We have done it for two years now and even under a high load they always held up for arms, turrets, transmissions, etc. We cut the gears ourselves. However if you were designing a transmission that will go several billion revs and needed to be ultra-quiet you would obviously mate the pinion with a true Metric gear.

For reference; If you need a true 32DP gear for the FP motor,
the sun gear for the AM planetary is a nice fit. It is ready to press onto a FP shaft and is 15T 32DP.
