Ball screws are nice but expensive. We have more friction and reduction
so I hope this does not happen to us. I would hate to have to readjust
the prop if the RPM creeps up.

Is that Pittman motor a permanent magnet motor?  If so, design a provision in
the circuit to short the motor.  That will 'brake' the motor and prevent it
from rotating.

Thanks Marc. Good idea. I will bet that will works on yours too Jeff.
