Install The Engine - THUNDER TIGER Dragonfly 15 Assembly Instructions Manual

INSTALL THE ENGINE

14.Locate the four pre-drilled wing dowel holes,
two on either side of the fuselage. Using a
sharp hobby knife, carefully cut the covering
away from each of the holes Insert one of the
wooden dowels into each of the wing dowel
holes. Ensure that an equal amount of dowel
extends from each side of the fuselage. You
might apply a thin coat of epoxy to the wing
dowels to prevent the dowels from becoming
fuel-soaked during flight.
FUEL TANK
15.Locate the fuel tank and the fuel tank acces-
sories. Assemble the fuel tank by first cutting
the silicone tube to 2"(53mm) in length. Press
the straight plastic nipple (the 90-degree nip-
ple is not used in this plane) into the rubber
stopper until the molded-in ring is against the
stopper. Rubbing alcohol applied to the nipple
will make it slip into the stopper easier. Now
slip the silicone tubing onto the nipple and
insert the metal clunk into the other end of the
tubing. Insert this assembly into the tank
(clunk first) and securely tighten the threaded
cap on to hold everything together. Note: It is
important to ensure that the fuel tank clunk
does not touch the rear of the fuel tank. If it
does, simply cut a small portion of the fuel tub-
ing until the clunk no longer reaches the rear
of the tank.
16.Cut two 5" (12cm) long of standard size sili-
cone fuel tubing (not furnished) and slip one
end onto the nipple extending out of the cap
and the other onto the top vent of the fuel tank.
Slide the fuel tank (cap end first) into the fuse-
lage from the wing saddle area, threading the
fuel lines through the oblong hole in the fire-
wall. The tank should fit tightly in the forward
formers.
ENGINE
17.Position the engine on the engine mount
beams so the distance from the prop hub to
the firewall is exactly 3 1/2"( 89mm). Using a
pencil or felt tipped pen, mark the engine
mounting plate where the four holes are to be
drilled. Note: Mark the mounting plate through
the engine mounting flanges. Remove the
engine and drill a 1/8"(3mm) hole through the
beam at each of the four marks.
