Re Approach and landing technique in C152 et al. Keep the exercise simple. Turn base, and when you can comfortably glide in, close the throttle fully. Use flap as needed (not merely by rote)and aim to cross the fence at 54 knots with full flap. Immediately after touch down, raise the flaps fully and apply full throttle. Rotate at 54 knots. The trim forces in the 152 are dead easy to hold at any stage of flight. It is designed that way. Repeat exercise ad nauseum (or money runs out for the day) until solo.
The C152 was designed to be safe and simple to fly. Warriors too. The trim forces are minimal and the POH states that normal landing approaches can be made with power-on or power-off. Same as a Tiger Moth!!
You do not need flaps for take off or touch and go. Glide approaches taught from the first circuits teach early judgement skills which will prove useful in case of forced landing.
From a student's point of view, the myriad of combinations of throttle settings, versus incremental flap positions plus differing target speeds for each flap setting
that some schools teach, is bewildering and quite unnecessary. Avoid gimmicky techniques which abound at flying schools. Read the manufacturer's POH and be guided by the advice therein.
