Section 7: Installing the Rudder
Step 2
Drill the location marked in the previous step using
a 1/8" drill bit.
Step 3
Use a hobby knife to cut a groove for the tail
wheel wire into the leading edge of the fin from
the hole to the bottom of the rudder. Also cut
a small notch to allow clearance for the tail wheel
wire support bracket.
Step 4
Use medium sandpaper to roughen the portion of the
tail wheel wire that will be inserted in the rudder.
Step 5
Locate two CA hinges and place a T-pin in the center
of each hinge. Place the hinges into the rudder.
Step 6
Test fit the rudder to the fin and tail wheel wire.
The gap between the rudder and fin should be a
maximum of approximately 1/64".
Step 7
Check the movement of the rudder to make sure it
clears the fin.
Step 8
Remove the rudder from the fin. Mix 1/2 ounce of
30-minute epoxy and apply it to the groove and
hole in the rudder. Insert the rudder control rod.
Remove any excess epoxy using rubbing alcohol
and a paper towel.
Note
: You can combine the previous step with
the following step if you like. This will hold
the rudder in position while the epoxy cures.
Important
: Do not let epoxy get into the tail
wheel wire support bracket.
Step 9
Check to make sure the rudder moves freely. Apply
thin CA to both sides of the hinge. Make sure to
saturate the hinge and don’t use accelerator.
