Canard RC Airplane, Pusher

thingiverse

This is a canard that uses a printed body, fixed canard printed as part of the nose. It gives a 3-part fuselage and 5 joiners. I designed the canard/nose to be printed on my Anet A8 diagonally since maiden flights. Tapered wing tips have been added since then. The wing is made from foam in a stepped airfoil. The shapes for it to be cut will be included. I made the wing from MPF 6mm foam, and other foams could probably be substituted. It has a 40.5-inch span, an 11-inch center chord. The wingtips have a 4.25-inch chord; the wing tips are swept back 7.5 degrees. The elevons are 1.5 by 14 inches long. The CG is 3 inches behind the root chord. The wing has 1/4-inch wooden dowel leading edge spars for toughness and three 6mm carbon spars running spanwise at 1.75, 4, and 6 inches back from the center chord line. I used 12-gram metal gear servos at 7 inches out from the center line. It has twin vertical stabilizers glued to the wingtips. No stiffeners were added; if you substitute a softer foam, you might want to add a leading edge stiffener. The motor is a 3010c Turnigy motor on a pedestal mount with 1300kv and turns a thin 10x5 quad prop. It's powered by a 1600/4s battery and 40-amp speed control. Maiden flight can be watched here: https://www.youtube.com/watch?v=Tcwfs8ura78 Watch carefully as the launch happens; hold the front of the right wing and release it with your left hand. This motor is powerful enough to cause injury or death. I am not responsible for injuries; make at your own risk. It's recommended that only experienced pilots fly this plane.
