The MULTIPLEX Challenger is the perfect introduction to the world of 3D aerobatics. The two large wings and the high fuselage allow a low airspeed in all flight attitudes. The large rudder surfaces provide the necessary maneuverability. It is therefore equally suitable for beginners and professionals. A “must have” for all biplane and 3D aerobatic fans. The EPP model is very robust and forgives almost every mistake. All imaginable aerobatic maneuvers are possible with the model.
