BUILDING INSTRUCTIONS

Assemble the Wing

Note: Accurate assembly of the wing is critical. In addition

to your first cursory reading, please read all steps in this

section carefully prior to beginning wing assembly.

1. Test fit the wing joiner into the slots in the wing halves.

Sand the joiners as required to get a tight, secure fit that

allows the wing panels to mate as nicely as possible. NOTE:

If the root ribs' angles aren't exactly the same, that's ok. The

difference can be filled with epoxy when the wings are joined.

The proper dihedral angle and the gluing of the wing joiner is

far more important than the mating of the two wing panels.

2. Cover your workbench with wax paper.

3. With the left wing flat on your workbench and the

center joint on the wax paper, raise the right wing 6-1/4"

[160mm] to properly set the dihedral. Block the raised right

wing at the desired height and make a mental note of the

position needed for it to maintain that dihedral. Slide the left

wing and joiner off the right wing.

4. Remove the joiner from the left wing. Cover the joiner,

left and right wing ribs and pockets in the wing panels with

a moderate but not excessive amount of 30-minute epoxy.

Join the wing halves together. Ensure that the left wing

remains flat and the right wing tip is 6-1/4" [160mm] from

your work bench and can remain that way undisturbed for at

least 4 hours, preferably overnight. HINT: Use masking tape

to hold the wing together while the epoxy hardens. Remove

any excess epoxy with a paper towel and denatured alcohol,

being careful not to disturb the joint.

5. Glue the plastic TE support centered on the wing.

Assemble the Tail

1. Place the fuselage upside-down on the workbench.

Drill a 1/16" [1.6mm] hole centered on and 1" [25mm] from

the end of the bottom of the fuselage.

2. Sand the area of the tail skid that contacts the fuse

with coarse sandpaper.

3. Cover the sanded area of the tail skid with epoxy and

glue the tail skid in place.
