Let me answer for 威威, he has tried, 64 pitch spur gear from TOP, Xeron, Kawada.
It is a problem of gear box or some design.

I push a 4.0 motor on F103 with 64 pitch, still can last for very long time. And of course rocket speed at GP track.

Yours are not CRC!? The problem seems to appear on CRC Pro10

Thanks Ken, may be the bigger spur the better
