Vertical Stabs and Rudders
Begin by gluing rudders into vertical stabs as
follows: fill the hinge point holes in one
vertical stab with a generous amount of
Aeropoxy. Insert rudder. Install vertical stab
into the fuselage and temporarily tighten
mounting bolts. Move the rudder inward to the
point where it just contacts the exhaust tube
on the fuselage. Press the rudder forward such
that it contacts the hinge cover equally along
its length. This will set the appropriate depth
of the hinges. Visually check for even spacing
along the length of the hinge line.
Repeat for the other side.
When the glue is dry, remove the vertical
stabs.
As with the elevator servos, locate neutral and
install servo arms.
Drop the servos into their pockets, oriented as
shown, route servo wire to the bottom of the
rudder, and secure with screws. Use masking
tape on the drill bit to make sure you do not
drill all the way through the stab when
installing screws.
