Carl Goldberg GBGA0040 - Manual (Page 33)

1. ‡ Insert the soft rubber grommets into the mount-
ing holes of your servos.
2. ‡ Measure from the bottom of your servo to the
underside of a grommet. Add about 1/8” to this
measurement to get the total distance between
the wing platform and the servo rail.
‡ Referring to the plan, glue the rear rail against
Former “C”, at the predetermined height.
‡ Place a servo on the rear rail and determine
the location of the front rail. Be sure to allow
enough clearance to allow easy insertion and
removal of both servos.
‡ Glue the front servo rail in place.
3. ‡ Place both the rudder servo and the elevator
servo in position on the servo rails. The eleva-
tor servo goes on the right (as viewed from the
pilot’s seat) and the rudder servo goes on the
left. There should be approximately 1/4”
between them.
‡ Mark through the grommets for the location of
the servo mounting screws. Remove the ser-
vos.
‡ Using a 1/16” drill bit, drill holes through the
rails for the screws.
4. ‡ Referring to the plan, and using #2 x 3/8” sheet
metal screws, install the rudder servo on the
left and the elevator servo on the right.
‡ Untape the pushrod wires and attach each of
them to the corresponding servo, as shown.
2. ‡ Remove the servo wheel and install the CGM
pushrod connector, as shown. This device lets
you easily adjust the motor pushrod movement.
‡ Remount the servo wheel with the pushrod con-
nector in the approximate position shown on the
fuse top view on the plan.
3. ‡ From 1/16” scrap wire, cut a 2-1/8” length.
‡ Make a 1/4” bend at the end. Roughen the
unbent end with sandpaper.
‡ Slip the Snap-R-Keeper on the wire with the
clips toward the bend.
MOTOR SERVO INSTALLATION (3-CHANNEL)
1. ‡ Referring to the plan for proper location, insert
the motor servo onto the fuse side with servo
mounting tape.
ELEVATOR AND RUDDER SERVO INSTALLATION
4. ‡ Position a CGM snap nut about 1” onto the
straight end of the wire.
‡ Insert the wire through the pushrod connector
and add a second snap nut. (Trim the snap
nuts if they rub against the servo wheel.)
5. ‡ Attach the bent end of the wire to the motor
switch bracket and secure by sliding the Snap
R Keeper clips over the bend.
‡ Move the pushrod back and forth to simulate
servo action. Feel the OFF and ON switch lim-
its. Later, when setting controls, be sure to
adjust the snap nuts within the range of switch
movement.
