Section 7: Hinging The Rudder

Items Needed
Fuselage from Section 6
Rudder
Rudder hinges (4)
Tail wheel assembly
1. Trial fit the rudder in position with the four hinges in
place. Note that the three hinges attach to the fin, while
one hinge attaches the rudder to the fuselage.
2. Insert the tail wheel wire into the pivot bushing. With the
pivot bushing resting against the bend in the tail wheel
wire, use needle nose pliers to make a 90° bend in the
direction shown, 1/8" above the top of the pivot bushing.
3. Hold the tail wheel assembly up to the fuselage in the
correct position. Temporarily mark, with a felt tipped pen,
the position where the hole is to be drilled into the rudder.
Also mark the position of the slot where the pivot bushing
will fit into the back of the fuselage.
