In order to understand or use an Airplane RPAS, users must have an idea of how each part of the plane affects its movement in flight.
Parts of an Airplane:
Propeller and Motor: produces thrust (forward movement) on airframe
Fuselage: body of an airplane
Wing/Airfoil: provides lift (allowing it to rise)
Aileron: use to turn
Flaps: increases lift
Elevator: controls pitch (pointing up and down) of aircraft
Tail: keeps the aircraft flying straight
Rudder: corrects Yaw (Changes left or right facing direction of an aircraft)
