PLASTICS:
1.
For gluing plastic parts together, we suggest using plastic cement.
2.
Trim around the outside of the cowling on the flat base close to the edge of the cowling. You want to get close to the cowling but
not into it. Then, lay a sheet of 22- grit sandpaper on your work surface and rub the cowling flat on the sandpaper to sand up to the
bottom edge. This makes a nice smooth edge and keeps you from accidentally cutting too far. Cut a small hole in the front center of
the cowling, about ¼" Dia. for the shaft, nut, and washer to go through. Carefully trim inside opening for the air intake as this lets a
little air in to cool the motor, ESC, and battery.
3.
Trim out the exhaust stacks in the same way as the cowling. Glue the exhaust stacks to the cowling.
4.
Trim the radiator plastics the same way you did the cowling. Be careful here and take a little off at a time. Like the cowling, you do
not want to cut tight up to or on the side walls. Use sandpaper in the same way as the cowling to get nice flat surfaces. Glue the
halves of the radiator scoop together. Make sure you get a good bond. Trim the round recesses in the radiator out to fit the plastic
straw. Glue in the straw and trim it flush with the top and bottom surfaces of the radiator. After it has dried, mount the wing to the
fuselage. Glue the radiator to the bottom of the wing, using the holes in the radiator and screws holding the wing in place as a
guide.
5.
Trim and glue the seat parts together in the same way as the radiator scoop.
6.
Trim the cockpit as shown in the image below. You want the front and back of the cockpit sitting just between the formers on the
canopy frame (Do NOT glue it to the frame yet.)
7.
Trim the very ends off the canopy. Do not trim too far inward! Set the canopy frame in the fuselage and the canopy over the canopy
frame. Carefully mark the front and back of the canopy where it needs to be trimmed to fit the frame. (Just inside the opening in the
fuselage) You should hold off on trimming the sides until later. Trim the canopy a little at a time until the fron and back fit
properly.
8.
Glue the plastic seat from step 5 into the cockpit, using the slots as a guide.
9.
Paint the cockpit with as much detail as you would like.
10. Clean the inside of the canopy of any fingerprints or dust. Use an X-acto or light sandpaper to remove any paint from the cockpit
where it comes in contact with the canopy so you can get a good glue bond. Glue the cockpit into the canopy, making sure it is
centered and lined up front to rear. The cockpit will sit back from the front and rear edges of the canopy slightly to clear the canopy
frame formers.
11. Place some plastic wrap or wax paper in the cutout of the fuselage where the canopy section goes. This will keep you from
accidentally gluing the canopy frame to the fuselage. Set the canopy frame in place on the fuselage. Apply glue to the cockpit
frame formers and sides. Lay the plastic canopy down over it and hold it against the balsa until the glue sets.
12. After the glue has set, remove the canopy from the fuselage and trim the sides/bottom of the canopy to fit flush with the bottom of
the canopy frame.
13. Clean the plastic parts to remove any mold release or fingerprints and lightly sand with 600 grit sandpaper. Paint the plastics using
your chosen colors. Be light in the application of paint, as weight can add up quickly!
