Has anyone came across these things going haywire on you? I had a few decent flights last night and decided to get some practice this morning. Had the heli up and hovering around trying to get my hover skills going and the thing took off to the left and I brought it down but it had a hard landing. The one blade was flipped upside down and when I picked the heli up to swap it around the main motor engaged at full throttle. I had to hold the blades with some help so that I could disconnect the battery. now everytime I plug in the battery the main motor is always engaged at full throttle regardless of the control position. Anyone ever experience anything like this?
