Piranha

thingiverse

The Piranha is a fast yet easy to fly small sports plane with retractable landing gear. The original model was available in the late 70s as a kit with a glass fibre fuselage and foam core wings. It was designed around the Webra Speedy 15 2-stroke engine (1.8 ccm) including resonance silencer. The 3d printable replica is designed for a brushless motor and a 3 cell lipo battery and sculpted after the original plan. The size fuselage cross sections and used Airfoils are identical to the original. You can download a free section of the fuselage and the wing to test your print settings. Both parts need no support and no infill.
