Pace, with due respect, talk about handling twins on take-off, and considerations of engine failure, VMCA etc etc, contribute little to a discussion of techniques for handling small single-engine propeller aircraft with a tricycle undercarriage.

Such aircraft don't "Rotate", except in the mind of a pilot imagining he's in a B747; they fly off the ground when they are ready, and the pilot's job is to enable that to happen at the right airspeed by controlling attitude. You might argue that this is another way of saying "rotate at V1" but it isn't; the difference is that in a multi-you do not raise the nose during the take-off run, which would slow the aircraft, the rotation bit is raising the nose and stating the climb in the same movement. The SEP should lift off gently in the attitude it has been in all along the run, then raise the nose smoothly into a climb when the danger of sinking back has passed. That applies to tail-wheel and tricycle aircraft.

That said, there are emergency short field take-off techniques that work with certain aircraft and not others, which include heaving it off the ground quite violently, but that's for the experienced after they have learned to fly normally. I was taught to do it (as part of our normal Club post-PPL training, unlikely these days) in aircraft that had a manual flap lever (Auster, Tripacer) because the method was to set full power, no flap set, tighten the friction hard, check Ps and Ts, let the brakes go, and at full flap stall speed +5 KT heave the nose up sharply, while setting full flap simultaneously, whereupon the aircraft leaps off the ground like a startled rabbit. In a tail-dragger the tail is up by the time you do this (in the Auster you could get the tail up, carefully, before releasing the brakes, especially if there was a bit of headwind.). At 30 - 60ft you get the nose down smartly before the stall gets you, gain climb speed in level flight then climb away, then start milking in the flap. I forget the take off runs we achieved practising this, but they were very short. Electric flaps might be too slow, and if so you would have to set full flap before starting which I imagine would lengthen the run a bit.
