2. Install a 16" [406mm] servo extension to the elevator
servo. Secure the extension to the lead with tape, a piece
of heat-shrink tubing some other method to keep them from
coming unplugged.
❏
3. Install the elevator servo into the servo openings. Drill
through the servo mounting holes with a 1/16" [1.6mm] drill
bit. Remove the servo from the servo opening. Install and
then remove a servo mounting 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 hardened install the
servo into the servo opening using the 2 x 7 x 9mm servo
retaining plates. Center the servo and then install a servo
arm with a hole 3/4" [19mm] from the center.
❏
4. Thread a nylon clevis 16 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. Attach the control horn to the
elevator using two 2-56 x 3/4" [19mm] machine 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 Rudder Servo
Now is the time you need to decide on which rudder control
method you are going to use. Unless you are installing a
heavy motor, we recommend that you use the pull-pull system
to keep the weight out of the tail. To help you decide you can
install the wing, cowl and canopy. Mark the C.G. location on
the wing (shown on page 18). Then, place the plane on a C.G.
stand and position the fl ight battery in the middle of the battery
tray. If the plane is slightly tail heavy, we recommend that the
rudder pull-pull system be installed. If the plane is nose heavy,
the rudder servo can be installed in the tail.
Rudder Pull-Pull Installation
❏
1. Install the rudder servo centered in the rudder pull-
pull servo tray. Drill through the servo mounting holes with
a 1/16" [1.6mm] drill bit. Remove the servo from the servo
opening. Install and then remove a servo mounting 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
hardened install the servo into the servo opening using the
2 x 7 x 9mm servo retaining plates. Center the servo, and
then install a servo arm as shown.
