Another new prop design, but one that is actually quite innovative. The Foxeer Donut prop 5145 is a ring-shaped prop, also known as a toroidal propeller. Its design aims to minimise noise without compromising on efficiency. The sound profile of this prop is certainly different to a traditional 5-inch tri-blade. In our opinion while they aren’t dramatically quieter, their sound profile is wider and the high pitch squeal is reduced. In terms of performance, they don’t feel inferior to a regular blade and may have some efficiency gains. Its compact shape also has the bonus of being more travel friendly than a regular prop and it is marginally lighter too.
For those who like experimenting with new setups, this prop has been made for you.
