***edit, just noticed first page has this info. thanks***

What FDR should I gear for? I didn't see any recommendations for 540 motors.

I have a Novak 6.5 Lite and installed a 15T pinion to start. Haven't tried it but wanted to go on the safe side. It has the stock 93T spur.

15T a good choice or should I be trying for a different FDR?

Thanks
