The servo mounting
plate. HiTech HS-225MG servos were used.
Spruce
stiffeners and hole reinforcements added to the bottom of the plate.
Installed.
A
control horn was cut from 1/16 G10/FR4 laminate (circuit board
material) and installed in the rudder, blocked in by scrap balsa
sanded to blend with the rudder.
Another
view. The holes for the clevises should line up with the pivot
pin in the rudder.
A
3/16 carbon fiber tube was used to make a rudder push rod. 2-56
threaded wire was inserted in the end with a 90 degree bend that
extended through a hole drilled 1 inch from the end of the tube to
lock it in place. A channel was ground on the opposite side of the
tube which allowed the wire to be inserted. The inserted
wire and channel was filled with gel CA and wrapped with carbon fiber
tow secured with thin CA. The rudder bellcrank connectors
are made from brass rod ends soldered to small wire terminal ends that
have had the insulation removed. Kevlar thread will be used for a
pull pull rudder control.
