This item is very useful, not just as a replacement if you break your F929/939 gearbox, but also for other scratcbuild projects. I have used them in several projects, including a Flitetest Mini Scout built from 3mm depron to 75% scale. The good thing is that any 8mm coreless motor will fit in it, and the pinion size is the same as the Parkzone micros such as the P-51. So you could use it as a replacement for the Parkzone gearbox on any Parkzone micro that uses the 8mm sized motor. MUCH cheaper than the Parkzond parts.
