FPV hobbyists, gather around. We're about to delve into an insightful video shared by none other than KremerFPV, as he explores the peculiarities and promises of the Foxeer Donut 5145 5-inch propellers. Echoing the design principles of MIT's toroidal propellers, these gems aim for a quieter flight without skimping on efficiency. Join us as we unpack KremerFPV's observations about the propellers' design, performance, durability, and their frost test results. If you're all about pioneering FPV gear, this is a must-read!

Foxeer Donut 5145: An Overview

As we unwrap the new Foxeer Donut 5145 propellers, we see them packaged in sets of four and available in two appealing colors—teal and crystal black. Each propeller weighs in at a modest 4.2 grams, slightly lighter than your average tri-bladed 5-inch propellers. So, what's the big deal with these propellers? Well, they're based on the toroidal propellers from MIT. If that term is new to you, the purpose of toroidal propellers is to bring down the noise levels while keeping up the same efficiency as regular propellers.

Performance and Durability

During his hands-on test, KremerFPV confirms the propellers' unique acoustic signature—they're not silent, but they don't make as much noise as their traditional counterparts. They also score extra points for being travel-friendly due to their compact design. And as for durability, even though KremerFPV hasn't had any crash incidents yet, his initial impressions hint at a robust and sturdy build of these propellers.

Efficiency Examination

As any seasoned FPV enthusiast would, KremerFPV puts these propellers through a rigorous frost test to evaluate their performance. From his findings (which we've included below), it appears the Foxeer Donut propellers align well with traditional propellers when it comes to performance. The significant takeaway is that despite their innovative design, they don't falter on the performance front.

Verdict: Are They Worth a Spin?

Given their affordable price, KremerFPV suggests that those who love to experiment with their FPV gear should consider ordering a set, or even two. Try them out, and decide whether they mesh well with your flying style. While the Foxeer Donut propellers might not revolutionize your flights, they do offer some interesting attributes that could spice up your FPV experiences. Wrapping up with the flight footage below, we invite your queries and comments, as always. Here's to enjoyable flying, and stay tuned for our next exploratory post!
