• Dihedral brace

• Wing trim tape

Tools and Adhesives Needed

• 30-minute epoxy

• 6-minute epoxy

• Mixing stick

• Epoxy brush

• Masking tape

• Hobby knife w/#11 blade

• Rubbing alcohol

• Paper towels

• Wax paper

• Ruler

• Felt-tipped pen or pencil

• Medium sandpaper

Step 1. Locate the plywood wing joiner. Using the ruler,

determine the center of the wing joiner and mark it with a

felt-tipped pen or pencil.

Step 2. Trial fit the wing joiner into one of the wing panels. It

should insert smoothly up to the centerline marked in Step 1.

Now slide the other wing panel onto the wing joiner until the

wing panels meet. If the fit is overly tight, it may be necessary to

sand the wing joiner.

Note: The joiner is flat on one side and tapered on the

side that faces the leading edge of the wing.

Step 3. Place the wing on a large flat surface with the center of

both wing panels resting on the flat surface. Raise one wing tip

" from the surface (see illustration below). If necessary, sand

the wing joiner until this is achieved. There should be no gaps in

the wing center. Once you are satisfied with the fit, remove the

wing joiner from the wing panels.

Step 4. Mix approximately 1 ounce of 30-minute epoxy.

Note: It is extremely important to use plenty of epoxy

when joining the wing panels together. It will also

be helpful to use wax paper under the wing center

when epoxying the wing panels together.

Step 5. Use an epoxy brush or a scrap piece of wood, apply a

generous amount of epoxy into the wing dihedral cavity in one

wing panel.

Step 6. Coat one half of the wing joiner with epoxy up to the

line marked in Step 1. Install the epoxy coated side of the dihedral

brace into the wing panel cavity up to the centerline marked.
