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)Remove each hinge fromthewingpanel

andflap and placeaT-pinin thecenterofeach

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.

the aileron. You will see pre-drill hole 3mm for

the horn mounting screw on the aileron.

threads and prevent the crews from pulling

loose.

4) Thread a control horn end with aluminum

washer, lock nut until the top edge of the end is

18mm from the vase of the horn as shown.

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.

2) Usefour 4x30mm head boltsandfour4mm

washers to attach the engine mount rails to

thefirewall.Tightenthe screws . Make sure to

use threadlock on the screws to help prevent

them from vibrating loose.

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.
