The wheel can now be mounted on the axle using the collets provided. Ensure that
the wheel is centred on the pivot line of the noseleg bracket.
Assembling and installing the fueltank
One of the tubes inside the fueltank must be angled towards the top of the tank, the
other to the bottom. If you heat the tubes gently with a heat-gun and bend them
carefully they will take up a smooth curve (see photo); take care not to kink the tubes,
as this would obstruct the fuel flow. Push a length of silicone fuel tube (about 90 mm
long) onto the fuel clunk pick-up.
Check that the clunk will be able to move freely inside the tank without binding or
jamming when the stopper is in place. It must not touch the back of the tank when
held vertically.
The tube for the overflow must extend right to the top of the tank, while the filler tube
must reach the bottom. Push short pieces of silicone tubing onto the tubes to achieve
this.
Now push the tank stopper over the neck of the fueltank and clamp it in place by
tightening the cross-head screw through the front spreader plate. It is important to
tighten the screw to the point where the tank is completely sealed.
Cut three pieces of silicone fuel tubing and push them onto the tubes where they exit
the fuel stopper. Mark the fuel lines as follows:
Clunk pick-up
Tube angled up
Tube angled down
Fit the fueltank into the fuselage through the wing saddle, threading the three silicone
fuel tubes through the hole in the nose bulkhead. The front of the tank should rest
against the rear of the firewall.
Install a strip of plywood across the fuselage sides behind the fueltank, resting
against the former, to ensure that it cannot shift backwards in flight. The strip can be
clamped or glued in place.
Installing the glowplug motor and silencer
These instructions only cover the method of installing the OS MAX FXI motor;
however, the procedure is exactly the same if you are fitting an OS MAX LA 46 or OS
MAX 46 AX motor.
Place the glow motor on the motor mount, and check that the mounting lugs rest
squarely on the mount arms. Now slide the motor back (towards the tail) to the point
where the distance between the firewall and the spinner backplate is 117 mm. With
the motor in this position, mark the location of the holes for the retaining screws on
the motor mount, using a size of drill which fits snugly through the holes in the
mounting flanges. Twist the drill in your fingers so that it makes a clear mark.
Drill 2.8 mm Ø holes in the motor mount arms to accept the motor retaining screws
(3.5 x 25 mm countersunk screws).
The next step is to screw the glow motor in place, but not before connecting the
throttle pushrod to the carburettor arm.
Cut away the cowl to clear the silencer, glowplug and needle valve. Attach the
silencer to the motor using the retaining screws supplied with it. The cowl should be
