Are students really being taught to 'rotate' at a certain speed in a SEP? As has been said, that's entirely innappropriate in such an aeroplane - very poor technique.
I'm just learning the delights of the L4 Cub
Lovely fun aeroplane! I have fond memories of one of those I flew for a few years.
The stall warner in the Chippy is pre-stall buffet. For a soft field take off you can drag a Chippy into the air way on the back of the drag curve and accelerate in ground effect while 'feeling' the wing coming alive as the AoA is gradually reduced until the wing is in the positive side of the drag curve and a normal climb-away can be made. The ASI plays no part whatever in this.
