Step 6: Rudder Servo installation (optional)
Skip to step7 if you do not wish to install a working rudder
After the epoxy has cured, turn the model
around. The pushrod sleeve should now
protrude into the fuselage similar to the
picture above. It will point towards the left
or right fuselage wall.
The wall it is closest to, will be the rudder
servo installation wall. Due to the tight fit
between fuselage and duct, the servo needs
to be shifted slightly forward of the fan
unit.
If it is not done yet, roughen the sleeve
with sandpaper. Next glue it in place along
the fuselage side. Use 5min Epoxy. (Also
look at the next picture to see how the end
of the sleeve is positioned against the fan
mount). Use balsa scraps on both sides of
the sleeve to improve the bond. You can
use scrap wood dowels to push the sleeve
against the fuselage wall as shown. Once
the epoxy has cured these braces are
removed.
The end of the sleeve will be glued against
the bottom of the fan mount. Again use a
piece of balsa scrap to wedge it in place.
Once the glue is dried, shorten the sleeve
inside the fuselage, directly behind its glue
spot on the fan mount. Insert the pushrod in
the sleeve. Leave 30mm space between the
threaded end and the end of the sleeve in
the fuselage. Cut the pushrod at the end of
the rudder.
Mark the rudder horn position (the line of
holes in the horn should line up with the
pivot point of the rudder) and drill the
holes. Secure the pushrod to the rudder
horn with a z-bend. Insert the z-bend before
you fix the horn in place.
Use masking tape to fix the rudder in
neutral position.
