I have a friend who has a theory on pretty much everything. He normally flies a C182 and hits the flaps down two detents at about 25kts. That's fine in the C182, but put him now in a C150. Same trick hits the flaps without looking at 25kts, not realising they will cycle all the way down to 40 deg droop...... Seen him do it and he had no idea that he would be stuck in a bush if I hadn't copped his mistake.
Manual flaps are an excellent tool for STOL ops. Foostering with electric ones is not worth the hassle, just set them and go. Nice vid's of the Maule btw. They are a cool as airplane in my books.
