The Extra 300S has won the World Aerobatic Championship many times. The full size version flies aerobatics at 300km/h. Ultrafly’s Extra is naturally slower but is engineered to perform equally thrilling maneuvers!
This quality foam construction Extra 300S is the first small, scale-like model able to perform flat spin, knife edge and many other difficult aerobatics using its stock Falcon 400 motor and 3:1 gearbox. Install the Ultra Fly A/30/29kv brushless motor and it becomes an unlimited aerobatic competition plane capable of even the most difficult maneuvers.
