Wing halves assembly
Roughen the main spar with a sandpaper, apply glue to one side of the spar and insert the spar into the
side of the wing. Roughen and cover the surfaces of the battery bay, adjoining foam faces and the spar on
the opposing side with PU glue, spray water to activate the glue. Insert battery bay into one of the wing
halves, align the other wing half on the wing spar and push the two together to form a solid wing. Use tape
to keep the two halves pressed together.
Motor mount
Assembly the four plywood pieces to form the motor mount assembly. Glue it in place at the rear end of
the wing, use CA or Epoxy. Make sure to add glue to all the sides that are exposed to the foam frame, as
this is a load-stressed area. It is possible to attach the motor after the motor mount has been installed.
