The model was constructed on a scale of 1: 4 so that retractable landing gear and airbrakes could also be installed. Our four-stroke engines are primarily intended as the motorization - single-cylinder Saito FA-56, 65, 72, 80 and 91 or boxer engines FA 90 TS and FA 100 T. For all single-cylinders, our vibration-damping engine mount, Order No. 7153/11, is used. Installation of an electric drive is also possible - e.g. our actro 24-5 with a CAM Prop 14 x 8 ″ or 14 x 9 ″ and 16 cells. In terms of aviation, our RF - 4D is a delicacy. The wing has both aerodynamic and geometric twist, which, in conjunction with a very low wing loading, ensures excellent, balanced flight behavior. It deserves to be flown “Scale”, for the eyes and the heart! Radiant elegance, especially at lower altitudes, flight style - leisurely to quite brisk. A moderate aerobatics “classic” is possible. Loopings flown with feeling, effective turns, rolls or the like are no problem. Since most of the time you fly with the engine throttled, the fuel consumption is minimal. Long approaches can be divided precisely with the help of the airbrakes. The wing is in two parts, the 18mm connector forms a duraluminium tube of the highest strength, the horizontal stabilizer is firmly glued to the fuselage (via carbon tubes). Access to the RC equipment is ensured by a large recess on the bottom of the fuselage. The wing lock can also be reached here. The GRP fuselage is of the high quality that aero-naut is accustomed to, with molded root ribs for the wings and CPR, the fin is already molded, all necessary implementations as well. The horizontally divided, two-part GRP engine hood already has guides for centering both parts. The cockpit equipment is based on the original, these parts are made of ABS plastic. The assembly instructions give further tips on how to design the interior (e.g. upholstery). The retractable undercarriage, sprung, with hollow rubber tires diameter 95mm was specially developed for this model. The sheet metal parts made of duraluminium or steel are precisely manufactured with a computer-controlled water jet, various points are brazed and powder-coated. It retracts into an ABS fender built into the fuselage. Pneumatic EZFW control with its compressed air cylinder of 18mm diameter (bore) is designed as single-acting. This is an important contribution to safety, because if there is a loss of pressure in the system, the landing gear is automatically extended! Also included is an adjustable pressure reducer, which can be used to set the timing of the retraction or extension “scale”. The control valve is also designed to be single-acting; it is actuated by pressing a cam (cam) mounted on the (mini) servo, for example, and a spiral spring is used to extend it. Only the hand pump with manometer (e.g. Robart) has to be bought. The model kit contains: detailed construction instructions with photos of the construction stages, construction plan with RC installation, GRP fuselage and bonnet, wings in Styro - Abachi, CPR in Styro - balsa construction, airbrakes, spinner, retractable undercarriage and support undercarriages, spur, exhaust and filling props mock-ups, Canopy, ABS parts, CNC milled parts made of plywood and GRP, stamped parts, Duralumin tube diameter 18 / 16mm GRP tube (guidance of the connection), wing locking, identification of the prototype - plotted, with transfer film, set of small parts. Motorization Due to the favorable aerodynamic design, especially wing loading and high aspect ratio, our RF-4D is ideally suited for electric drives. When installing the motor, our rubber buffers, order no. 7002/75, can be integrated. The flight battery should be two-part (2 x 8 cells), the batteries protrude into the engine compartment (bonnet) (center of gravity!). Installation of internal combustion engines Engine noise is also part of a powered aircraft and the flight experience. With a scale model, the noise should also be scale so that the flight image appears balanced. In short ? The RF-4D has a four-stroke engine. We recommend our engine mount 7153/11 with vibration rubbers, which holds all single-cylinder engines. It reduces the transmission of engine vibrations to the cell and among other things reduces the noise emitted by the cell. Even with the Saito FA-56 with 9.1 ccm, the model is good, scale motorized. All Saito FA 56 up to the FA 91S with 15 ccm can be installed. The Saito FA-90TS boxer engines with 15 cc and the FA-100T with 16.4 cc are of course ideally suited. In order to increase the safety of flight operations, we recommend the installation of a glow regulator, the market offers a large selection. Another advantage: there is no need for a starter battery (and the ugly hole for the spark plug connector). By the way - all of the engines mentioned disappear completely under the bonnet! which accommodates all single-cylinder engines provided.
