Kavan FunStik #KAV02.8036
The hull has a classic balsa and lightweight plywood construction. Its backbone is the lower balsa sheet with laser cut grooves into which you gradually insert all the frames, bulkheads and side panels. The combustion engine is attached to the plastic bed on the plywood engine bulkhead. The rear-mounted electric motor is just as easy to mount. The location for rudder, elevator and throttle servos is in the fuselage under the wing. A removable cover on the top then allows access to the fuel tank or the insertion of a drive battery.
The one-piece wing with a symmetrical profile has a classic construction with balsa ribs and a fixed planking of the D-Box. It is attached to the hull with two plastic screws. Again, construction is made easier by using laser-cut pieces with puzzle-style indentations and bulges. This allows you to assemble everything correctly and not twisted, without the need for construction jigs. The full span ailerons are controlled by two micro servos with short direct wire linkages. The wing design allows the linkage and aileron levers to be mounted on the underside of the wing (suitable for flights with landing gear) or on the top of the wing (suitable for flights without landing gear with belly landings in grass).
The flat tailplanes are glued from spruce spars and laser-cut balsa parts. The rudder and elevator are controlled by servos placed in the fuselage under the wing with bowden cables.
The landing gear with a fixed spur is made of Dural, with lightweight KAVAN wheels.
To control the model you need at least a 4-channel RC set. Normal servos with an actuating force of 3-4 kg.cm are suitable for the rudder and elevator. To reduce the weight of the electrojet, you can mount mini or micro servos with similar parameters. Use high quality micro servos for aileron and throttle.
To drive the model, you can choose ordinary two-stroke engines with a 3.5-4.0 cc glow plug and 100-150 ml tank. If you are looking for more powerful O.S. MAX-25FX II, a 150-170ml tank is preferable.
In the electric version you can mount a 500-600 W brushless electric motor, for example KAVAN C3542-1200 or Model Motors AXI 2820/10 V2 with a 10x6-8" propeller, 50-60A ESC and 3S LiPo battery 2200- 2600mAh.
The kit includes: laser-cut balsa and plywood parts, spruce spars, balsa spars and boards for fixed planking, an accessory kit, Dural landing gear, lightweight wheels, a sheet of self-adhesive decals, a blueprint and instructions.
