Racekraft 5051 Triblade Propeller. Designed from the bottom up to maximize performance and control.

This triblade was designed to meet the Betz condition for maximum efficiency at 60mph, with bursts of 80+ MPH on certain set ups . This isn't efficiency in terms of flight time, however how efficient power is delivered to the flow.

3D aerodynamic models were built using potential flow theories and verified using CFD software. Blade flex was also considered and utilized to maintain a linear throttle response through most of the range of your stick. We slightly changed the number convention to be used with our props. The last 2 digits of 5051 does NOT mean pitch as were with previous props.

Racekraft has named this prop 5051, but in actuality it sports a static pitch angle of 4.4
