Project Title: Vintage electric motor pylon for WIK Modelle Condor 3300 RC sailplane Design a fully parametric 3D printable motor pylon for a vintage RC sailplane. The design must look like an original accessory from the late 1970s–1980s, matching the style of the WIK Modelle Condor glider. The pylon must be elegant, aerodynamic, and lightweight while maintaining structural strength. Aircraft WIK Modelle Condor Wingspan: 3300 mm Flying weight: 2100–2500 g Vintage fiberglass fuselage Installation on top of the fuselage behind the canopy Base Length: 180 mm Width: 79 mm Curved bottom matching a rounded fiberglass fuselage Thickness: 4 mm Large fillets between base and fin. Four M4 mounting holes. Counterplate included. M4 brass heat inserts. Fin Height: 175 mm Root chord: 120 mm Tip chord: 70 mm Symmetrical NACA 0012 airfoil Maximum thickness: 18 mm Smooth leading edge Sharp trailing edge Internal hollow construction. Four longitudinal spars. Eight internal ribs. Shell thickness: 2.4 mm No unnecessary weight. Estimated printed weight: 100–115 grams. Material: PA6-CF (carbon fiber nylon) Motor mount Brushless motor: 35 mm diameter 48 mm length 800–900 KV Support removable. Standard X-Mount. Support hole spacing: 19 × 19 mm 25 × 25 mm Center hole: 25 mm Motor offset: 2° down 2° right Motor located close to leading edge. Cooling Internal cooling duct. Front air inlet. Rear outlet. Motor wires routed internally. Hidden cable exit. Propeller 13×8 folding propeller. Spinner: 40–42 mm. Enough clearance above fuselage. No interference with canopy. Structure Design for high stiffness. Internal ribs connected to spars. Reinforced motor area. Reinforced base. No sharp stress concentrations. Rounded transitions. Printing Optimized for FDM. Bambu Lab printer. PA6-CF. 0.4 mm nozzle. Supports minimized. Single printable parts. Motor mount removable. Counterplate printable separately. Style The design must NOT look modern F5J. It must resemble an original vintage WIK accessory. Rounded lines. Organic transitions. No aggressive shapes. Elegant. Classic. Timeless. White painted finish. Looks factory made.
