Default what is purpose of advanced motor timing?

bought a used ax10, novak rooster crawler, 55t motor...

the motor definately runs faster in fwd than it does in rev. so it sounds like the timing is advanced.

so, is this bad? what is the advantage/disadvantage of advancing the timing on the motor? (other than much additional heat)

I wouldn't mess with timing for crawler motors. You typically would "time" a higher speed vehicle to gain RPM's. But in advancing the timing you gain speed in one direction (fwd or rev) but loose it in the opposite direction. In crawling this is not nessesary to increase fwd speed (by timing) because you loose rev power which is not a consern for a faster basher truck (loosing rev power)...

Your stock motor is at 0 deg timed. the reason your faster in fwd than in reverse is because of your stock speedo, it's a saftey thing. Most every RTR speedo has 100% fwd and 50% rev power. Hope this helps.

Not positive about that 50% reverse power thing...

I would guess about half the time I get a motor, any of them, it's a little faster in one direction. I always adjust the timing to make them a little faster going forward at the very least.

x2^ Some of the machine wound motors are not as equal. Also the break-in of the motor could effect the speed. Your brushes could be worn.
