engine, all that is required is to remove part of the cowling from
around the spark plug and around the muffler tubes. Note: If you
are using an engine other than the FPE , you will have to adjust
the size and shape of the cowling openings to suit your engine.
TIPS ON CUTTING HOLES IN FIBERGLASS
First of all, be sure to wear safety glasses and a mask of some
kind to avoid inhaling any fiberglass dust. Use a fine point marker
to draw an exact outline of the area you want to cut out. Then use
a Dremel
®
Tool with a sanding drum to remove the material just
inside the lines you have drawn. Work slowly and carefully while
removing the material from the cowl. Check you progress often
and make sure you are not removing too much material. Finally,
use 220 sandpaper by hand to clean up any rough or jagged
edges. Make sure all edges are free of any loose glass fibers. Be
careful not to sand the paint on the outside of the cowl. Remove
all fiberglass dust from the cowl with a tack rag or with alcohol on
a clean cloth.
GAS ENGINE IGNITION MODULE:
❑
16) Our FPE engine operates on electronic ignition.
This
feature eliminates a great deal of bulk (weight) and makes for
easier starting and a smoother running engine.
The ignition
module is a small and separate unit that must be installed in the
nose of the fuselage, behind the firewall. It must be close enough
to the engine to allow the wiring to reach. The module wiring
consists of the spark plug lead, the ground wire, the electronic
module connection to the prop hub sensor, and the battery pack
lead. The battery pack lead stays in the fuselage and will be
connected to a separate battery pack & switch used to power the
system. The most convenient location for this module in our Sun
Dancer installation was at the lower left corner of the firewall.
a. Of course the module could be wedged in place with
foam but a cleaner and more sanitary installation was achieved by
making a mounting bracket out of 1/8" plywood, 1/4" triangle balsa,
and "J" bolts.
b. This bracket was then epoxied to the rear of the firewall
in the lower left corner.
Isolate the ignition module with foam
rubber and secured to the bracket with rubber bands. The leads
from the module are then routed through the hole in the firewall.
FUEL TANK ASSEMBLY:
❑
17) a. Two pieces 1/8" aluminum tubing has been provided in
the parts bag for venting the fuel tank. The first piece is 2" in length
and the second is 3-1/4". Insert the 2" piece of aluminum tubing
into the rubber stopper for the fuel pick up tube leaving 1/2" of the
tube protruding out the front of the stopper. Next, place a 90
O
bend
into the middle of the 3-1/4" aluminum tubing (making two equal
sides) to make up the overflow vent. Insert this into the rubber
