We received our first two samples of this motor last night and they looked very promising for light loads. I had a whole bunch of questions for you but then I realized most are answered here:

One question remaining after reading the specs: Is it possible the output power curve is on an incorrectly labelled axis?
Example:
If you look at the peak power point at 11 N.m, the Input power should be 13V x 6A = 78 Watts.
The output power curve shows ~14W, and doublechecking torque & RPM confirms it at 13.8Watts
I don't expect high mechanical efficiency from a worm drive, but ~18% seems way off. Can you check and/or clarify? (Or correct me if I missed a unit conversion or decimal place.)
Regardless, it looks like a nice, light gearmotor option and the hall effect sensor makes it extra useful over a window motor. The challenge as you point out-- will be the relatively fragile output drive material, so that's a problem for us to solve. Square drive looks like an obvious solution, but more contact area would be better. Can you point us to a specific vehicle usage? We might be able to scrounge junkyard parts for the proper mating 8-point shaft. If the junction has survived automotive durability testing, it has a good shot at surviving FRC duty (if properly applied).
