RC plane Cessna crashes while looping

Here you see my brother flying the RC Cessna powered with a strong brushless motor and 9x5,7 on 3s Lipo. It was a very windy day but we had successful flights before this accident :) as he tries to fly a looping the Cessna blows up and we see parts of the wing flying down to ground. The rest of the plane wasn't able to controlled of course and it crashed with high speed to the ground. As I was focused on my digicam while recording this I realized the crash and wanted to see it with my eyes. That's why unfortunately I stopped focus on the crashed plane cauz I looked at it and had to laugh :)

REST IN PEACE lovely Cessna, we had spent great times together and did a lot of tests with you...we always will remember you *LoL* :)

too windy for that electric model buy a real plane a nitro power can fly in wild windy days

No it's not.I flew on much more windy days, check my other video too. The Cessna crashed because of its high power and doing the looping at full speed (too much Gs on the wings). By the way: a nitro powered RC plane has nothing to do with windy days, it depends on the model and its weight.

WOW. loops are only 1.5-2 gforces. You got ripped apart right at the beginning it appears. Which means the wing struts were weak or non-existent. I don't seem to see any. If you want to put the same forces on the wing. You need to create some sort of strengthening. Wing struts or an alternative.

Yes, it seems that the wing was already overloaded one flight before. My brother told me that he saw that the wing bended during a looping he made. Me myself didn't recognize it because I looked at the cam sceen. Afterwards he asked me if I saw that, because the wing was really hard bended through the looping he flew. Maybe this resultet in a damage of the wing which optically was not recognizably after landing. Who knows ... :) Anyway,this cessna was designed for testing purposes, no matter ;)

If you have another of these. Just get some fishing wire or something. Tie it so there is a slight taughtness to it but isn't changing the shape of the wing. This way there is something which is pulling the wing down from bending up under the forces. The plane is pretty decent but it is a micro which is expected to be flying inside a gym or something. Soon as you add wind and gforce maneuvers; without wing struts. You are going to stress the wing and weaken it to breaking.

Thanks for your advice. I think the problem was not the wing itself, cauz we flew this cessna many many times before with various loopings and nothing happened. I'm sure this accident occured because we used a bigger propeller. Normally we flew with the 9x4,7 which already achieved much power. Then we tried 9x5,7 which was too high as we realized ;) the cessna got a lot of speed with this propeller and that's why it has broken I think.

Yes that would also do it. Still by creating some wing struts it would have kept that from dieing.
