King Air C90 EPIC


C90 Swept Blade Turbofan Propellers (SBTP)

Why sweep the propeller blades?

The biggest benefit of propeller blade sweep for the King Air type of airplane is that it allows for a larger diameter propeller that provides greater thrust without increasing the sound level in the airplane and on the ground. Raisbeck's Swept Blade Turbofan Propellers for 90-Series King Airs provide unparalleled performance increases across the entire flight envelope. The Swept Blade Propellers as part of Raisbeck's EPIC Performance Package creates the best-equipped C90/B90/A90 in the field.
