Step 3 Install rudder horn (L&R) and hinge rudder to the fin
Figure 4. Install rudder horn and then hinge the rudder to the fin
▼
1. Install control horn (L&R) onto the rudder. A small amount of the rudder horn may need to be cut
away to allow for more left and right movement.
▼
2. Apply CA to glue hinges into the rudder and the fin. Make sure that the rudder moves freely.
IMPORTANT
To achieve maximum movement (up to 80 degrees) on the rudder it is necessary to fix the rudder horn so
the clevis holes are 5mm behind the hinge line.
Step 4 Install the elevator horn and glue the hinges to the stabilizer
Figure 5. Install elevator horn and hinge it to the stabilizer
▼
1. The elevator horn must be mounted slightly off centre, allowing the push rod to pass one side of
the vertical fin post.
▼
2. A small amount of the elevator horn may need to be cut away to allow for more down elevator.
Check movement each way and trim if necessary.
▼
3. Fit the elevator push rod using the metal link at the elevator end and the bent wire with a swing
keeper at the servo end.
