the wing. Trace the plate onto the wing with a felt-tip pen. Cut
the covering away in the area where the plate will be (see
Expert Tip that follows).
Be careful not to cut into the wood.
This will weaken the structure. Glue the wing hold down
plate to the wing with 6-minute epoxy.
❏
8. Once the glue has cured, drill a 1/4" [6mm] hole
through the holes in the top of the wing, drilling through the
wing hold down plate.
❏
9. On the top and bottom of the wing, cut the covering
away 1/8" [3mm] from the end of the wing tip, being careful
not to cut through the balsa wing skin.
❏
10. Locate the right wing tip. (When installed on the wing
the curve on the wing tip will be turned up). With 220-grit
sandpaper, roughen the inside of the tip where it will make
contact with the wing and then wipe the area with rubbing
alcohol.
❏ ❏
11. Glue the tip to the wing with 6-minute epoxy.
Repeat this step for the left wing tip.
Set the wing aside and begin the fuselage. You will come
back to the wing and install the landing gear later in the
instructions.

1. Examine the fiberglass fuselage. At the rear of the
fuselage there are three molded pushrod exits. A 3/16"
[4.8mm] hole needs to be drilled through each of them. You
must follow this procedure! If you try to drill a single 3/16"
[4.8mm] hole the drill
will tear the fiberglass. Start by drilling
a 1/8" [3mm] hole followed by a 5/32" [4mm] hole and then
a 3/16" [4.8mm] hole. Another method that works very well
is to make the hole with a high-speed rotary tool and a small
grinding bit. This would be the preferred method because
there is almost no likelihood of splitting the fiberglass.
❏
2. Locate three 24" [610mm] gray outer plastic pushrod
guide tubes. Cut the tubes to a length of 18" [457mm].
Roughen both ends of each tube with 220-grit sandpaper.
Insert the tubes into the holes you drilled, feeding them
through the holes in the rear bulkhead inside of the
fuselage.
❏
3. Glue each of the tubes into the holes using 6-minute
epoxy. Be sure you have roughened the tubes before gluing
them into position.

HOW TO CUT COVERING FROM BALSA
Use a soldering iron to cut the covering. The tip of the
soldering iron doesn’t have to be sharp, but a fine tip does
work best. Allow the iron to heat fully. Use a straightedge
to guide the soldering iron at a rate that will just melt the
covering and not burn into the wood. The hotter the
soldering iron, the faster it must travel to melt a fine cut.
Peel off the covering.
