Any more nose-up than this tends to generate more drag than lift, with the consequent serious problems of a tip-stall. Several planes "fell" into this situation.
The nearly level fuselage on the McGill entry is perfect.. just a tad of up elevator was needed to rotate to liftoff.. right at the limit line!
...
The nose on this one should not have been this high at takeoff! In the 2nd image the tip-stall has started.. Recovery is only possible with -rudder- and elevator!
...
Over it goes.... the left wing hits the ground and breaks, in image 4... \interesting thing about tip stallls.... the "recovery aileron" keeps the down-going wing stalled!
