❏ 12. Connect the pushrod to the servo with a nylon
Faslink. Note: If necessary, enlarge the hole in the servo
arm with a 5/64" drill bit (or a #48 bit for precision). Let the
pushrod locate the servo (left to right), in the servo tray,
then screw the elevator servo in place.
❏
13. While keeping both elevators centered, connect the
two elevator pushrods to each other with two 5/32" wheel
collars and 6-32 x 1/8" set screws as shown in the photo.
We recommend using thread locking compound on the set
screw threads.
❏ 14. Mount the rudder with the hinges the same as you
did with the elevators.
❏
15. Mark the location of the tail gear wire on the rudder
and the nylon tail gear bearing on the fuselage.
❏
16. Remove the rudder and drill a 7/64" hole in the LE of
the rudder at the mark you made for the tail gear wire. Cut
a groove in the LE of the rudder for the nylon tail gear
bearing. Test fit the tail gear wire in the rudder.
❏
17. Cut a slot in the trailing edge of the fuse at the
marks you made for the nylon tail gear bearing. Without
using any glue, join the rudder to the fin with the tail
gear wire in position.
❏
18. Mount the control horn to the rudder, trapping the tail
gear wire between the screws.
❏
19. Hook up the rudder pushrod the same as you did
with the elevators.
❏ ❏ 20. Mount the aileron servos in the wing with the
screws provided with the radio.
❏ ❏
21. Locate the control horn on the aileron using a
square so that the pushrod will be perpendicular to the
hinge line. Mount the control horn and back plate with the
2-56 x 5/8" screws.
❏ ❏
22. Screw the clevises twenty turns onto the 8-1/4"
pushrod and the 9-3/8" pushrod.
