Legacy propellers no longer in production, but we are still supporting them for parts and service..

HRT 2-Blade Series
The 2017 class of 2 blade high speed, high performance propeller systems feature a wider tip “scimitar” blade shape incorporating Whirl Wind proprietary technology of thermoset carbon fiber over a high density foam core. Cutting edge airfoil designs for high speed that also deliver exceptional cruise performance.

HRT / 3-Blade
The 2017 class of 3 blade high speed, high performance propeller systems feature a wider tip “scimitar” blade shape incorporating Whirl Wind proprietary technology of thermoset carbon fiber over a high density foam core. Cutting edge airfoil designs for high speed that also deliver exceptional cruise performance.

284 STOL Constant Speed
The large diameter 284 propeller develops outstanding low speed thrust equaling exceptional short take off performance and shorter landing distance due to its braking effect. This performance as well as solid nickel leading edge erosion shields make the 284 the perfect back country constant speed propeller system.

200AC/400AC Aerobatic
The 200AC / 400AC high performance counterweighted aerobatic propeller systems feature “scimitar” blade shapes incorporating Whirl Wind proprietary technology of thermoset carbon fiber over a high density foam core. Aggressive airfoil designs for aggressive, unlimited class aerobatics.
