In this page we will see how to properly attach the wings. Check out the video above for a visual reference.
Slide the rod into one wing, and then the other.
Connect the servo wires to the splitter originating from main out channel one on the Pixhawk, either wing can go into either side of the splitter.
Fit the wings into the body, avoid squeezing the servo wires in between the wings and the body.
Attach two rubber bands.
After finishing the Wing Assembly process move on to Installing The Propeller.
