A High-Performance Pylon Racer/Speed Model I've Been Working On Has Not Yet Taken to the Skies. Wing Span: 720 Millimeters Length: 550 Millimeters Tail Length: 200 Millimeters Print Instructions (Mandatory Reading): All fuselage parts are solid, so you must print them with zero percent infill. All settings below are in Simplify 3D. All parts were printed in PLA. Fuselage Nose: Orientation: Set the motor mount face down. Length (Print Height): 180 Millimeters Base Layers: 12 (or more for a robust motor mount) Outline/Perimeter Shells: 2 Top Layers: 0 Infill: 0% Support Structure: No Motor Mounting Holes: These are undersized, so you can drill them to the correct size. I chose 10 Millimeters for the center hole and 3 Millimeters for the screw holes. Fuselage Mid Section: Orientation: Set it face down (front or nose end of the model). Length (Print Height): 180 Millimeters Base Layers: 4 Outline/Perimeter Shells: 2 Top Layers: 0 Infill: 0% Support Structure: No Fuselage Tail Section: Orientation: Set it face down (front or nose end of the model). Length (Print Height): 190 Millimeters (I had to scale the Z-axis down to 180 Millimeters or less) Base Layers: 4 Outline/Perimeter Shells: 2 Top Layers: 0 Infill: 0% Support Structure: No Horizontal Stabilizer: Orientation: Set it top down so the control horn points up. Width: 200 Millimeters Infill: 20% (or whatever you think is best) Support Structure: Doesn't Matter The elevator was printed with a live hinge. If you find this too stiff, cut it off and hinge it with tape. Vertical Stabilizer: The one pictured is too small. I modified it to make it bigger. Infill: 50% (or whatever 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 pictures. Print it if you like, with a spar/joiner hole of 4 Millimeters.
