Secure the Steering Pushrod Tube:
❏
7. Using the scrap plywood from the servo tray, install
a brace for the steering pushrod tube. Use medium CA
to attach the brace to the fuselage side. Medium CA is
also used to attach the tube to the brace.
Prepare the Pushrods:
❏
8. Locate the two wooden dowel pushrods and apply
thin CA to the ends of the shrink tubing on both rods.
Locate the Rudder Exit:
❏
9. The rudder pushrod exit is located on the top of the
fuselage on the left side of the fin. Carefully remove the
covering from the opening using a sharp hobby knife.
Position the Rudder Control Horn:
❏
10. Carefully remove one of the nylon control horns
from the nylon parts tree. Position the horn so it is 7/8"
(22mm) above the elevator and on the same side as the
pushrod exit. Using the illustration, position the horn so
the holes align along the hinge line of the rudder and fin.
Mark the positions of the holes on the rudder using a
felt-tip marker.
Attach the Rudder Control Horn:
❏
11. Drill the locations marked in the previous step
using a 3/32" (2.5mm) drill bit. Place two 2mm x 16mm
machine screws into the control horn, and slide the horn
and screws into the holes. Remove a control horn
backing plate from the nylon parts tree, and thread the
screws into the plate on the opposite side of the rudder.
Tighten the screws, but not so much that you crush the
balsa. Cut-off the excess screws extending past the
backing plate.
