This vid shows a 3ch single prop plane maneuvering. It does not have aileron. It uses rudder and elevator for control.
A 3-channel single-propeller plane without ailerons relies on the rudder and elevator for primary control, along with throttle for speed. The absence of ailerons simplifies the control system but also imposes limitations on the aircraft’s maneuverability and performance. To be precise, the absence of ailerons reduces the complexity of the aircraft’s structure and control system. This simplicity is particularly beneficial for beginner pilots, as it makes the plane easier to build, maintain, and operate. HOWEVER, this is not ideal for pilots seeking to perform advanced or aerobatic maneuvers, as the control system cannot provide the responsiveness required for precise roll control. Without ailerons, the plane may struggle to counteract crosswinds effectively, as rudder inputs alone may not provide enough control to maintain a stable and coordinated flight path.
