I see, missed that line of Chuck's. Well, whatever the theory, it doesn't seem to be born out in practice.
What I was pointing out is if you are trying to full stall that airplane and touch down on all three wheels at once and the touch down occurs before the wing stalls there is still lift being produced because the angle of attack with all three wheels on the ground is not sufficient to stall the wing....
..but I could be wrong and won't lose any sleep over it..by the way..no I have not flown the C150 with the early conversion using the main gear that came with the airplane.
