This page contains a chart of carbon fiber props 12″ inches in diameter and over from 2 common vendors. I created the page to fill a specific need for a project I was working on. If you’re reading the blog and have a need for such info, then read on. If not, feel free to skip it.
This is the cf-props chart. I hope you find it useful. This has no guarantee whatsoever. Use at your own risk. You are completely and totally responsible for your vendor and product decisions.
Copy the text below the following horizontal line into a separate text file with fixed pitch character spacing so the columns line up. This may look like gibberish at first since most web browsers use proportionally spaced fonts and / or scrunch the chart to a narrower width. But, if you copy it into something like notepad (in Windows) in a simple text file with a fixed space font, it should work. Printing it may be a challenge with notepad, but if your text editor can scale printouts, you should be able to print it on one page. On my pc, I was able to display the chart all at once on a 1366 x 768 screen, capture a screen image, then print that, just because I didn’t want to worry with other text editors besides notepad (which cannot scale printouts).
The chart shows the results of a simple search through the website inventory of two vendors, on the date listed, for carbon fiber propellers 12″ in diameter and over. The vendors are http://www.hobbyking.com/, designated by H; and https://www.foxtechfpv.com/, designated by F. This does not imply an endorsement of these vendors or their products. They are simply two vendors I’m familiar with. The chart is not comprehensive nor is it exhaustive. As soon as you print it, it’s obsolete, like all printed things. It will likely not be updated as it was created for a specific project. It lists big props because that’s what I needed at the time.
If you are creating an RC aircraft and need a certain propeller based on your calculations, you may find that the one you want is not readily available on the market. For example, a 20″ x 4″ carbon fiber prop is not available from either of these vendors. Keep in mind that this is just a snapshot in time. The prop could become available tomorrow. You should not assume that 20″ x 4″ props are not available anywhere on the planet. What you can assume, if I didn’t make any typos, is that where it says something IS available, that it was available on the date the chart was originated.
NOTE – Pitch numbers are rounded to the nearest .5″. So, if it says a 22″ x 5.5″ prop is available, it COULD be a 22″ x 5.7″ prop for instance.
To use the chart, find the prop diameter you want to use on the left column of the chart. Follow that line horizontally to the right until you find the column of the pitch you want. If the prop is available from Foxtech, you will see an F in the grid where the row and column intersect. If the prop is available from Hobbyking, you will find an H. If it was not available from either vendor, the grid will be blank at that point.
Good luck with your design.
Sincerely
Ron
