A Speed 400 sized pylon racer / speed model I have been working on. It has not flown yet. Wing Span 720mm Length: 550mm Tail: 200mm Print Instructions (MUST READ): All the fuselage parts are SOLID so you must print with 0% infill! All settings below are in Simplify 3D. All parts printed in PLA. Fuselage Nose: Orientation: Set it motor mount face down, Length ( Print Height) = 180mm Base layers: 12 (or more for a thick strong motor mount. Outline / Permieter Shells: 2 Top Layers :0 Infill : 0% Support Structure: NO Motor mounting holes: These are under sized so you can drill them to the correct size. I went with 10mm for the centre hole and 3mm for the screw holes. Fuselage Mid Section: Orientation: Set it front face down (front or nose end of the model) Length ( Print Height) = 180mm Base layers: 4 Outline / Permieter Shells: 2 Top Layers :0 Infill : 0% Support Structure: NO Fuselage Tail Section: Orientation: Set it front face down (front or nose end of the model) Length ( Print Height) = 190mm (I had to scale the Z axis down so it was 180mm or less) Base layers: 4 Outline / Permieter Shells: 2 Top Layers :0 Infill : 0% Support Structure: NO Horizontal Stabilizer: Orientation: Set it top down so the control horn is pointing up. Width = 200mm Infill : 20% (or what ever you think is best) Support Structure: doesn't matter The elevator is printed with a live hinge, if you find this to stiff cut it off and hinge with tape. Vertical Stabilizer: The one pictured is to small. I modified it to make it bigger. Infill : 50% (or what ever you think is best) Wing Section: This was never meant to be printed it's just for show. Mine will be carved out of solid balsa as per the pics. Print it if you like, spar / joiner hole is 4mm.
