Additional items needed

Build instructions

  1. Trim off the top front edge of the shucks and tape together. Hot glue on the tape helps hold.
  2. All gluing and laminating must be done while the wing is resting in the schuck.
     
  3. Insert 5mm leading edge spars. Leave gap at wing tip.
  4. Insert 4mm aft wing spar.
  5. Join wing halves with 6mm center spar.
  6. Glue wing halves with hot glue at the top and bottom of the bay.
  7. Do not install 3mm elevon spars yet. They will be installed with hot glue next.
  8. Set wings on shucks, then add weights to hold wings perfectly flat.
  9. Drip medium CA into spar grooves, then spray with CA activator.
  10. Insert the elevon spars into the spar grooves, centered with even gaps on both ends.
  11. Do not glue with CA. Apply a generous line of hot glue on top of the elevon spar. You will melt down the line of glue with your film covering iron in a later step.
  12. Center the servo arm on the servo using your RC transmitter and receiver or a servo centering tool..
  13. Hot glue the servos in place as shown.
  14. Push the servo arm down flush with the top of the wing so it won't interfere with the laminate.
  15. Use a putty knife to spread a very thin layer of hot glue where shaded on the top and bottom of the wing. This insures the laminate won't come loose, stiffens the elevons, and creates a strong bond for the coroplast bay cover which is glued on top of the laminate.
  16. Install the precut laminate elevon strips on the bottom . Make sure wing is resting in the shucks on a level surface. Use your film iron on top of the laminate to melt the hot glue and make the elevon perfectly flat.
  17. There should be an 1/8" all the way around.
  18. Install wing bottom laminate. There should be a 1/8" gap at the red line.
  19. Overlap leading edge 1/2".
  20. Keep wing in shuck while installing with film iron. Do both sides.
  21. Install wing top laminate. Align servo and control horn cut outs.
  22. 1/2" overlap on leading and trailing edges.
  23. Antenna should be installed.
