NOTE: Do not use too much pressure with the sanding block or you risk tearing instead

of sanding.

15. Perform a final sanding of the entire wing with a sanding block and 120-150 grit

sand paper. This sanding will help remove the thin layer of heat-affected EPP from the

hotwire process, which will help the lamination film better adhere to the surface of the

foam.

16. Now is also the best time to sand and bevel your balsa elevons in order to reduce

dust/debris on the bench during covering.

Wing Covering

17. Once you are satisfied with the wing's finish it is time again to vacuum the wing,

elevons and beds to make sure they are free of any debris. Also make sure the bench is

free of any dirt/debris, as the laminating film likes to attract anything you miss.

18. Using one of the wing beds as a template, cut out four pieces of 5 mil lamination

film. Make sure to cut the pieces long enough to overlap in the center of the wing.

19. With the wing facing bottom-up in the top beds position a piece of the laminating

film over half the wing. There should be a few inches of overlap in the center. Use a

medium-hi covering iron and start in the center of the panel and work out to the tip.

Then work from the center of the panel to the center of the wing. Repeat for other side.

NOTE: 5 mil lamination film will not stretch as much as some iron-on coverings. It does

not wrinkle as easily, but if you start a wrinkle it is harder to iron out. Keep the covering

tight with your free hand and avoid too much slack as you iron down the covering.

Practicing with a small scrap of film on the foam beds is recommended. When the film

goes clear under the heated covering iron you have reached the right temperature.

20. Once the bottom of the wing is covered you can place the wing in the bottom beds

with the wing facing up and repeat the same process for the upper surface.

NOTE: For best performance it is critical you do not impart a twist/warp in the wing

while covering. Keep the wing flat in the beds as much as possible while covering; take

your time; and attempt to use the same technique and heat for all four panels.

Elevon Installation

21. Once the wing is covered you can cover and install the elevons. The elevons can be

covered with the provided 1.7mil lamination film or your preferred tape. Whichever

method you prefer, it is important that the elevons are flat after covering.

22. You can use either tape or lamination film for the hinge. We prefer the 1.7mil

lamination film, but a tape such as 3M Blenderm will work.
