control surfaces.
Connect the clevis on one of the long pushrods to the rudder horn (second hole from the outside), then slip
the pushrod into the guide tube. Screw the horn to the rudder, then file back the excess screw length flush
with the spreader plate.
The elevator horn must be bevelled slightly as shown in the photo, to obtain proper clearance. Attach it to the
elevator as described above.

Installing the undercarriage
You will find a channel on the underside of the fuselage to accept the undercarriage. Locate it using your
fingers (as described for the tailplane and fin slots) and melt away the film using a soldering iron. Fit the
undercarriage units in the channel, and position the saddle clamps over them. Drill pilot-holes for the
retaining screws and fit the screws to secure the undercarriage.
Fit the wheels on the undercarriage, and secure each with two collets. The outer collet should be fitted flush
with the end of the axle.
Installing the noseleg unit
The noseleg and steering arm are installed together: connect the pre-formed end of the steering pushrod to
the noseleg steering arm, then slip the pushrod into the guide tube. The inboard end fits through the cross-
hole in the pushrod connector on the rudder servo output arm. Install the noseleg unit as shown in the photo.
Tighten the clamping screw in the steering arm, taking care to engage the screw on the machined flat in the
wire.
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.
Installing the servos in the fuselage
Press the rubber grommets (supplied with the servos) into the servo mounting lugs. Push the brass tubular
rivets into the rubber grommets from the underside, so that the flange is at the bottom. You may find it easier
to insert the tubular rivets if you fit them on a small screwdriver first.
Place the servos in the servo plate in the fuselage, drill 1.5 mm Ø pilot-holes and secure them using the
screws supplied with the servos.
Cut down the cruciform servo output devices as shown in the photo. Drill out the linkage holes using a 2 mm
Ø bit: the outermost hole (lever length 13 mm) for the rudder and elevator, the inner hole for the steerable
nosewheel. Mount the pushrod connectors on the output arms; check that they rotate smoothly, but without
slop.
Pushrod connector mounting
Set the servos to centre from the transmitter, then fit the output arms on them, slipping the pushrods through
the cross-hole in the pushrod connectors at the same time. Hold the control surfaces at neutral as you
tighten the M3 grubscrews in the connectors, and lock each with a drop of thread-lock fluid.

Installing the switch in the fuselage
The switch should be mounted in the left-hand fuselage side in a position such as that shown in the picture.
Cut a rectangular hole in the fuselage side to suit the switch, install the unit and fit the retaining screws. If
you are using woodscrews, glue small pieces of plywood or spruce strip on the inside of the fuselage to
prevent the screws shaking loose.
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 blue silicone fuel
tube (about 90 mm long) onto the fuel clunk pick-up.
