To build wing for Blaster 3, we use bi-axial carbon Spread Tow fabric of our own proprietary design and production, made of high strength IMS65 carbon fibers. The weight of this fabric is 38…40 gram/m², which leads to lighter and stronger parts.

The wing design provides a unique combination of high stiffness and strength with the minimum weight.

The wing spar of Blaster 3 consists of two flanges and the web. The flanges are made of high modulus unidirectional carbon fiber located near the wing outer surface. The web consists of the light weight styrofoam inside a braided CF sleeve, which ensures +45/-45 degree fiber orientation increasing the web strength.

The wing skins are made of Rohacell foam and glass cloth. Ailerons are very light and stiff due to the braided CF sleeve spar. Such design also moves the aileron C.G. forward, preventing flatter at high flight speeds.

Fuselage

The fuselage Blaster 3 represents a seamless carbon construction and radio transparent kevlar nose cone. The fuselage of the most collected. You just have to glue the servos, rudder and to rods.

Tail boom

For the first time, the fuselage does not consist of a separate nose and tail boom. The unique single piece design saves the weight while yielding a stronger structure. The new full length CF tube transfers the load of the ground impact without stressing the nose cone. The wing is attached directly to this tube.

New wing mount

The new wing mount employs the cone shaped mating surfaces, which securely locks the wing on the fuselage even with lightly torqued fasteners. In addition to that, the high stresses of the launch are spread over the large cone surface instead of crush prone bolt holes. The main front mount is made from a high strength carbon fiber with an embedded aluminum washer.

Pylon

The front cross-section of the wing pylon, where the nose cone slides on, is non-circular. This prevents the nose cone twisting by wind gusts, while you are holding the plane by its nose. Inside the pylon comfortably accommodate a receiver, or battery, depending on the chosen center of gravity.

Convenient access

With the nose cone removed, you have an unobstructed access to all the RC gear. This greatly reduces the complexity of the servo and battery mounting, when you are building the glider.

Ballast provisions

The design offers well thought provisions for extra ballast. Inside the fuselage tube just under the RX, there is a special ballast fixing part, which adds only 0.6 g (0.02 oz) to the total weight.
