COMMENTS: Recommended is a 450-550cc fuel tank that allows approximately
            10 to 12 minute flights.
          Locate the fuel tank so that the top of the tank is 5-10mm (1/4-3/8")
            above the level of the needle valve.
          A 1/16" wire (not included) can be used to extend the needle valve by
            inserting the wire into the pre-drilled hole on the end of needle
            valve and tightening it in place with the supplied set screw.
          Remote needle valve is held in place by a nut instead of screws.
          To use a Tru Turn spinner and an APC propeller, modeler will need
            the Tru Turn jam nut set TT-0378-A (not carried at this time).
