5x4.3 bullnose prop

thingiverse

Someone requested a 4.5 pitch version of my original 5x3 bullnose prop design, so here's how close I was able to get it. Although I designed them as 4.5 pitch, my pitch gauge tells me the finished result is 4.2-4.3; the flat edges of this design make the gauge clamping awkward, but let's face it - there's only a 0.2 difference if my gauge is reading correctly anyway.

To be honest, I probably wouldn't have bothered upping the pitch if someone hadn't asked and I got curious, so I decided to give it a shot. Personally, I'll stick with the 5x3's as they've shown more than enough thrust, responsiveness, and durability so far - but if you want to try these 5x4.3's, I can at least say they work just as well as the 5x3's if nothing else. I haven't been able to test them at full pace straight runs like my 5x3's because it got dark before I could, and my testbed frame has no orientation lights; flying something that fast in dim light with no lights is plain stupid.
