Tech Notes
 
NOTES FROM OUR TECH DEPARTMENT
This flexible tubing replaces your existing header and allows you to
reroute your silencer farther away from the engine or cowl.

This ONLY fits the following engines:
FS-90 (old), FS-120 (old), FS-70 Surpass, FS-91 Surpass, FT-120 II
FT-160
Features: Uses the silencer that came with the engine (it replaces the header)
Comes in 2 lengths 120mm (OSMG2684) and 240mm (this one)
Reroutes the exhaust to a more convenient location

Includes: One Flexible Exhaust Tube (male threads on both ends)
Two Pipe nuts

Specs: Length (neglecting threaded part): 240mm (9.45")
Length (overall): 263mm (10.35")
Thread Size on Nut: 10.5mm
Diameter of Flex Pipe: 12mm (.47")
*** SCROLL FOR MORE INFO ***
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 (OSMG2624) and
a "outside fuselage" configuration (OSMG2625).
