Install The Engines & Fuel Tanks; Install The Canopy - GREAT PLANES Profile 38 Instruction Manual

Install the Engines & Fuel Tanks
1. Reinstall the engines. Remember that the mounting
screws are installed from the back and that the lock washer
and nut are on the engine side. Use threadlocker on the
engine mounting screws to prevent them from coming loose
from engine vibration.
2. Use pliers to open the loop of the eight I-hooks so that
a rubber band can be inserted in the hook.
3. Hold the 4oz [120cc] fuel tank in position on the
main boom. Mark the location for the four I-hooks and drill a
1/16" [1.6mm] pilot hole at each mark.
4. Install the four I-hooks in the pilot holes.
5. Place a piece of foam rubber between the I-hooks.
Secure the fuel tank on top of the foam rubber with two #64
rubber bands. Connect fuel tubing from the fuel tank to the
carburetor and the pressure tap on the muffler.
6. Return to step 3 and install the second fuel tank.

Install the Canopy

1. Fit the top canopy on the canopy frame. Mark the outline
of the canopy on the wing. To help the glue adhere to the
wing, use a T-pin to poke small holes through the covering,
just inside the outline. If you prefer to remove a strip of
covering in the outline, do not use a hobby knife to cut the
film. A better method is to use a hot soldering iron as a knife
and melt the covering. This does not cut the balsa sheeting
which may weaken the wing.
2. Glue the top canopy to the wing and canopy frame with
epoxy. Wipe off any excess epoxy with a paper towel
dampened with denatured alcohol.
3. Glue two of the 1/2" x 1/2" x 1/2" [13mm x 13mm x
13mm] hardwood canopy mounting blocks to the servo
tray and the leading edge of the wing.
