Semi historic gliders 3500 mm for thermal soaring. Design wing fuselage and tail surfaces, controlled ailerons, rudder, elevator and stop aero tow hook (already built into the bow).
One high-performance glider K8B German company Alexander Schleicher (construction Rudolf Kaiser - because it "K" on the label) belonged to the late fifties and during the 60th years among the world's most widely used types. It represents one of the highlights of the classic design from the days before the advent of super-composite materials and laminar proposed with the help of computers - the hull was welded from thin steel tubes and covered with canvas, wooden wing and tail surfaces were covered with plywood and canvas. Even without the composites but in 1968 one U.S. K8B set a world record in the target return flight with a length of 767 km. Were built over 1,100 pieces K8B in three versions; K8B design with an elegant piece "bubble" canopy improving the view from the cockpit was the largest.
Třiapůlmetrový K8B produced by Phoenix Model designed especially for aero-tow and thermic flying faithfully reproduces the shape of the actual machine and also takes into account the original design. The hull consists of lightweight construction of plywood and balsa wood bulkheads and stringers spruce and balsa wood covered with Oracover iron-on transfers. Access to the on-board electronics provides removable canopy - the clear "bubble" to find mock-up dashboard and pilot-printing is the concentrated expression of the stick when centering gliders in thermals. The bow is already built tow hook for aerotow.
Two-piece wing profile HQ/W-3/10 pushing the side of the coupling of two 10 mm stainless steel tubes is a classic design with torsion box with balsa solid coating and coated iron sheets Oracover. The ailerons are dominated by two servos with short straight rods; realistically thick airfoil with a domed central curve gives enough space to use standard size servos.
The tail surfaces in a classical arrangement are balsa, balsa horizontal stabilizer has a cover, the tail is again covered with Oracover. For easier transport are the horizontal and vertical tail removable, fastening screws. Rudder and elevator are controlled by wire rods standard size servos stored in the cockpit. Next The standard servo controls the tow hook formed by the guide tube glued to the bow and sliding cross pin.
The landing gear is as "adult" K8B consist of one unsprung around half protruding from the fuselage contour.
To control the model you need five standard servos - ailerons for a tow hook is enough common types of pulling 3 kg.cm, the tail is rather choose suitable servo to pull 5-6 kg.cm.
RC kit you need is a computer with six-channel mix Flaperon for aileron control a switch to control the tow hook.
Motorization model: K8B can easily "scale detail" to propel the engine mounted on a pylon above the fuselage - itself offers a simple solution naohýbat duralumin metal pylon in the shape of an inverted "U" tube clutch slipping on the wing. Enough power to ensure the combustion stroke of 6.5 cc or motor AXI class 4120th For "Non-scale Items" installation of the electric motor on the bow K8B is not suitable, it would require an almost complete reconstruction of the nose.
Kit includes: structural fuselage, wings and tail surfaces covered with Oracover, accessory kit, wheel and instructions.
