Big Al,

If the craft balloons on landing then the air speed is still to high at the point of rotation or round out.

I have often reduced the prop pitch to as low a pitch as possible in order that the idle engine RPM thrust will not still overcome the drag factor. The craft will then slow as the nose is slowly raised, which of course increases angle of attack and adds more and more drag thus increasing sink rate.

I practice attempting to hold the craft off the runway at 2-3 inches for as long as it will fly. The idea is for the craft to no longer be flying at the touch down point. Air speed too low and angle of attack to high equals a stalled condition at touchdown.

Another hint, is to trim the craft for landing just as you would when flying a full scale craft. On the down wind leg, power is pulled back and the elevator is reset for a descending glide. If this is done correctly, dropping power will steepen the descent and not gain speed as the elevator is controlling the angle of attack and air speed. If the craft needs to land further up the field, add one notch of power and the glide slope will be at a reduced angle and lengthen the touch down point. When you round out just off the run way, reduce the engine to the idle setting.

Best regards,
