Extreme Flight's aerobatic models are loosely based on real airplanes, with the designer allowing himself a number of modifications to create a model with a unique appearance and flight performance. In the lightweight construction, which is based on balsa and plywood parts, carbon and glass composite materials are used generously - and in the right places - to achieve high strength and stiffness of the kite at a minimum weight. The result is a robust model capable of handling a wide range of aerodynamic loads, yet light enough to achieve high performance.
The kit includes tuning winglets or Side Force Generators (SFG) increasing the effective side surface of the model, making knife flight and other turns depending on the "authority" of the rudder easier and more stable. These winglets also make the model more stable during high angle of attack (harrier) turns. We highly recommend that you mount them on your model and experiment with them.
The perfectly sprayed laminate engine cover and aerodynamic wheel covers, as well as the option to choose from several color schemes of the ULTRACOTE (=Oracover) high-visibility iron-on foil cover, will give you a model that you will be rightly proud of at the airport. The combination of all these modern elements creates a model that pushes the boundaries of modern aerobatic flying. Extreme Flight models excel in all modes of modern aerobatics including slow 3D low altitude aerobatics, fast and aggressive extreme aerobatics and classic precision aerobatics.
Sports semi-model of a German aerobatic aircraft powered by a 150-180 cc gasoline engine for experienced pilots to fly classic precision and extreme 3D acrobatics.
The fuselage of the model is a classic construction of plywood and balsa laser cut parts with composite reinforcements with a removable laminate engine cover and a removable upper fuselage with a cabin (with an aluminum quick-release system) for perfect access to the propulsion system and RC equipment. The motor is mounted on a plywood box bed.
The two-piece wing with a symmetrical profile (the halves are slid from the side onto a carbon tube coupling and secured with an aluminum quick-release system) is also a classic construction with an all-balsa hard cover. Large area ailerons are controlled by 2 or 3 independent servos.
The tail surfaces are lightweight all-balsa construction, the VOP is two-piece with the stabilizer halves slid onto the carbon tube and secured by an aluminum quick-release system. The elevator halves are controlled by servos stored in the horizontal stabilizer with short straight rods. The moving part of the steering wheel can be dismantled for easier transport. The entire model is coated with ULTRACOTE iron-on foil (this is the brand name used in the USA for the well-known Oracover foils).
The chassis is a spur type with carbon main legs, wheels with laminate covers and a wire spur with a carbon bracket mated to the turn signal.
You will need a 150-180 cc petrol engine (e.g. GP 178) for propulsion.
The servos are fast and very strong in standard size (better quality, stronger and faster ones are suitable for using the potential of the model) and one standard servo for throttle control.
The kit includes: iron-on foil covered fuselage, wing and tail surfaces, sprayed laminate engine cover, complete set of accessories, carbon undercarriage, spur and wheels.
