Make sure that you can adjust the motor you are using at least to zero advance, if not with some advance in the reverse direction (which would be
retarded timing in the
normal direction of rotation). You can do this on Novak motors, but I've seen other brands where the timing is only suitable for normal rotation.
Novak marks their zero advance point as "N" for neutral on some motors, and 30 degrees on others. Novak's 30 degrees is the same as other manufacturer's 0 degrees. (This has to do with the electrical characteristics of brushless motors.)
By the way, you can use the reverse rotation feature (or simply full reverse, for that matter) on Novak ESCs to find the zero advance point on motors like the SS that don't have any markings for it. Rotate the end bell until the RPM is equal at full forward and full reverse. A tachometer is handy for this, but most people (especially those with some musical talent!) can get close enough by just listening to the pitch of the motor.
EDIT: SEE POST #11 FOR CORRECTION TO THE ABOVE ITEMS!
With the motor timing set correctly, the performance will be identical in either direction.
