! 2) Using a 3/32" drill bit, drill a hole
through the side of the fuselage, opposite the
muffler, even with the switch.
! 3) Make a push-pull lever out of scrap
wire. Attach the wire to the switch lever and
route the wire out the side of the fuselage,
through the hole you drilled.
Some switches come with a hole drilled
through the switch tab for this very pur-
pose. If your switch does not, remove the
switch and drill a 3/32" hole through the middle
of the switch tab.
! 4 ) Install the rubber grommets and brass
collets onto the elevator, rudder and throttle
servos. Test fit the servos into the preinstalled
servo tray. Because the size of servos dif-
fer, you may need to adjust the size of the
precut openings in the tray.
! 5) Position the servos into the servo tray
with the output shafts orientated as shown
below. Drill 1/16" pilot holes through the tray
for each of the mounting screws.

! 7) Connect the elevator, rudder and throt-
tle servos to your radio's receiver and turn on
the system. Set the trim tabs on the transmit-
ter to neutral and center the servo arms. The
elevator, rudder and throttle servo arms should
be perpendicular to the servos.
! 8) One at a time, hold the pushrods in po-
sition over the respective servos to check for
proper servo direction. If any servo turns in
the wrong direction, switch your radio's re-
versing switches as necessary to achieve the
correct direction.
