What about the weight of the motors?

• ChuckMcM 13y ago
  The efficiency linking human motion to desired motion vs linking an electrical motor to the desired motion is pretty similar in my experience. Brushless motors are relatively light and pretty efficient (hence their use in models today). The human linkages (gears/chains/etc) are comparable in weight. Bottom line connecting the human energy to motion is different but from a weight/volume standpoint similar in both cases.

    Yeah, but you still have to account for the motor converting electrical to mechanical in the power output.
