Step 4
Remove the control wire and make a 90-degree "L" bend as
shown. Cut off the excess wire 5/16" from the bend. Remove the
clevis and slide the control wire through the tube from inside the
fuselage and connect the wire to the servo arm using an L-bend
keeper. Thread the clevis back on to the wire and reconnect the
clevis to the control horn on the elevator.
Note: To prevent the control wire from binding, trim off
the servo arm pointing to the rear.
Step 5
Locate the throttle control wire (20") and slide it through the
pre-installed throttle tube in the firewall. Connect the clevis to the
throttle of your engine. With the servo centered (half throttle) and
the carburetor half open mark the throttle wire where it crosses
the outer hole of the servo arm.

Remove the throttle control wire and make a 90-degree L-bend as
shown. Cut off the excess wire 5/16" from the bend. Remove the
clevis and slide the control wire through the tube from inside the
fuselage and connect the wire to the servo arm using an L-bend
keeper. Thread the clevis back on to the wire and reconnect the
clevis to the throttle.
Step 7
Remove the servo arm from the rudder servo. Trim off the two
shorter arms and install the easy connector included in the Alpha
hardware package as shown. Re-install the servo arm with the
easy connector positioned to the left side of the fuselage.
