CARF KOBUZ-3 3m 403000
The cooperation between Ceflix, PS-Models and CARF-Models is not new to our customers and where all these impressive airplanes are made is a very open secret... So it was a natural development that CARF-Models soon would also help distributing the smaller line of extremely powerful scale gliders as seen in Ceflix' and PS-Models product catalogue. As a result the smaller line of gliders is now available at CARF-Models, too. It got the CARF treatment in terms of prefabrication and detail improvements and adjustments for the international markets and HERE IT IS: The CARF-Models Kobuz-3 3m! It introduces a performance never seen before.
It's the epitome of a painted in the mold, all carbon, scale, ultra performance acrobatic glider with only the best materials and components used. Not too big, so that it's still easy to transport and store, but also has already a huge potential for the aerobatic maneuvers in the glider mode. Also perfectly suited for awesome but still economical 60-70N turbine as well as electric power with the commercially available retractable EDFs or various FES. Breath-taking in any version, simply the BEST on the market for the thrills of flying high performance powered gliders.
Composite High End Construction
The fuselage is all carbon in all the load carrying areas, only the front part of the fuselage under the canopy is fiberglass, as we needed to make sure the RC-Equipment will work properly. Dual layers of 45 degree carbon, longitudinal unidirectional reinforcements make the fuselage safe for 400+ km/h dives. The smoked canopy is finished, fitted to the frame, which has been painted in the factory. Pins and tabs to secure it to the fuselage are also factory installed.
The Wings are also completely made from carbon fibre. Multi layers of carbon in the skin wrap around an incredibly strong main spar. Control surfaces are hinged and a sealing lip is factory installed. Control horns, servo mounts, hatches, linkages are all pre-built. For the Flaps high end 15 mm servos are used, for the ailerons 11-12 mm servos. We recommend our MacGregor MAC5216 and MAC2611 as the best, most powerful and most reliable option.
A solid 20 x 35 mm cross sectioned carbon wing joiner carries the flying loads as a "floating spar", whereas the wings are joined to the fuselage with 4 8mm carbon pins and 2 M6 knurled nuts.
The horizontal stab is also a full carbon design with elevator pre hinged on elastic hinge, sealed with composite lips. It is removable with one single bolt, automatically disengaging the massive control horn when removed. The rudder is attached with a steel pin to 2 carbon hinge posts in the fin, solidly glued into a plywood spar. A pull/pull setup connects it to the rudder servo installed right behind the landing gear.
Of course, all control horns, hinge posts, pins, dowels, servo hatches, are factory installed.
Propulsion and Performance
The CARF-Models KOBUZ-3 can be flown in the mountains (slope soaring), it can be aero-towed for scale glider aerobatic performance and it can be propelled by a 60-70 N jet engine, a retractable electric ducted fan or an FES (electric front motor with folding prop). The truth of the matter is more like that it can be banged around so that "gliding" becomes an unnecessary flight stage, except for landing...
Lets speak about roll rate. How does 720 deg/s sound? Rifle Rolls with a glider? No problem. Let it go around corners with 15 G or more. If you see the wings bend, your heart might stop for a second, especially when you tried bending them with your hands before and realized how rock hard they are. Hell yeah, you see them bend due to aileron input alone, right wing positive, left wing negative, when you roll left, and vice versa. And the engine shut-down Pop-Top when you've got enough, is a must, too. Then glide a few rounds, calm your nerves and touch down with the help of the ultra effective flap and aileron crow.
The KOBUZ-3 is literally unbreakable in the air, with all the carbon used in the construction. It is 450+ km/h safe, it can be pulled up at full throttle without regrets. It is not only a high performance glider, it is also a powered speed plane to be enjoyed low and fast, Reno-style.
And at the same time it is docile, slow, predictable when needed. It can be flown on small airfields, grass runways, in the wilderness of breath-taking mountains, as well as on asphalt airfields. The CARF-Models KOBUZ 3m is a kind of its own. Raw, powerful, elegant and sexy.
