     This flexible tubing replaces your existing header and allows you to
         re-route your silencer farther away from the engine or cowl.
     This ONLY fits the following engine(s):
        FS-120 surpass (with and without pump) and FS-120 Surpass SP

Features: Uses the silencer that came with the engine (it replaces the header)
          Reroutes the exhaust to a more convenient location

Includes: One flexible exhaust tube
          Two pipe nuts
          One pipe adapter (OSMG2629)

Specs:    Length (neglecting threaded part): 240mm (9.45")
          Length (overall): 280mm (11.02") (INCLUDING the exhaust adaptor)
          Thread Size on Nut: 10.5mm at one end and 13.5mm at the other
          Diameter of Flex Pipe: 15mm (.59")

Comments:
   This pipe should NOT be bent in a diameter that is less than 4 times the
      radius of the pipe (44mm or 1.73")
   Bends in the pipe should be as far as possible AWAY from the threaded part
      of the pipe. Final adjustment should be made in steps of only 2-3° at
      a time. Repeated adjustment to alter the shape of the pipe will
      weaken the pipe and cause it to break.
   It is recommended that you use the EX exhaust headers with this flex pipe
      if you need a bend right at the exhaust outlet on the cylinder head.
      These are available in a "within fuselage" configuration (OSMG2622) and
      a "outside fuselage" configuration (OSMG2623).
                                                                    JBN 3.28.94
