Gday, Bolly props are really popular here in Australia for good reasons. They are a very efficient and well-made prop. But they aren't solid carbon fiber like the Warp Drive. I can verify that from a recent prop strike by a friend..... But I like that construction because they are much lighter than a Warp Drive which makes for smoother running. Still plenty strong enough for flight ops. And for a ground strike I'd prefer a prop that shattered and protected the gearbox.... I did very thorough prop comparison tests on a bunch of different makes some years ago and these are the results: https://www.stolspeed.com/nid/46 JG ________________________________ Message 2 _____________________________________ Time: 09:06:22 AM PST US Subject: Kolb-List: Re: Bolly Props? From: "13brv3" <13brv3@gmail.com> Nice job on the review. I read that in my initial searching. It's odd that with all the different prop types, the measured performance was so similar. I guess the Bolly is "solid" but not all CF. It looks like they have some sort of micro-balloon core, which is probably a compromise between hollow (or foam) core, and solid CF like Warp. The light weight is nice, but their really peformance benefit is probably smoother operation, and lower noise. I'll almost certainly just stick with the 3 blade Warp I have for now, and maybe try something else later.
