foam core, and run the lead through the central 12 mm Ø hole. Set the servo to centre
from the transmitter. Cut down the servo output arm as shown in the picture and fit it on
the servo. Sand the servo case to provide a "key" for the glue, then epoxy the servo in the
recess in the tailplane.
Assemble the parts of the elevator horn as shown, remove the covering film round the
horn hole in a circle the same size as the horn base, and glue the horn in the elevator.
When the glue has set hard, make up the elevator pushrod and adjust it so that the
elevator is exactly at centre when the elevator servo is in the neutral position.
The servo well can be covered with a piece of scrap film from the wing. Melt the film over
the two screw-holes using a hot soldering iron. Drill and file out a 13 mm Ø hole in the
tailplane mount on the top of the fin to accept the elevator servo lead.
The fuselage (electric version)
The first stage here is to remove the fuselage nose. Assemble the parts of the laser-cut
template, and place it over the nose in accordance with the letters. Mark the cut-line on
the fuselage using a pencil. Cut off the fuselage nose, leaving the pencil line visible.
Use the spinner backplate to check the diameter of the fuselage nose, and adjust the cut
face if necessary.
When adjusting the cut-line, remember to take into account the downthrust and side-thrust
required for the motor. Screw the motor to the motor bulkhead, and place this assembly in
the fuselage through the canopy opening. Fit the spinner backplate on the motor shaft,
check alignment, and tack the bulkhead to the fuselage using a little cyano when you are
satisfied with the fit.
Now remove the spinner again, unscrew the motor, and apply a generous fillet of EPOXY
RESIN round the bulkhead to produce a really sound joint.
If you intend allowing the motor to run for long periods, we recommend that you cut
cooling slots in the fuselage on both sides of the motor; they should be about 5 mm wide
and 25 mm long.
Allow the epoxy to cure completely, then glue the two half-formers in the fuselage, using
the rudder servo / battery support plate to position them correctly.
When the epoxy has set hard, glue the support plate to the two half-formers and the
fuselage.
The rudder servo is mounted in a Servo-Lock, but first the mount should be cut back at the
top to the point where the top edge is flush with the rubber grommets.
The Servo-Lock can now be glued in the support plate.
Drill a pilot-hole in the half-former in front of the Servo-Lock, and screw a ring-screw into it.
This is for the rubber band or coil spring which retains the canopy.
Allow the glue to set hard, then install the servo in the Servo-Lock using the retaining
screws, rubber grommets and metal spacers supplied with it.
