This product was added to our catalog on November 18, 2016.The designers of this particular Racekraft 5051 prop is an industry first in that it is truly optimized for speed. Typically Racing Drones are flying anywhere from 40-60mph on average, with bursts of 80+ MPH on certain set ups. With this critical bit of knowledge, the 5051 prop was designed to bring maximum aerodynamic efficiency at 60MPH.
Throw out the thrust data you're accustomed to seeing, as these props are not going to take the crown for any "static" thrust tests strictly due to their design!
Racekraft has named this prop 5051, but in actuality it sports a static pitch angle of 4.4".
One of the first things pilots notice is the aggressively raised blades & tips above the hub, and are nearly 1 inch higher than the prop hub. Thanks to aerodynamics, Racekraft has designed this prop to give massive amounts of bite at the first inch outward from the hub. This is due to the airfoil spinning at a much slower rpm than the tip of the prop.
Such designs are inherently going to provide more thrust across the entire length of the prop, instead of just near the tips. Additionally the extreme blade tips feature an upturned wingtip device, which aids to increase efficiency while minimizing prop vorticies.
NOTE: Due to the aggressive blade design, and the height of the blade tips, some racing drone frames will encounter contact between the frame & the prop tip.
