9. Fit the vertical fi n onto the fuselage and use a felt-tip
pen to trace around it onto the fuselage. Remove the covering
1/16" [1.6mm] inside the lines you drew.
10. Use 30-minute epoxy to glue the fi n into place. Be sure
to put a coating of epoxy along the entire underside length of
the fi n as well as the side of the tabs. Wipe away any excess
epoxy with denatured alcohol. Use a triangle or measure to
confi rm that the vertical fi n is installed perpendicular to the
horizontal stabilizer. If necessary, use tape to hold the fi n
square while the epoxy cures.
11. Trim the covering from the tail servo pushrod exits on
the left and right sides of the fuselage. Temporarily insert
a 29-1/2" [749mm] pushrod into the elevator outer pushrod
tube that exits the left side of the fuselage. Use the position
of the pushrod to mark the location for the elevator control
horn onto the underside of the elevator.
12. Drill 5/64" [2mm] holes at your marks through the
elevator. Apply a couple drops of thin CA to each hole to
harden the surrounding wood. Install a control horn and
backplate onto the underside of the elevator using two
2x20mm machine screws.
13. Install a control horn onto the right side of the rudder
in the same manner.
