Propeller damper cooling (F250G and FL250G)
The water pipe for cooling the propeller damper is incorporate
d in the lower case. The water intake
is located in front of the trim
tab to drawn in the wate
r by the dynamic pressu
re, and the propeller
damper is cooled without disturbin
g the exhaust gas flow. As a result,
higher output can be
obtained.
