Take care to keep tools, adhesives and paints out of the reach of children.
When using solvent-based adhesives it is important to work in a well ventilated place.
Take waste glue and paint back to the model shop for disposal, or to your local toxic waste collection
centre.
A large, unobstructed working area is a great advantage for all types of model-making.
If you are a relative beginner and are not sure of any process, please ask an experienced modeller for
advice.
The wing
Installing the servos in the outboard wing panels.
The first step is to install the servos in the outboard wing panels. Repeat each procedure with the
second wing panel. The servos are screwed to the wooden frames supplied in the kit, which are then
glued in the wings. Use abrasive paper to roughen the joint area thoroughly inside the outboard wing
panels, to provide a “key” for the epoxy.
Locate the pushrod position just forward of the aileron, and cut the pushrod clearance slot using a 4
mm Ø twist-drill and file.
Fix the servo to the wooden frame using the screws supplied with the servo.
Cut down the servo output arm as shown in the photo.
Set the servo to centre from the transmitter, then fix the prepared output arm on it, exactly at right-
angles to the servo case.
The servo lead must now be extended before the servo can be glued in the wing. Connect an
extension lead, Order No. 3935.18, to the servo, and secure the connection permanently using a drop
of cyano or a heat-shrink sleeve.
Apply glue to the servo frame and fit the servo assembly in the wing as shown.
Ensure that the servo output arm is exactly in line with the hole for the aileron horn.
Press the servo lightly against the top wing skin until the epoxy has set.
When the glue has cured, run the extension lead through the rectangular opening in the root rib of the
output wing panel.
The next step is to prepare the brass aileron horn as shown in the picture. The horn must be cut down
to an overall length of 13.5 mm.
Flap horn
Aileron horn 13.5 mm
Screw the horn into the aileron as far as it will go. Take care to screw in both aileron horns to the
same depth; you can check this by measuring the distance from the trailing edge to the linkage hole.
Connect the clevis to check freedom of movement.
The next step is to make up the pushrod from the servo to the aileron. Each pushrod consists of two
M2.5 clevises and a length of M2.5 studding (cut from the full-length threaded rod supplied).
The clevises can be secured on the pushrod using thread-lock fluid or a drop of cyano.
Screw the pushrod into one clevis, and connect the clevis to the aileron horn. Connect the second
clevis to the servo output arm and mark the correct length of the pushrod. Cut the pushrod to length,
screw the clevis onto the cut end and secure it.
