The numbers for the am-2161 appear to be self-contradictory. The 174 max watts number is inconsistent with 5700 free rpm and 35 oz-in stall torque numbers.

Assuming a linear speed vs torque curve, the max power would be (5700/2)*(35/2)/12/16*0.14198 ≈ 37 watts. So something's not right.

And that 37 watts number can't be right either, because if you run that thru a 71:1 gearbox you're not going to get 44 watts output (as spec'd for the am-0914).
