I'll post in both places. We've had good luck with the FP DeWalts with one modification. A .1250-.1245 hole in the pinion makes for an incredibly hard press fit on the FP shaft. We bent several FP shafts trying to get the pinion on. We even had a spectacularly buckled shaft from the LSR machine shop trying to press one on. Our solution was to move up to a .1255 reamer, which makes for a much easier press fit that's still plenty tight, even running 2 FPs back to back.

Second, we dremel modified the front plate to make some slots for a little airflow since the FP sucks air from the front. The trick is getting the slots close enough to the outer edge that they clear the body of the motor.

Oh yeah. I'll post the details of running FPs back to back if the Killer Bees don't show up and take credit for their idea.
