Blades are molded from tough composite material
and mounted with roller type thrust bearings.
All steel parts are plated. Blade pitch is
controlled through a push-button type vernier
control cable. Blade design attains high
power input to the pump. Adapts to most pumps
and aircraft in use today. Requires removal
of present fan and brake assembly, plus the
drilling and tapping of a retainer cap screw
hole in the end of the pump shaft. The control
cable is installed according to individual
desires but must be securely mounted. Blade
full feather instantly to stop the pump.
No brake is required. In the feathered position,
drag is cut approximately in half as compared
to standard plastic multiblade or wooden
fans. Fuel savings will eventually pay for
the fan.
