What did I do wrong
I had a peculiar problem today that scared the hell out of me. I put a partially depleted battery pack (2600 NIMH) in my Corona to run the battery down. The heli fired up and began to skirt around the ground and I had no control over the throttle. My throttle lever was down, and I still had power to the controls because I could still change the direction it was skirting. (Not having enough energy to lift, but enough to slide around)
I've never experienced this before, and when I put a fresh battery in, all was ok again........any hints? corrections? go to stupid school?......what...
