The Chiaphua gear is NOT 32 DP. It is a 36 DP gear. It is also not standard in that it uses a 25 degree pressure angle AND it is enlarged -- the gear data is on the print that I posted on this site and (less legibly) in Update #1 from FIRST.

The Fisher Price IS a 32 DP gear. It is a more or less garden variety 20 degree pressure angle, full depth gear (the profile is not quite the standard used for steel, but it is close enough for anything we at FIRST will ever care about).

Before you ask, the drill motor is a standard, 0.7 module, 20 degree pressure angle, full depth gear.
