Parts Needed

Fuselage assembly
Rudder 
Hinges
Tail wheel assembly

Tools and Adhesives Needed

Thin CA
CA remover/debonder
6-minute epoxy
Sharp hobby knife
Drill 
Drill Bit: 3/32", 1/16"
Pliers
Rubbing alcohol
Paper towels

Step 1.

Locate the tail wheel assembly and use pliers to make a

90-degree bend 1" up from the bushing as shown. Measure over
1" from the bend and trim off the excess wire. This portion of the
wire will be inserted into the rudder.

Step 2.

Temporarily install the rudder using the hinges 

provided; do not glue the hinges at this time. Hold the tail wheel
assembly up to the fuselage as shown and mark the location
where the wire will insert into the rudder. Remove the rudder.

Step 3.

Using a 3/32" drill bit, drill the rudder following 

the marks you made in the previous step. Make sure to drill
straight into the rudder.

Hint:

Use a piece of masking tape on the drill 

bit as a depth gauge to avoid drilling too deep.

Step 4.

Use a sharp hobby knife to make a notch in the bottom

portion of the rudder to accept the tail wheel wire and allow 
the rudder to seat properly against the vertical fin. Tests fit the
rudder and tail wheel assembly to the vertical fin and make
adjustments until there is only a slight gap (1/32" or less) at 
the hinge line.
