We just got a Duo 3 brushless motor, and was wondering where the 0 degree mark is? No numbers on the marks. Which mark is the 0 mark?

Please don't answer unless you know (no guessing)

Thanks everybody for your feedback.

The mark that it's on now is 0 it's a little longer than the rest of the marks.

I wondered the same thing, why don't they put some numbers on there so we don't have to guess? So what is that mark all by itself to the left?

My Orion is like that, too. Just a long mark in the middle for Neutral timing. If it follows Novak (which are marked by number), each tick mark would be about 5*.

It's a negative sign. For retarded timing, instead of advanced timing on the positive side.

Not sure, but it's my understanding that at 0 it still has some mechanical timing built in, I don't think 0 is really an absolute 0.
