9. Re-mount the elevator, rudder and throttle servos in
the fuselage.
Nylon
Control Horn
10. Hold the nylon control horns on the elevator and
rudder in the positions shown on the plan and mark the
mounting hole locations. Drill 3/32" holes at these locations.
horns (on both sides of the control surfaces) by poking
several holes with a pin, then applying thin CA glue.

nutplates which were attached to the horns.
2-56 x 5/8
Machine Screw
13. Screw a nylon clevis onto the threaded end of each
long steel wire pushrod. NOTE: Screw them on all the way
until the threads are protruding inside the clevis.
Nylon Clevis
14. Cut the short length of 1/8" diameter plastic tube into
several pieces, approximately 1/4" long. Slide at least six of
these pieces onto each of the long pushrod wires and space
them approximately 2-1/2" apart (do not glue yet). NOTE:
If these tubes do not slide on easily, cut them to a shorter
length.
SPACER
NOTE: While installing the pushrods, position the above
plastic tube spacers so they always stay inside the pushrod
guide tubes. If the tubes are not a tight friction fit on the
pushrod wires, apply a drop of thin CA to secure them.
15. Insert the pushrod wires into the pushrod guide
tubes (previously installed) and attach the clevises to the
elevator and rudder homs.
16. W h i 1 e
holding the rudder
and elevators in the
neutral position,
mark where the
pushrod wires cross
the holes in the servo
wheels where each
pushrod will be at-
tached.
17. R e m o v e
the elevator and
rudder pushrods and
make"Z-bends"at
the marks you just
made. Cut off the
excess pushrod wire.
18. U n s c r e w
the nylon clevises, re-
insert the pushrods,
and replace the
clevises. Remove the
servo wheels and
work the Z-bends
into the holes (drill
out the holes in the
servo wheels to
5/64" if necessary).
Finally, place the
servo wheels back
onto the servos and
check the operation
of the elevator and
rudder.
We recommend the following
CONTROL SURFACE THROWS:
NOTE: Throws are measured at the widest part of the
elevator and rudder.
ELEVATOR: (High Rate)... .5/8" up 5/8" down
(Low Rate) ... .3/8" up 3/8" down
RUDDER: (High Rate)... .1-1/2" right 1-1/2" left
(Low Rate) ... .7/8" right 7/8" left
AILERONS: (High Rate)... .5/16" up 5/16" down
(Low Rate) ... .3/16" up 3/16" down
NOTE: If your radio does not have "dual rates", then
set up the control surfaces to move at the high rate
throws.
