07/02/19: Update of extended wingtips for increased stability during bank turns. Added tail file to create a non-motorized wing for gliding flight (not tried in flight yet). This model is an RC flying wing resembling a seagull. The bird flies very well and should work well in glider flight, it's powered by a small Emax 1306 motor with a 3S 350mah battery. Two 8g servos and a small receiver are sufficient for reception. Centered at 11cm from the leading edge at the wing root. The fuselage impression is done without special precautions. However, it's better to use the 3mf file for the wings since Cura will automatically print the ribs (filling by lines every 5cm), and the rest is in monoplane mode with a 0.4 nozzle. The filling should be done at a slow speed of 10mm/s to have solid ribs. Cura must force the printing of fine walls, the trailing edge is very thin, which will require some sanding for a smooth finish. Next model I won't get caught again, I'll give a thickness to the trailing edge. Everything is printed in PLA. A small carbon key joins the wings. Everything is glued with cyanoacrylate glue. The originality is that the servos are not in the wings but in the fuselage, so there's more space. Commands are made like a hand launch with a simple wire and a recall spring. The wire guidance is drawn on the wings). Attention: small design problem, it's impossible to screw the motor once the fuselage is assembled: you have to either screw the motor before gluing the two parts of the fuselage or do as I did: glue the motor with cyano (be careful with the bearings). https://youtu.be/VOKpCqu3wUE
