Locate the aileron and ap control horns.
e taller control horn is used for the ailer-
ons, and the shorter horn for the aps.
Use sandpaper to scu the bottom of the
aileron and ap control horns. Use a paper
towel and isopropyl alcohol to remove any
oils or debris from the control horns.
Check the t of the control horns to the

Remove the control horns from the
control surfaces. Apply epoxy to the slot
in the aileron and ap. Make sure the
epoxy gets into the slot for a good bond

Before the epoxy fully cures, remove
the tape from around the control horn.
is will allow the epoxy to ow around
the control horn, creating a small let
between the control horn and surface for

INSTALLING THE STOPPER
ASSEMBLY
Using a modeling knife, carefully cut
o the rear portion of one of the 3 nylon
tubes leaving 1/2” protruding from the
rear of the stopper. is will be the fuel
pick up tube.
Using a modeling knife, cut one length
of silicon fuel line. Connect one end of
the line to the weighted fuel pick up and
the other end to the nylon pick up tube.

Carefully bend the second nylon tube up at
a 45º angle. is tube is the vent tube.

Test t the stopper assembly into the tank.
It may be necessary to remove some of the
ashing around the tank opening using a
modeling knife. If ashing is present, make
sure none falls into the tank.
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. e top of the vent tube should rest just
below the top of the tank. It should not touch
the top of the tank.

Focke- Wulf FW190 Instruction Manual.

When satised with the alignment of the
stopper assembly tighten the 3 x 20mm ma-
chine screw until the rubber stopper expands
and seals the tank opening. Do not overtight-
en the assembly as this could cause the tank
to split.
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 dicult to determine which is which.
