3d models for attaching a foam wing to your quadcopter. Do your aerodynamic research! I used the very popular 17.5foam wing (about $20 on amazon for styrofoam plane). For assembly, you will need M3 16mm screws and nuts. I applied different wing angle settings to the assembly: from 50 degrees to 30 degrees in 2.5 degree increments (leg* ). The wing installation angle is taken from the horizontal hover plane of the quadcopter in calm weather. I recommend flying in calm or upwind (or downwind). Also, depending on the flight mode, you will (probably) need to trim the wing. In the event of a crosswind or incorrect wing installation, you will see something like aDutch pitch" or other interesting effects. There are no front legs in the assembly, so I started the copter from the hand. Be careful!
