Kevlar
thread
is used for a pull pull rudder setup. Spectra wire also is good
and is available at fishing supply stores. Kevlar is available
from industrial
sewing thread suppliers. Multiple square knots are tied and then
glued with thin CA at this end. Loops are also
formed at the rudder
end and the final attachment is with loops of fine wire twisting the
free ends of the wire to tighten the loops
and establish tension
to trim the rudder at neutral with the servo powered up at
neutral. It is easier to
do the loops on the servo arm before
the arm is on the
servo when your fingers are as big as mine. I do this before the fuselage is covered
and then leave the Kevlar
long, pulling
it through the exit points on the aft fuselage while I am
covering. After the covering
is done I do the rudder end attachments.
Windscreen and front
rubber band post. Also in view is an adapter plate I made on my
firewall allowing different power arrangements. The
ply plate attached to
the firewall with screws and nut plates. There are embedded nut
plates in the ply plate for the Cox mounting
screws which are
short enough to not reach the firewall.
An ounce or so of
weight is in the nose.
