13) Position the winglet into place on the wing and
drill four 1/16” holes at the pin punches, through
the winglet plate into the plywood in the wing.
Watch to be sure you do not
pinch wires as you assemble
the winglet to the wing.
14) Secure the winglet in place
with four 2.3 x 12mm washer
head screws (#36)
15) Test the operation of the rudder again to be sure there is no interference
from the mounting plates in the wing.
Mounting Aileron Servos
For installing the aileron servos you can either unplug and remove the winglet from the wing, or
work on the wing with the winglet overhanging the edge of the workbench.
1) Locate the aileron servo bay cover on the bottom of the right wing and remove it
Note that the slots for the aileron servos are ‘outboard’ from the plane’s center line, and
are left and right (opposite) to each other. This is because the ailerons operate in
opposite directions.
Note also that the factory used clear tape that is pain to remove. Using the point of a
razor knife you can carefully lift an edge. If you dent the balsa surface, re-heating the
covering will make the dent disappear. If there is an adhesive residue it is easily removed
with ‘Goo Gone’ or VMP Naptha
2) Trim the slot opening of each servo cover with a sharp razor knife.
(Don’t use the soldering iron
trick, as it will show the melted
edge where it would be visible
from the bottom side of the
plane. When cutting with the
razor knife cut on the ‘push’
stroke – this will give a cleaner
edge.)
3) With the covers in place, drill a
1/16” (1.5mm) hole at each
corner. Make sure the cover is oriented properly and
that the slots are towards the wing tip. Test fit the covers in place with four 2.3mm x 6mm
washer head screws (#2), then remove and place a few drops of Thin CA into the holes in
the wing to dry and strengthen the threads.
The standard size servos are mounted directly to the bottom
of the servo bay covers. Mounting blocks are provided, or
your may use two sided adhesive foam tape.(Not supplied).
Verify that the servo arms are electrically neutral and you
are using the length of arm you intend to use. (Refer to your
Radio owners’ manual for techniques for centering the servo
arm.)
