4. Thread a nylon clevis 20 turns onto a 2-56 x 6" [152mm]
wire pushrod. Connect the clevis to the second hole from the
base of a nylon control horn. Using the elevator pushrod,
position the control horn in line with the servo arm. When
positioned properly the control horn will rest on a hardwood
plate in the elevator. Mark the location of the mounting holes
onto the elevator. Drill a 1/16" [1.6mm] hole on the marks,
drilling through the elevator plate only. Do not drill through
the top of the elevator. Install and then remove a #2 x 3/8"
[10mm] screw into each of the holes you have drilled. Apply
a drop of thin CA into the holes to harden the threads. Once
the glue has cured, secure the control horn to the elevator
with the screws.
❏
5. Slide a silicone clevis retainer over the clevis. With the
elevator servo and the elevator centered, mark the elevator
pushrod where it crosses the elevator servo arm. Make a
90° bend at the mark. Cut the pushrod 3/8" [9.5mm] past the
bend. Attach the pushrod to the elevator servo arm with a
nylon Faslink.
Install the Receiver
Before installing the rudder servo you need to complete the
installation of the receiver and battery. To properly set up the
rudder pull-pull system you will need to be able to operate
the servos.
❏
1. Use adhesive-backed hook and loop material to mount
the receiver to the bottom of the fuselage. The antenna can be
routed out the bottom of the fuse and taped to the covering.
❏
2. Connect the ESC, voltage regulator, elevator servo and
Y-harness for the ailerons to the receiver. (Depending on
where you mounted the ESC, you may need to install a 6"
[152mm] servo extension to the ESC.)
❏
3. Connect the fl ight battery to the ESC and check that
the servos are operating correctly. Arm the motor (with the
prop removed) and slowly start the motor to make sure it is
rotating in the correct direction.
❏
4. Over lap by 1" [25mm] two strips of nonadhesive-backed
hook and loop material. Route the hook and loop material
through the slot in the battery tray, under the tray and back
through the slot on the other side of the tray. Apply a strip of
adhesive backed hook material to the center of the battery
tray. The loop material can be applied to the battery.
