HINGING THE FLAP .
The control surfaces, including the
ailerons, elevators, and rudder, are
prehinged with hinges installed, but
the hinges are not glued in place. It
is imperative that you properly
adhere the hinges in place per the
steps that follow using a high-quality
thin C/A glue.
Note:
1) Carefully remove the flap from one of
thewingpanels.Notethepositionofthehinges.
2)Removeeach hinge from thewingpanel
andflapand place aT-pininthe center ofeach
hinge. Slide each hinge into the aileron until
the T-pin is snug against the aileron. This will
help ensure an equal amount of hinge is on
either side of the hinge line when the flap is
mounted to the wing panel.
3) Slide the flap on the wing panel until
there is only a slight gap. The hinge is now
centered on the wing panel and flap. Remove
the T-pins and snug the flap against the wing
panel. A gap of 1/64” or less should be
maintained between the wing panel and flap.

5) With the stopper assembly in place,
the weighted pick-up should rest away from
therear 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.

1) Using a modeling knife, carefully cut
off the rear portion of one of the 3 nylon tubes
leaving 1/2” protruding from the rear of the
stopper. This will be the fuel pick up tube.
