Red Butterfly, small field Flyer

The Red Butterfly can fly tightly.
Low wing loading allows model to fly slowly at minimum throttle and the large rudder has good yaw authority. Rudder coupled with ailerons resulted in small turn radius, and crossing controls will direct the model to do a flat turn.
What is necessary though is 3S to overcome all that drag from the wing. Flying on 2S will mean the model will lose the energy and lose height.
Maybe 2S will work on smaller wings.
