Cessna and Piper singles are not exactly "heavy iron".
- although some instructors seem to think so, judging by the dissecting of the various configurations and flying techniques discussed here.
If there was something special about touch and go handling that was critical for the type, then presumably the manufacturer would publish it in the POH. The C150/172, and Piper/Beechcraft variants are designed with low hour student pilots in mind, and are viceless.
Therefore, make it simple. After touch-down, select flaps up and as soon as the flaps are up, apply full throttle and lift off at normal POH speed. There is no need to reset the elevator trim to the take-off position because the stick forces are easy to overcome.
On the other hand, to lift off with full flap down then stuff around milking the flaps up at some indeterminate height, is an uncomfortable maneouvre requiring a close eye on airspeed control and nose attitude. And so unnecessary.
