Yeah, I think that FDR is abit high too. Also, look at the total motor speed in MM's post; 28k rpm. You'd need to gear up pretty high to get the speed you want with that motor speed. I would suggest going with higher voltage or slightly higher kv motor to get rpms in the 35k range. Then you'll see you won't need such high gearing.
