91 "Extra 300 V2 EXP - Green 2.31m

The aerobatic models of Extreme Flight are loosely based on real aircraft, while the designer allowed himself a number of modifications to create a model with a unique look and flight performance. The designation EXP has nothing to do with the actual aircraft, but is an abbreviation of the words "Experimental Progressive". This designation was chosen because the Extreme Flight models use several advanced design and aerodynamic concepts. In the lightweight construction, which is based on balsa and plywood parts, carbon and glass composite materials are generously used - and in the right places - to achieve high strength and rigidity of the kite at minimum weight. The result is a robust model capable of handling aerodynamic loads over a wide range, but light enough to achieve high performance.

The kit includes tuning winglets or Side Force Generators (SFG) that increase the effective side area of the model, making blade flight and other turnaround-dependent turns easier and more stable. These winglets also make the model more stable at high angle turns. We strongly recommend that you mount them on a model and experiment with them.

Perfectly sprayed laminate engine cover and aerodynamic wheel covers as well as the possibility to choose from several color schemes of the ULTRACOTE (= Oracover) ironing foil cover with high visibility will provide you with 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 acrobatic flying. Extreme Flight models excel in all modes of modern aerial acrobatics, including slow 3D acrobatics at low altitude, fast and aggressive extreme acrobatics and classic precision 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 part of the fuselage with a cabin for perfect access to the propulsion system and RC equipment. The motor is mounted in the rear mounting on plywood box beds; a tunnel on the underside of the fuselage is prepared for possible installation of a tuned muffler.

The two-part sash with a symmetrical profile (the halves slide from the side onto the carbon pipe coupling and secure with screws) is also a classic construction with an all-balsa rigid coating. The ailerons with a large area are controlled by 2 independent servos. You can provide the wing ends with the supplied winglets.

The tail surfaces are light all-balsa constructions, the GTC are two-part by stabilizer halves pushed onto the carbon tube. The halves of the elevator are controlled by servos mounted in a horizontal stabilizer with short straight rods; the rudder is controlled by cable drives by a servo stored in the cabin space. The entire model is covered with ULTRACOTE iron-on foil (this is the trademark used in the USA for the well-known Oracover foils).

The chassis is of the spur type with carbon main legs, wheels with laminate covers and a wire spur with a carbon bracket coupled to the rudder.

For the drive you will need a petrol engine 60-70 ccm (eg GP-61, OS GT-60) or an AC electric motor 6 kW (eg Xpwr 60cc) with at least 160 A speed controller powered by a 12S LiPo battery 5000-6000 mAh with a load capacity at least 40C.

At least a seven-channel computer RC kit is suitable for controlling the model - the possibility of precise setting of "pair" servos and programming of double and exponential deflections in the correct size is essential for flying acrobatics - classic accurate and extreme 3D.

Servos suit fast and very strong in standard size - e.g. Hitec Hitec HS-7950TH, D980TW or HSB-9381TH and one standard servo for throttle control.

The kit includes: iron-on foil coated fuselage, wing and tail surfaces, sprayed laminate engine cover, complete set of accessories, carbon chassis, spur, wheels and instructions.
