The problem that the FP motors faced was keeping the load up. We're using a 2.5" spool with the setup above. It takes about 40 pounds of force to lift our mechanism, but then when we get to the top, the FP motors don't hold the position.

So I was wondering what property of a motor helped to determine whether a motor will hold a load or not?

Also something else about our setup, we're running the motors with alligator clips from the battery, not through a motor controller. Is setting the motor to 0 on a motor controller different from simply removing power from the motor?

Thanks,

Sunny,
As a word of caution, the FP motors have a thermal cutout inside the motor. This might be the reason the FP's are not holding.
