially for motors with limited timing adjustment (like the Novak SS).
