Suggesting a Prop Size Calculator Tool for DIYFPV
@tpetersons @uavfutures I just watched the new livestream clip from Joshua B. in which he talks about how to choose prop size... after that i used google to look if some sort of calculator exists.. well there are multiple available... but i think it would be amazing if you include such a tool on DIYFPV! The one i like the most because its fairly simple to figure out what you need or want to achieve is this one:

Always open for new ideas 🤗 will discuss in our next meeting. Appreciate the suggestion @M4R5_FPV 👌

I checked out that tool. It does look cool but the real world use would probably be pretty low. On the back of a lot of prop packets they often have some sort of graph that shows power, thrust etc But it is all pretty insignificant data etc. a drone changes speeds and directions so often that there is no real efficiency band. This calculator also doesnt seem to show the drag etc which will make a massive difference, and how does that drag change as the angle of the drone increased as it rockets towards the horizon. how far apart are these props, what is the aerodynamics of the frame. these rest of the numbers are pretty meaningless unless you have this data to go with them. And if you do have that wind tunnel data... how much does this really change how you fly.
this calculator would be useful for things like trying to max speed run, or longest flight time but for most pilots is could be a number trap. like trying to change some tiny pid settings to improve a lap time when the best thing you could do is instead just get a few more packs in and practice flying.
I dont know. Would you use it often? We want to build amazing things for the community but we only have x amount of resources and need to focus on specific things.
PS your parts in the builder are AAAwesome

I absolutely agree that for the most pilots its pretty much useless but to some extend it can be useful to showcase flight time with different prop pitches or sweet spot for a certain frame size. Which prop size or pitch would be better if someone wants to fly doing cinematic shots compared to someone who wants to fly freestyle or someone who is a racer. Of course a lot of data goes into it as you mentioned. So it would be more a theoretical tool than a "real world" calculator.
No worries It was just an idea 😜 I thought of it like the FPV goggles comparison tool.
