BUILDER TIPS
| 1. |
Epoxy Sensitivity - We have had reports back from three of our builders
that they have developed a sensitivity to the epoxy. Upon further checking,
it was
learned
that
none of them had religiously used the protective gloves and hand gel recommended
in the Quickie Education section. THIS IS A NO NO! Epoxy sensitivity is
a cumulative effect, and constant vigilence to keep the epoxy from contacting
the skin must be used. If all of the recommended safety precautions are
followed, a Quickie builder should have no problems with epoxy sensitivity
while building his Quickie.

Epoxy Developments - Our vendor on epoxy has developed a new epoxy that
initial testing indicates has a very low toxicity, and is compatible with
the Quickie method of construction. If further testing proves out, we expect
to switch to it within about six months. Applied Plastics, Inc. has had
a long history of major breakthroughs in epoxy systems; this new development
may go a long way toward eliminating epoxy sensitivity problems. |

Bending the Orange Foam - Some builders have reported considerable trouble in bending the orange foam for the fuel tank, seat-back bulkheads, etc. One of our builders triad soaking the foam first in a bathtub full of hot water, and found the tasc much easier. We see no problem with this providing that the builder allows the foam to completely dry before doing any glassing. Epoxy and water must not be mixed. When you think the foam is dry, leave it drying for another two days to be sure. A better method of bending the foam is to use a hand held heat gun.

| 4. |
Carb Heat Box - One of our Quickie builders, Richard Hoskins, thought that the routing of the hose from the aft end of the carb heat box to the right exhaust pipe would be better if the CH2 pipe in the carb heat box was angled about 45 degrees toward the right exhaust pipe. After examining his installation, we agree that it does provide more room around the throttle linkage area. (Reference page 17-9 of the Quickie Engine Installation plans).

Lee Heron suggests
making a lightweight antenna by stripping 23â of shielding from one end
of a coax cable; solder 3 wires 23â long to braid at base of stripped
wire; push antenna wire up into vertical fin foam core prior to Installation
of vertical fin on fuselage, and then run ground wires to rear along
leg and up each side of the fuselage.

Warping of Foam Cores - When hotwiring foam cores, always make sure that the top of the foam billet is evenly weighted down to prevent warpage of the foam billet. Once the core has been hotwired, it may be left in the billet until needed in order to minimize additional warpage. Do not store the foam in a location exposed to direct sunlight or very high temperatures.

Tailspring Support
- One of our builders discovered that the groove in the tailspring support
could be easily accomplished in 1.5 minutes by wrapping 60 grit sandpaper
around a 1/2" diameter tube (wood, metal, or tube) and sanding away.

Quickie Education Section
- Some builders are not doing the sample pieces detailed at the end of
the Quickie Education Section (bookend, stiffener, etc.) because they
think it will take them too much time! We estimate that doing the samples
will save the builder at least 25 manhours and result in a much better
aircraft. The samples give the builder the opportunity to experience
all necessary skills in a few hours on a non-aircraft series of parts.
Whenever someone reports having trouble glassing the fuselage, we ask
him if he did the samples; so far all reporting problems did not do the
samples. Please follow the plans in the sequence they are presented;
it will minimize difficulties.

Polyflo Tubing is not compatible with fuel and should be replaced for
fuel lines with either 1/4" I.D. vinyl tubing which is shipped with all
new kits, or black automotive fuel line tubing, available at most automotive

Page 17-4; In order
to permit greater throttle travel in the cockpit, the throttle cable
and carburetor push-pull tube pivot points on the governor assembly
may be switched with each other. This will require bending the carb push-pull
tube to avoid interference with the carb body.

under the head of the AN4-22A bolt must be a large diameter washer to
provide even pressure on the rubber mount as you tighten the bolt up.
A hardware store washer is OK.
