Opjose: Interesting so you had the model run down forever and then suddenly shoot straight up, stall and fall back down misserably? My plane should have unlimited vert so not sure how bad this will effect me. You could pull the nose back down before it stalled once it was airborne? Also how bad was your negative incidence, what was the difference between rear wheels and nose wheel?
I got the plane's nose down, but I was lucky because it was wallowing around.
Having "unlimited" vertical really has nothing to do with it.
With the .76 engine I have no problems what so ever with verticals.
The problem is that the wings suddenly go into a high alpha and the control surfaces become ineffective, causing the plane to wallow around, while you are very close to the ground. I almost lost the plane as a result.
After this I adjusted the incidence and take offs have been uneventful.
