I've been having an issue with my IVO Medium lately and not being very familiar with the design, I thought I'd ask the members for some help.

When toggling the pitch control on the ground, I can hear the prop trying to change pitch but then the circuit breaker pops. This happens in either direction. When I switch it over to auto, I can hear the prop clicking every few seconds as it is trying to change pitch but it is definitely not moving. The CB does not pop when I have it in auto. This same scenario occurs in flight.

My call to the IVO company last week was unproductive. They just said that it sounds like an electrical problem (duh!!!) and for me to remove the prop and send in the hub for repairs.

Thanks for any replies.
