the covering. Note: A partial servo horn arm should be
used to relieve tension on the antenna right before it exits
the fuselage behind the pilot. Use a medium T-pin to attach
a small rubber band to the top portion of the vertical
stabilizer. Tie the antenna to the rubber band using tension
to keep the antenna tight. Use caution not to damage the
antenna. A servo horn can be cut and used to hold the
antenna in place with less likelihood of damage to the wire.
Final Assembly
3. The plug assembly can now be inserted into the tank.
The pressure tube should be adjusted so the tube is
pointed straight up just under the top of the tank. Caution:
The pressure tube should not touch the top of the tank or
fuel shut off and engine failure may occur. The stopper
discs on the rubber plug must be tightened by turning the
self tapping screw. Do not over-tighten the plastic stopper
plates or damage to the tank may occur.
Bending the Pressure Line
1. Being careful not to kink the tube, bend one end of
the tube in a 90° angle. It may be helpful to find a rigid
object that can be used as a form to bend the tube around.
Leave 1-1/2" of straight tube at one end so it can easily be
inserted through the tank plug.
Assemble the Tank Plug
2. Locate the two plastic plug discs. Push the aluminum
tubes through the smaller stopper disc and the back of the
rubber plug. Place the larger stopper disc on the opposite
side and insert the 3 x 18mm self tapping screw through
the larger disc, rubber plug and then into the smaller disc.
Locate the metal fuel pick-up weight (clunk) and the
medium silicone fuel tubing. Insert the fuel pick-up weight
into the fuel tubing. Compare the length of the fuel tank to
the length of the fuel tubing and cut the tubing so that the
fuel pick-up weight on the end of the tubing will not touch
the end of the tank. Do not tighten the screw at this time.
Insert Tank into the Fuselage
4. Insert the fuel tank into the fuselage. Use medium CA
to glue the tank bracket into the fuselage behind the tank.
The bracket will fit into the lightening hole in both sides of
the fuselage.
