I bought this ARF on Saturday morning. Spent the weekend putting it together and today I maidened it. The maiden flight went well. I'm a total newbie at 3-D flying. I play with it a lot on my G3 sim but never done it in real life. On the suggested low rates with about 25 - 30% expo it handled like a baby. I flipped the switches for high rates and played around a bit but got kind of nervous because I haven't got around to putting stripes on the bottom of the wing yet and orientation with this plane is very difficult when you are 2 or 3 mistakes high. Anyway, on about the 4th or 5th flight I had just tumbled the plane end over end and had pulled out of the dive when at least one of my elevators started fluttering VIOLENTLY. The plane didn't have excessive speed or anything. I chopped the throttle and the flutter stopped and I landed. Upon examination I discovered that the flutter had caused the fuselage to crack and split right in front of the horizontal stabilizer. All of my hinges are still attached properly and I'm sure that is not where the problem lies. What would cause this to happen? The plane was handling so well up until that point and don't know what happened. Any suggestions? I will try to get around to posting some pics of the damage tomorrow and maybe you guys can give me tips on repairing it. It sucks to have to repair a brand new airplane.

Thanks!
