There are three molded holes in the rubber fuel
tank stopper. Two are opened and one is cov-

ered by a thin layer of rubber on the front of the stop-
per. Using a modeling knife, remove the thin layer of
rubber to completely open the third hole.

3) Push the single 4mm x 28mm nylon pickup

tube through one hole in the rubber stopper until 3/8”
protrudes from the front of the stopper. Slide the ny-
lon backplate over the tube at the back of the stopper.

4) Push one 4mm x 28mm prebent nylon vent

tube through the nylon backplate and through the rub-
ber stopper until it protrudes 3/8” from the front of
the stopper.

5) Using a modeling knife, remove part of the

second nylon vent tube as shown below. This will be
the fill tube. Push it through the nylon backplate and
through the rubber stopper until it protrudes 3/8” from
the front of the stopper. It is used in conjunction with
the fuel filler that will be installed later. Orientate the
tubes as shown. See figure # 12 below.

6) Slide the nylon fuel cap over the three tubes

at the front of the stopper. Insert the 3mm x 18mm
self tapping screw into the center hole in the cap. Push
the screw through the stopper and into the nylon back-
plate. Begin to tighten the screw, but do not com-
pletely tighten it at this time.

7) Slide the silicon fuel tubing, with the

weighted pickup attached, onto the rear portion of the
nylon pick-up tube. See photo # 21 below.

STOPPER INSTALLATION

8) Press fit the stopper assembly into the tank

opening. The stopper should be rotated so the nylon
vent tube is pointing straight up towards the top of
the tank. See photo # 22 below.

9) With the stopper assembly in place, the

weighted pick-up should be about 3/8” from the rear
of the tank and move freely within the tank. Adjust
the length of the tube accordingly.

10) When satisfied with the alignment of the

stopper assembly, tighten the 3mm x 18mm self tap-
ping screw until the stopper expands and seals the
tank opening. Do not overtighten the screw as this
could cause the tank to split.

For added security you may wish to apply a thin
bead of silicon sealer around the fuel cap where

it seals around the front of the tank. Make sure not to
get any sealer in the nylon fuel tubes.

FUEL TANK INSTALLATION

11) Install three lengths of silicon fuel tubing

onto the vent, fuel pick-up and fuel filler tubes at the
front of the tank. Slide the fuel tank into position in
the tank compartment while feeding the fuel lines out
the predrilled hole in the firewall. The tank should
be installed so that the top of the tank faces the top of
the fuselage and the stopper assembly should engage
the predrilled hole in the firewall.

Do not permanently secure the tank in place until
after balancing the airplane. It may be neces-

sary to mount the receiver or the battery pack inside
the tank compartment to help balance the airplane.
After you have completed balancing, secure the tank
in position using a couple of dabs of silicon sealer
between the tank and the forward bulkhead. We also
recommend sealing the predrilled hole in the firewall
with silicon sealer to prevent exhaust residue from
entering the fuselage.
