plate is integral to the fin structure and the mounting
holes are pre drilled for you. Before installing the
servo make sure it is centred and fit a high strength
servo arm (aluminium or carbon reinforced is
recommended). A 10 - 11mm arm is the maximum
size that will fit in this area. This length of arm will
give plenty of rudder throw. Again before installing
the servo in the fin attach the metal ball link
supplied with M2 screw and nut, securing with
loctite. Now you are ready to install the servo in the
fin with 4 of 2.9 x 13mm sheet metal screws. You
will find you need to attach a short extension lead -
100mm or so to the rudder servo.
Taking the 105mm M3 threaded rod supplied for the
rudder pushrod, screw on one of the M3 ball links
supplied to one end. For the next step you might
find it easier to remove the rudder form the fin. This
is done by simply pulling out the piano wire hinge
from the bottom of the rudder. This will give you
access to screw the open end of the pushrod
through the rear of the fin and into the ball link
attached to the servo arm earlier. Take note from
the pictures that the rudder pushrod is operated on
a "diagonal" plane to give the best throws without
any binding.
Re-attach the rudder ensuring the piano wire has
not missed any of the hinge points and affix the
rudder ball link with M3 x 15 allen screw and nyloc
nut.
The fin assembly is secured to the fuselage using
the supplied aluminium spar which you will find is
pre drilled and fitted with an M3 captive nut for
securing inside the rear of the fuselage - see figure
31.
