STEP 5: ASSEMBLING AND INSTALLING THE FuEL TANKS
STEP 6: HINGING THE RuDDERS
Both rudders have a preinstalled plywood control horn mounting plate in the lower inside surface. You can see it just under the
covering material. Make sure that when you hinge the rudders, that the plywood plate is toward the inside of each fuselage boom.
STEP 7: INSTALLING THE RuDDER CONTROL LINKAGE ASSEMBLIES
❑ Cut out the molded rudder pushrod exit slot in the back of each fuselage boom.
❑ Assemble each of the two fuel tank stopper assemblies, using one
straight tube and one 90º tube. The straight tube is the fuel pick-up tube
and the 90º tube is the vent tube.
☞
One of the 90º tubes included is not used.
❑ Install the stopper assemblies into the fuel tanks, making sure that
the 90º vent tubes are positioned toward the top of the fuel tanks.
☞
Check the lettering on the side of the fuel tanks to determine the top.
The lettering should face up.
iMpoRTANT Double-check to make sure that the clunks can move
freely inside the fuel tanks.
❑ Install the fuel tanks, making sure that the top of the fuel tanks are
toward the top of the fuselage booms. The front of the fuel tanks should
fit firmly in the predrilled hole in the firewalls.
iMpoRTANT Make sure to secure the fuel tanks firmly into place and
double- check that they don't interfere with the throttle linkages. Silicone
sealant works well to secure the fuel tanks into place.
❑ Hinge one rudder to each fuselage boom, using two plastic hinge
points and 5 minute epoxy. Make sure to push the hinges' pivot point
completely into the notch in the rudder to ensure a tight hinge gap.
❑ Slide one pushrod guide tube through each slot, making sure that
the front of each guide tube passes through the space just below the
wing mounting plate, then glue the guide tubes to only the back of the
fuselage for now. Allow approximately 1" (25mm) of each guide tube to
extend out from the fuselage boom side.
❑ Install the two threaded pushrod wires, two control horns, two clevises
and four wood screws provided.

IMPORTANT Apply Vaseline or machine
oil to the hinge pivot points to keep from
gluing the hinges solid.
