|Power Functions S-Motor|
I've seen some of these floating around, but most of 'em are just edited photos of the current motors.
So, I think I'll take a crack at it too!
S stands for 'Small', in this case. It might get mixed up with the Servo Motor...
The entire motor would be on a 2 x 4 base, and be about 5 plates high.
(Pictures coming soon, need to draw them out first!)
