The rudder servo and the two elevator servos can now be installed permanently in the
fuselage. Connect the two rudder cables to the servo output lever as shown in the photo.
Set the rudder to centre, and the rudder servo to neutral (centre) from the transmitter.
Mark the length of the two elevator pushrods, and bend them at right-angles at the
marked point using a pair of flat-nose pliers. Cut off the excess rod length, leaving about
1.5 mm projecting beyond the retaining clip.
Cut an opening in the right-hand fuselage side for the ON / OFF switch, and install the
switch using the screws supplied with it.
Locate the hole in the throttle servo output arm which is 11 mm from the centre, and drill
it out to 2 mm Ø. Mount the swivel pushrod connector in the hole, tightening the nut just
to the point where the barrel rotates smoothly, but without noticeable slop.
Installing the glowplug motor
Position the glow motor on the two motor mount arms in such a way that the distance
between the rear face of the motor mounts and the front face of the propeller driver is
about 126 mm.
Attach the motor mount assembly to the nose bulkhead in such a way that the centreline
of the motor is about 6 mm above the marked point on the nose bulkhead when viewed
from the side.
Fix the motor mount to the bulkhead using the screws and captive nuts supplied. Secure
the screws with thread-lock fluid to prevent them shaking loose. The upper motor mount
arm has to be shortened as shown in the photos.
The glow motor must be removed from the motor mount again in order to connect the
throttle pushrod. Connect the pre-formed end of the throttle pushrod to the carburettor
throttle arm, then slip the pushrod into the guide tube whilst fixing the motor on the
mount again. Thread the pushrod through the cross-hole in the swivel pushrod
connector fitted to the throttle servo.
Attach the silencer to the motor using the specified spacer if necessary. If you think the
silencer hangs too low, you can cut a piece about 10 mm long from the spacer, and file
the cut face flat.
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 the straight tube 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. Rotate the unused plastic tubes so that one faces down (later the
filler line) and the other faces 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 respectively. This ensures on the one hand that the tank can be filled
completely, and on the other that it can be drained completely after the flight. 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.
