Install the Winglets

  1. Insert the leading edge spar backwards so you can align the winglet.
  2. Apply hot glue the wing tip.
  3. Slide winglet over spar and align bottom edge, then firmly press together until hot glue cools. Do both sides.

Install the motor mount

  1. Glue the sides on with medium CA.
  2. Note: Rectangle opening goes on bottom.

  3. Glue the top and bottom with medium CA.
  4. Test fit the motor mount in the cut out in the rear of the plane.
  5. Apply medium CA to the motor mount where it will contact the plane. Do not us CA accelerator.
