Section 7: Installing The Rudder - Hangar 9 Twist 3D .40 Assembly Manual

Section 7: Installing the Rudder

Required Parts
• Fuselage assembly
• CA hinge (3)
Required Tools and Adhesives
• Thin CA
• 6-minute epoxy
Step 1
Locate the last three CA hinges, and place T-pins
in the center like we have done for the ailerons
and elevator.
Step 2
Install the hinges in the rudder.
Step 3
Test fit the rudder to the fuselage. Make sure the tail
gear wire goes into the rudder, and that the rudder
will rest tight against the fin and fuselage. The tail
gear bearing should not interfere with the rudder.
• Rudder
• T-Pins
Step 4
Mix 1/2 ounce of 6-minute epoxy. Remove the
rudder, and place the epoxy only in the hole, not in
the groove. Epoxy in the groove will probably make it
difficult to use the rudder. Install the rudder as
described in the previous step.
Hint: You can combine the previous step with
the following step if you like. This will hold
the rudder in position while the epoxy cures.
Step 5
Check to make sure the rudder moves freely. It
should not rub against the fin at the tip. Apply thin
CA to both sides of the hinge. Make sure to
saturate the hinge, and don't use accelerator.
Use a paper towel and CA debonder/remover to
clean up any excess CA.
Step 6
Once the CA and epoxy have fully cured, give
the rudder and fin the tug test to make sure the
hinges are well glued. Flex the rudder a few
times to break in the hinges.
