Step 7
Attach the clevis to the outside hole on the elevator control
horn. Thread the clevis in or out so the elevator is centered
when the bellcrank is centered. (See hint below to center
the bellcrank.) Once both are aligned, tighten the 3mm nut
against the clevis to keep it from vibrating and changing
position.
Important: Make sure to use threadlock on the locking
nut to prevent it from vibrating loose.
Hint: Slide the hex wrench through the ends of the
leadout wires. Lightly pulling on the wrench will bring
the bellcrank to the center position.

Step 8
Place the bellcrank hatch back in position on the bottom
of the wing. Use a drill and 1/16-inch (1.5mm) drill bit to
drill four holes in the corners of the bellcrank hatch. Use a
#0 Phillips screwdriver and four 2mm x 10mm sheet metal
screws to secure the hatch to the fuselage.

Step 2
Insert a 1/2 ounce (14 g) weight into the tip weight box to
start. You can adjust the amount of weight later depending
on your particular flying style, but we have found this to be a
very good starting point.
