d) Now untape the string at the root end of the wing panel
and begin carefully pulling the string and the aileron cord
through the wing. You will occasionally feel like the wire
has become stuck inside the wing. This is simply the
plug on the end of the servo wire hitting the side of one
of the holes in the wing ribs. Gently work the string back
and forth from both ends until the plug slips through the
hole. Sometimes the servo plug comes through all the
ribs the first time without getting hung up, and other
times it seem like it gets hung up on every rib. Be patient
and don’t try to force it.
e) Mount the aileron servo and hatch to the wing. Using a
1/16 dia. drill bit, drill pilot holes in the plywood mounting
tabs in the wing panel. Use the four holes in the servo
hatch as your drilling guide. Four M2.3 x 7mm screws
are provided to mount the hatch to the wing.
f) Repeat steps c), d), and e) to install the other aileron
servo and hatch.
❑
3) Both flap servos need a 6" extension cord in order to exit
at the center of the wing. A reversing Y-harness stays plugged
into the receiver for the flaps. When the wing is put on the
airplane, the flap extension cords are plugged into the
Y-harness. Prepare the servos for mounting by installing the
rubber grommets and eyelets (supplied with your radio system)
in each servo.
a) Attach the extension cords to the flap servos and secure
the plugs together with tape or string.
b) Remove the flap servo hatches from the bottom of the
wing. Drill pilot holes for the servo mounting screws.
Then mount the flap servos on their hatches using the
screws that came with your servos.
c) Insert the flap servo wire and the hatch into the flap
servo bay and fish the wire out to the center section (you
shouldn't need a string to do this over the short
distance). Make sure both the flap and aileron servo
wires exit the wing panel through the round servo wire
hole in the bottom surface of the wing. It’s a good idea
to label the servo leads to easily identify the flap from the
aileron.
d) Mount the flap servo and hatch to the wing, using four
M2.3 x 7mm screws that are provided.
e) Repeat steps c) and d) to install the other flap servo and
hatch.
INSTALLING THE AILERON CONTROL HORNS & PUSHRODS
For the following steps you will need:
(2) Nylon Control Horns w/ Clamp
(6) M2 x 30mm Bolts for control horns
(6) M2 Hex Nuts for control horns
(2) 4" long Pushrods for ailerons
(4) Metal Clevis w/ M2.7 thread
(4) Short pieces of Fuel Tubing
❑
4) At this point connect up your radio system so that you
can operate the aileron servos in order to make final
adjustments to their neutral position and overall travel.
a) Turn on the radio system and center the aileron trim
lever on the transmitter. Check to see if the aileron servo
arms are both perfectly centered on each servo. Adjust
the arms if necessary.
b) Determine if the servos are moving the correct direction.
Correct if needed.
c) Make sure the servo arm does not travel too far and hit
the ends of the slot in the hatch. Use the end point
adjustment feature of your transmitter to correct this in
needed.
❑
5) Install the aileron control horns.
a) First locate the predrilled holes in the aileron. Check to
make sure the covering on both sides of the aileron is
open over the holes. If needed run a drill bit through the
hole to open up both sides.
b) Slide three M2 x 30mm
bolts
through
the
control horn and then
through the bottom of
the aileron. Push or
screw them in until they
first begin to come
through on the other
side.
c) Place the nylon clamp
piece on the other side
of the aileron and feed
the bolts through the
holes in the clamp.
