Section 7: Hinging The Elevator And Rudder - Hangar 9 Alpha Trainer Assembly Manual

Section 7: Hinging the Elevator and Rudder

Parts Needed
• Fuselage assembly
• Elevator
• Rudder
• Hinges (7)
Tools and Adhesives Needed
•Thin CA
• CA remover/debonder
• T-pins
• Rubbing alcohol
• Paper towels
Caution: The hinges included with the Alpha™ Trainer
ARF are made of a special material that allows the thin
CA to "wick" or penetrate and distribute throughout the
hinge, securely bonding them to the wood structure. It is
imperative that you properly secure the hinges in place per
these instructions using high quality thin CA glue.
Step 1
Locate the four elevator hinges, place a T-pin in the center of each
hinge and slide them into the horizontal stabilizer until the T-pin
is snug against the trailing edge as shown.
Step 2
Install the elevator onto the hinges. Remove the T-pins and push
the elevator up against the stabilizer until there is only a slight
gap (1/32" or less) at the hinge line.

Step 3
Using high-quality thin CA glue, deflect the elevator down and
completely saturate each hinge.
Step 4
Turn the fuselage over and repeat the hinge-gluing process by
deflecting the elevator in the opposite direction and again
completely saturating each hinge with thin CA. Wipe away any
excess CA with CA remover/debonder and a paper towel. Allow
the CA to completely dry.
Step 5
Once the CA has dried, check the hinges for security by trying to
pull the elevator from the stabilizer. Use only slight pressure and
be sure not to crush the wood structure of the stabilizer or elevator.
