So I did a little experiment last weekend... I took off tail low (basically only allowed the tail to rise a little once airspeed increased). The airplane was light on its feet early, but had to accelerate in ground effect for awhile before positive lift off (50 MPH or so, 60 is best rate). Controls were mushy and it felt like I was wallowing a bit before the climb. Then I tried a more usual technique (for me, at least). As soon as possible I lifted to tail by pushing foward on the yoke. The airplane was level and lifted itself off once airspeed increased (which provides the elevator sensation). The tail low technique should be the more effective takeoff since the weight is transferred to the wings sooner and the airplane is at a flying AoA tail low anyway. However, the high AoA produces lots of induced drag, which will delay acceleration... The tail up technique reduces the AoA and keeps the wheels in contact, increasing rolling resistance. However, the low AoA means less induced, allowing faster acceleration... I wish I had a micrometer with me to measure the difference in takeoff run but quite frankly it was a dead heat to my calibrated takeoff run distance eyeball meter. So, what say you?
