7. Slide the tail wheel wire through the hole in the bracket.
Insert a 4-40 set screw into a 3/32" [2.4mm] wheel collar. Then
slide the wheel collar onto the tail wheel wire. Slide the tail
wheel wire into the nylon bearing. Center the bracket to the
fuselage. Mark the location of the bracket mounting holes onto
the fuselage and then remove the tail wheel wire. On the marks
you made, drill a 3/32" [2.4mm] hole through the plywood.

8. Bend the wire as needed to get a good alignment with
the pin and then slide the end of the wire from the tail wheel
assembly into the hole in the nylon pin. Secure the tail wheel
assembly to the fuselage with two #4 x 1/2" [12.7mm] screws.

9. Slide the tail wheel onto the tail wheel wire and secure it
in place with a 3/32" [2.4mm] wheel collar and 4-40 set screw.
Install the Elevator and Rudder Servos
The following instructions will cover installation of the rudder
and elevator servos. For the elevator servos to work properly
your radio system must have the ability to adjust the servo
direction independently from each other. If your radio does
not have this capability you will need to purchase an after
market "in-line" servo reverser. For Futaba this is the SR-10
dual servo reverser (FUTM4150). A standard "Y"-connector
will not work properly.

1. Install a 24" [610mm] servo extension onto the servo
lead. Secure the extension to the lead with tape, a piece of
shrink tube or some other method to keep them from coming
unplugged.

2. Cut 1" [25.4mm] from the non-threaded end of two
of the 4-40 x 6" [152mm] wire pushrods. Solder a 4-40 solder
clevis to the non-threaded end of the wires. Once the solder
has cooled install a silicone clevis keeper over the clevis.
Thread a nylon swivel ball link onto the threaded portion of
the wire. Enlarge the outer hole in a 1" [25.4mm] servo arm to
1/8" [3.2mm] to accommodate the bolt for the swivel connector.
Install the swivel ball link into the outer hole. Be sure to apply
a drop of thread locker to the threads of the bolt.

3. Center the servo. Then, install the servo arm to
