My buddys NS is now totaled!! The plane decided to suddenly dive straight down from about 50 feet with out recovering. The battery still had almost a full charge on it and the winds were light. All 4 servos are stripped. The receiver doesn't even have a cracked case but its not putting out any signals to the servos. The plane acted the same before but recovered in the last 10 feet over the ground. I thought it might be the smallish battery pack and so we replaced it with a much larger capacity pack and it flew for several weekends until now. Now I suspect a crappy receiver. Any body else have this happen?!? [>:]
