The ON / OFF switch can be installed in the right-hand fuselage side. Cut a hole in
the fuselage side to suit the switch you intend to use, and screw the switch in place.
Securing the flight batteries
The installation of the flight battery support requires a piece to be sawn out of one
former, as shown in the illustration.
Locate the battery support in the kit and place it in the fuselage. Position it so that it
engages at the front in the cut-out of the fueltank support, and can be fixed in place
at the rear with two panhead self-tapping screws.
Place the flight battery on the support plate and wrap cable ties right round them.
Check the model's Centre of Gravity, adjust it by re-positioning the flight pack, then
tighten the cable ties.
Installing the glow motor
The glow motor must be screwed to the arms of the motor mounts in such a position
that the distance between the rear face of the mounts and the front face of the
propeller driver is about 141 mm. Mark the hole positions on the arms of the motor
mounts, and drill the holes for the retaining screws. Fix the two motor mount units to
the nose bulkhead using the retaining screws provided. Apply a drop of UHU
schraubensicher to the screws to prevent them working loose.
The next step is to screw the motor to the mounts, but first the throttle pushrod must
be connected to the carburettor throttle arm. Slip the pushrod through the holes in the
formers in such a way that it exits through the opening for the throttle servo.
You may find it necessary to re-drill the holes for the throttle linkage in the nose
bulkhead, depending on the type of glow motor you are installing.
Fit the propeller and spinner on the motor shaft, and position the propeller blades at
around the '1 o-clock' position when the piston is at TDC (top dead centre); see also
the instructions supplied with the motor.
Mount the throttle servo in the servo plate, and fit the output arm on the servo's
output shaft. The servo should be at centre when the carburettor barrel is exactly
half-open. Mount the swivel pushrod connector on the servo output arm in such a
way that it rotates smoothly, but without significant slop.
Assembling and installing the fueltank
Cut a piece of silicone fuel tubing and push it onto the fueltank clunk weight. Push
the free end of the fuel tubing onto one of the tubes in the fueltank stopper, and
check that the clunk will be able to move freely inside the tank without binding or
jamming when the stopper is in place. Use a heat-gun or a match to heat the
projecting plastic tubes slightly; this will soften them, so that they can be curved to
the shape shown in the illustration. Check that one pipe points down (filler line) and
one up (vent line; this is the overflow when you are filling the tank). Extend these two
tubes with silicone fuel tubing so that they reach the top and bottom of the tank. Push
the stopper into the tank and tighten the cross-point clamping screw. Ensure that the
screw is tight enough to seal the fueltank completely. You can check this by holding
the tank under water: blow into the tubes and watch carefully: if bubbles rise, there is
a leak which must be sealed.
