Locate the plywood plate for the V-tail ser-

vos, and glue it in the fuselage under the

wing saddle. Roughen the inside of the fuse-

lage thoroughly to provide a mechanical 'key'

for the epoxy. Before installing the servo

plate install the servos temporarily, and mark

the correct height of the plate on the fuse-

lage sides.

•

Screw the servos to the servo plate using the

retaining screws and rubber grommets sup-

plied in the servo accessory pack.

•

Solder threaded couplers to one end of the steel pushrods, then screw a clevis on each coupler.

Slip the pushrods into the snake outers from the servo end, and connect the clevises to the servo

output arms.

V-tail

•

Slide the V-tail panels onto the wire dowels

already bonded into the fuselage.

•

The control surface horns take the form of

pre-formed steel rods with a linkage ball on

one end. Drill a 1.6 mm Ø hole in the root

face of each control surface to accept the

horns, taking care to keep the drill exactly

parallel with both sides of the panel.

•

Thoroughly roughen the pre-formed steel

horns before gluing them in the V-tail control

surfaces. Check that both horns are at the

correct angle: the linkage balls must line up

exactly with the hinge pivot axis. Ensure that

the linkage balls do not foul each other when

the tail panels are in place on the fuselage.

•

Now solder a threaded coupler to the tail end

of each steel pushrod before screwing the

ball-links onto the couplers. The ball-links

can easily be fitted and removed, making it

easy to remove the V-tail panels.

Installing the electric motor

•

The first step here is to glue the GRP motor

bulkhead in the fuselage: screw the motor to

the bulkhead, and push this assembly firmly

into the fuselage nose from the inside. Set

the bulkhead exactly parallel to the front face

of the fuselage. Temporarily fit the propeller

on the shaft, and check that the spinner

backplate is parallel with the fuselage nose.

•

Tack the bulkhead to the fuselage using thin

cyano, then remove the motor and reinforce

the joints with 5-minute epoxy.
