coating on the surfaces, allow some dry time, and then apply another light
coating, letting it evaporate a bit before bonding.
Spray the wing with 3M 77 and let it set for about 5 - 15 minutes, until it is tacky.
2.
Starting from the trailing edge, run a strip of tape across the length of the wing. The first
3.
strip should overhang the trailing edge by 1/2". Continue laying down strips of tape to
cover the bottom of your wings, overlapping each piece by 1/4". The tape should also
extend past the wingtip where you will wrap the tape around the tip before trimming.
Keeping your scissors or hobby knife clean is very important to the covering
process. After every five to ten cuts, wipe your blade with a Windex dampened
paper towel. The residue from the tape can make clean cuts almost impossible
since the tape will stick to the blades and just rip instead of cut.
Repeat Step 3 for the tops of your wings.

Smoothing out the Covering Tape (Optional)
Using a heat gun, you are can carefully shrink the tape until you get a glassy finish. This is
not a required step, but will make the surface look more polished. Be very careful as the
tape can shrink enough to pull away from the adjoining tape.
Start shrinking the bottom of the wings first, beginning at the leading edge and moving
1.
towards the trailing edge. Do the middle areas last.
Follow the heat gun's path using a covered hand (you can use a thick, clean sock or a
2.
towel), pressing down firmly, smoothing the surface and allowing the tape to adhere to
the adhesive.
Once the bottom is done, shrink the top in the same fashion.

Step 2: Assemble the Fuselage
You will assemble the fuselage by first gluing the two fuselage halves together, adding
strapping plastic for reinforcement, sanding to shape, adding servo mounting plates, then
taping the fuselage. Follow along carefully as there are a few critical steps along the way.

Take great care to keep the fuselage straight.
