Glue the plate for the V-tail servos in the
fuselage under the opening in the wing sad-
dle. Thoroughly roughen the inside of the fu-
selage beforehand to ensure that the glue
adheres well.
Check that the servos fit in the apertures
before gluing the plate in the fuselage!
Screw the servos to the servo plate using the
retaining screws and rubber grommets sup-
plied in the servo accessory pack.
Connect the steel pushrods to the servo
output arms using the threaded couplers and
clevises supplied.
V-tail
The two steel joiner rods for the V-tail have to
be glued in the fuselage: start by fixing the
fuselage on the workbench with the wing
saddle horizontal. Ensure that it cannot shift,
and that you can see clearly into the tail end.
Fit the rods and the balsa support rail in the
fuselage as shown. Use a metal file to
roughen the joint areas inside the fuselage to
ensure that the glue adheres well.
Now fit the V-tail panels on the joiner rods
and align them accurately.
The included angle of the tail panels is 110
degrees. If the tail panels cannot be pushed
fully against the fuselage, the joiner rods
need to be shortened slightly.
When you are confident that the tail panels
are correctly positioned, glue the steel rods in
the fuselage using 5-minute epoxy, taking
care to produce really sound joints. Fix the
tail panels so that they cannot shift. Allow the
epoxy to cure completely (preferably over-
night) before you remove the tail panels
again.
The pushrods in the fuselage are connected
to the V-tail panels by means of pre-formed
steel rod horns with linkage balls attached;
glue these in the tail control surfaces as
shown. The ball-links allow the linkages to be
disconnected easily, and they can also be ad-
justed by screwing in or out on the threaded
couplers.
Installing the motor
The first step is to glue the GRP motor bulk-
head in the fuselage. Press it firmly against
the fuselage while you tack it in place with
thin cyano; it can then be glued permanently
using 5-minute epoxy. Keep the bulkhead
exactly parallel to the front edge of the fuse-
lage: the motor shaft must be angled slightly
down (about 2°) and very slightly to the right
(as seen from the tail; about 1°).
