Top Flite LustreKote high quality paint perfectly matches Top
Flite MonoKote film. The paint is well suited to putting a high
quality finish on ABS (canopy and radiator housing), but
does have a tendency to curl materials such as styrene and
butyrate.
If you have any doubt about the material you are painting, we
suggest painting on a small piece of leftover material. Monitor
it for a few days to be sure it is compatible with the paint.
We used LustreKote White (TOPR7204), Black (TOPR7509),
Aluminum (TOPR7205), Cub Yellow (TOPR7220) and Insignia
Blue (TOPR7207)
❏
1. Trim the ABS radiators along the bottom. Sand the
3-ply radiator housing mounts flush with the bottom of the
radiators. The end of the housing mounts may need to be
sanded at a slight angle and the corners rounded.
❏
2. Use CA to glue the housing mounts to the housings.
Sand the housing mounts and the radiators flush.
❏
3. Two of the radiator housings are glued to the outside
of the main booms, one on each boom, over the rudder and
elevator servos. Position the radiator housings centered
over the servos and mark the outline of the housing.
Remove the radiator housing and trim the covering from
inside the outline. Use epoxy to attach the housings to the
main booms. Use a paper towel dampened with denatured
alcohol to wipe off any excess epoxy before it hardens.
❏
4. For the two radiator housings that are on the inside of
the main booms, trim an opening on one end to allow the
rudder and elevator pushrods to exit.

Suggested Covering Sequence
Cut two black stripes 2-3/8" wide by 11" long [60mm x
279mm]. Lightly wet the glass between the white stripes
and position the black stripes overlapping the white
stripes by 1/4" [6mm]. Use a squeegee and paper towel
to remove the glass cleaner from under the black stripes.
With your covering iron set close to high, iron down the
seams between the stripes. Allow the covering to cool for
a minute and carefully start lifting one end of the white
covering. The black and white strips and the aluminum
film should be connected along the seams. If they are not,
increase the heat of the covering iron and move it slower
over the seams, repeating the process. It may require
more heat than normal for the film to seal, because the
glass absorbs some of the heat.
After removing the film from the glass, position the film on
the wing with the white stripe against the boom. Use your
covering iron to tack the film down every few inches.
Then, go back and seal the covering to the wood all over.
A heat gun can be used to carefully shrink the covering,
but care must be taken to not pull the seams apart. Avoid
heating the overlapping seams at the same time as
heating the rest of the covering; otherwise, the seam may
pull apart.
