[:@] Well I'm pissed right now! Ok, so I got my parts from heliproz quickly and got what I ordered. After dinner I went to replacing the main shaft, blades and installing the new 9t motor. For my first test I left the 10t motor in and did a quick hover. The blade tracking was way off so I got that fixed. Installed the new motor and went out again for a test flight. I had it in a hover for about a minute when I lost tail control. I was close enough to the ground and got it back on the skids no problem. I looked at the LED and it was steady red and the tail motor would not work at all. I figured that it was dead but wanted to reset the 4 in 1. It reset fine and I got a steady green light. Go back into a hover and the same thing happened. I reset it again and hovered for about 1:30 and decided to get a bit higher and away from the wife and kid. Well.....about 15 ft up in a hover and I lost the tail completely. I gave negative to get it down and told the wife to watch it. It hit the ground and started to do the funky chicken even with the throttle all the way down. Looks like I only ruined a set of blades but it still pisses me off. I took it in the garage and tested it while holding it to the desk. I would have it at half stick and it would quit and the LED would flash green/red very fast. Is this the typical 4 in 1 problem? Should I send it back? I'm not new to helis and have successfully flown my blade for a few hours.
