Well, today my dad told me had been going full throttle (I did'nt even notice) and I thought he had control of the plane and did not take it away from him. AS a forethought the engine was giving 8500 ground rpm on that 15x10 and that is at least 80 mph but in a dive that is probably close to 100mph on the ultra stick that is really not made for speed, well maybe if I had reinforced the wing dowels with something it would have withstood a little longer but....hope I can find the wings since I have a new fuse at home.

It looked great the wing just rolled off of the plane and didnt stop rolling till it was somewhere near the ground when we lost sight of it. at least there wasn't too much damage to the engine just the valve covers and the valve guides.

Thanx for everyones interest.
