 Step 5
Secure the throttle servo in the fuselage using the
hardware provided with the servo. Thread a clevis onto the
threaded rod and attach the clevis to the servo arm.
Note: When using a gas engine it is
recomended that an RF choke ring (JRPA029)
be used. The servo lead must make 3
passes around or through the ring.
 Step 6
Remove the stopper from the fuel tank using a Phillips
screwdriver. Remove the fuel lines from the stopper and
set them aside. Prepare the tubing by placing a drop of
solder on the ends of the brass tubing as shown. This
will keep the fuel line from slipping off the tube when
combined with the following steps.
 Step 7
Slide gas compatible fuel lines back onto the brass
tubes. Use fine wire to secure the fuel lines. The wire
is placed behind the solder applied in the previous step
to keep the tubes in place.
 Step 8
Carefully insert the stopper assembly into the fuel tank.
Note the position of the vent tube; it must be up at the top
portion of the fuel tank to function properly. Tighten the
screw carefully—do not over-tighten.
