Why do you need that stepped down 1:40? Seems like a LOT of torque.
I used the great gear to attach a lever that would convert the rotation into a left-right movement of the "tentacles" of my slug robot.
As this movement should be very slow, the stepping down was on purpose then.
Yet, I agree that for other applications you would want to use a smaller gear (the design shouldn't be too difficult to change in this case).
BTW, my numbers were wrong -- here is a good comparison of all LEGO motors.
The NXT has an RPM of about 170 and when loaded generates a torque of about 17 N.cm. If you were using that power, you'd be generating 680 N.cm. of torque. E-gads!
Good thing all you're doing is swaying tentacles!
