I may not have been clear about what's going on. The gear are coming up, going down, cycling uncommanded, I'm not moving the gear switch at all. Gear switch is in the down position. They only start to malfunction once the engine is running and just above idle. I have stirred the sticks on the transmitter and operated the gear to maximize the batt load and they work, go up and down responding to the gear switch normally ( without the engine running ) . With the engine running, they go up and down, independently, and I am not moving the gear switch.
