GET THE SKILLS
TO GET IT BUILT
“Riveting was pretty intimidating and I wasn’t sure I could build an aluminum airplane. The EAA
SportAir Workshop took all the mystery out of it and did a great job showing just
how easy it was. When I got home I ordered the quick-build kit and four years later I was
flying. Thanks to EAA SportAir Workshops for helping this builder complete his life-long dream.”

building basics
no insulation in place, see how hot
the top of the engine gets. Try the
same thing with an old comforter or
moving blanket in place, and you will
be able to see the difference.
Finally, be careful with the use of
heat lamps such as 100- and 250-
watt “brooder” lamps. While they
are an effective source of heat, great
care must be taken in where they are
pointed. These lamps are designed
to produce heat in the visible and
infrared ranges, and as a result, they
can generate sufficient heat to damage
and scorch paint, may remove the
temper from some metal materials
with sufficient exposure, and may
warp or melt some composites.
Again, a good insulating
blanket will help to
keep the heat where you
want it.
Fan-driven space heaters can also
be used to heat up aircraft engines.
These units range from 500 to
1,500 watts or more. By using your
skills, you can connect a flange and
exhaust duct, and then port the hot
air into your engine compartment,
where it will warm up the engine
compartment. Again, a good
insulating blanket will help to keep
the heat where you want it.
Always On or Timer-Controlled?
Looking at this issue from the sense
of saving money, cycling the heating
source on and off seems to make
sense. However, looking at how this
will affect the engine points in the
opposite direction.
Consider this: As you heat the
engine, the air in the engine is
heated and expands. Since the
engine has a breather, some of
this heated air is pushed out of the
engine. Later, when the heating
source is turned off, the colder and
moist air will be drawn into the
