4) Test fit the stopper assembly into the

tank.  It may be necessary to remove some of
the flashing around the tank opening using a
modeling knife.  If flashing is present, make
sure none falls into the tank.

Vent tube.

Fuel pick up tube.

Fuel fill tube.

5) With the stopper assembly in place,

the weighted pick-up should rest  away from
the rear of the tank and move freely inside the
tank.  The top of the vent tube should rest just
below the top of the tank.  It should not touch
the top of the tank.

6) When satisfied with the alignment of

the stopper assembly tighten the 3 x 20mm
machine screw until the rubber stopper ex-
pands and seals the tank opening.  Do not
overtighten the assembly as this could cause
the tank to split.

   Carefully use a lighter or heat gun to
permenently set the angle of the vent tube.

Important:

 

When the stopper assembly is in-

stalled in the tank, the top of the vent tube
should rest just below the top surface of the
tank.  It should not touch the top of the tank.

FUEL TANK INSTALLATION.

You should mark which tube is the vent

and which is the fuel pickup when you attach
fuel tubing to the tubes in the stopper. Once
the tank is installed inside the fuselage, it may
be difficult to determine which is which.

Rubber band.

Fuel tank.

M3 x 10mm.

C/A glue.

C/A glue.

GLOW ENGINE.
