Brilliant racing props, exceptional thrust in negative AoA. These things have a feel like they 'cut' better entering hairpins, split-S, and corkscrews. Hard to describe beyond that, but that's the dominant characteristic that makes them such an excellent race prop.
Needs some forward speed or a light prop to be efficient - thrust is basically identical to DAL T5046C in static cases, though these have a bit more up top (at the slight expense of efficiency and resolution under 40% throttle).
Durability is very good, but not great. Clear are the toughest, the darker colors (purple especially) flex a touch easier, but also can be bent back after moderate crashes easier. I'm happiest running clear, and I've been getting my best race results running these.
