Ihave found that to be the case with any model that has a flat-bottom wing/airfoil. Flaps give a scale appearance, but are misused often as a landing crutch when engine tune (low idle with prop braking) or proper approach would better accomplish soft landings.

Compared to full scale aircraftmodels get away with murder. The air is four to eight times as dense as the full-scale aircraft are working with (and relative winds similarly are that much faster for the model).

But flaps are cool. Ilike playing with them Nothing more graceful than a model crabbing in slow against a crosswind that rolls outjust a few feet upon wheel contact.
