Flaps on Great Planes Cessna 182
If you have a computer radio you could simply setup the stock Cessna with flaperons which allows your ailerons to drop down like flaps either with the flip of a switch or the knob. All the time keeping control because the ailerons will still function as normal just in a dropped down position. I have used it on a couple planes and it works fine. Flaps are fun to play with ill admit but this system requires no modifications to the plane itself.
