Aileron Extension Installation
1.
Gather the following items.
(2) 12” extension wires
NOTE: Before starting, remove the servo door and
make sure the length of one servo wire, when
plugged into the 12” extension, is long enough
to reach to the center of the wing. If necessary, add
an additional extension to reach the center of the
wing.
IMPORTANT! To ensure that any connections
located inside the wing will not come loose, either
when the wires are pulled, or during flying, always
tape them securely together with electrical tape.
2.
Remove servo door and, making sure to use
the correct servo for the opening, attach the
servo wire to the12” extension and securely
tape connection.
NOTE: Before continuing, make sure the other end
of the string inside the wing, next to the second
aileron hole, is taped firmly to the wing, so that it is
not pulled out by mistake. (If it becomes necessary
to reinsert this string into the wing, tie a 6-32 nut to
the end of the string and feed it back into the wing.
The nut will easily fall through the wing rib holes.
Tie the other end of the extension to the
string that exits the servo opening and tape
this connection, also.
3.
Grasping the string in the hole in the center
of the wing, SLOWLY pull until the end of the
12” extension comes out of the hole. Work
the string back and forth to get the extension
plug to go through the cutouts in each rib.
Pull gently and have patience.
4.
Tape the extension securely to the wing, so
that it will not slide back in while you are
working.
Repeat these steps for the other half of the
wing, so that both servo extensions are exit-
ing the holes in the center of the wing..
Control Horn Installation
1.
Collect the following items:
(2) Large control horn with back plate
(4) 2-56 x 3/4” screw
(2) 1/16 x 7” threaded wire
(2) Snap-link
(2) Nylon snap nut (molded 6-up - see photo in
Engine Pushrod Installation)
2.
Replace the servo door and screw it down
onto the wing.
3.
Make a mark at a 90º angle to the trailing
edge and in line with the servo arm.
