Richard VanGrunsven the early 70s decided to construct an acrobatic dolnplosník that he could build every home in the garage. That he succeeded perfectly machine RV-3, in the late '70s was followed by two-seat RV-fourth Since then, the company Van's Aircraft has supplied thousands of sets of plans and kits; It is estimated that in the 45 countries was completed and flew over 8000 machines from their kits and thousands more are in the works. If you do not have 17,800 US dollars per kit genuine RV-4, you can try to build at least a mock-up of the Great Planes ...
Designers American amateur two-seat aerobatic plane classic balsa structure in Rozsyp to drive 6.5-8.5 cc two-stroke engine or a four stroke 8-11,5 cc. Given the favorable ratio of the weight of the airframe and the supporting surface is suitable for conversion to electric drive motor class AXI 2826 to 4120. RV-40 is an ideal project for modelers who already has experience in building simple models in Rozsyp (such as. ElectriCub, Piper 1: 6, etc.) and reliably handles a monoplane flying with controlled ailerons. A sophisticated "interlocking" construction with components provided with protrusions and indentations that fit together like a jigsaw puzzle parts, construction goes very quickly and easily.
The fuselage is a classic design of lightweight balsa and plywood; its "core consists of a simple" bedničková "construction with balsa side panels and plywood bulkheads, which is then supplemented shaped polopřepážkami and balsa cover. You easily get fixed and uncurled design reproducing the shape of the actual machine. The engine is mounted on adjustable plastic bed on a plywood partition with his head to the side, a plastic engine cover. Space for servo rudder, elevator and gas is located in the fuselage above the wing.
One-piece wing is symmetrical profile is a classic design with balsa ribs and rigid torsion box cover. The ailerons and flaps are controlled by a pair of servos located in the wing using the short straight rods.
The tail surfaces are plate, glued from balsa wood beams.
Chassis with steerable wire spur coupled with the rudder is duralumin.
The model can drag the iron sheeting - Oracover or MonoKote are ideal for this purpose.
To control model you will need at least four channel radio system, if you build a model without controlled dampers. When you install the shutters using at least six or sedmikanálovou RC kit. Serva meet the normal standard of stroke 3-4 kg.cm.
Kit contains: předseknuté balsa and plywood parts, balsa wood beams and boards on a rigid cover, a plastic engine cover and cab plastic Scale details, accessory kit, adjustable motor mount, wired chassis, sheet self-adhesive decals, construction plan in scale 1: 1 instruction .
