On my MT electric constant speed prop, loss of power leave the blades at the exact pitch setting just prior to power loss. No power to drive motor stops any prop pitch change movement. I have noticed on my backup battery duration tests, my MT prop controller is one of the first items to drop out as battery levels decrease.

Got it, than you. How do you like your my pro? I am in a partnership building an RV9a, will have a O-320 (160hp) and he already have the my electric CS to install when the time comes.
I have no experience with the electric CS,
