I agree with alot of the responses that flaperons on a P-51 are bad. Did just that, set up a P-51 with flaperons, came in to land with them down and the plane did in fact slow. So slow that the wing stalled at 25 feet above the ground and tip to the left and nosed in. I had straight flaperons on the flap dial (no mixing), seen that it looked like the plane was going to stall (sight and very mushy controls), added power and then it just tipped wing and fell. Ihave the plane ready for new covering now and when i get it into the air again i think i will just land it hot and NOT touch that dial.
