Here are some thrust results for triple-blade propellers. I ordered and gathered as many as I could of available triple-blade props. I used an EMAX RS2205-2300KV motor and 4S LiPo batteries. My thrust stand is not the most accurate device, but for comparing propeller and ESC/motor setups it does an acceptable job. I have recently ordered the RCBenchmark 1520 thrust stand for future tests.
Hope these tests results may be of some interests to you:

Thanks Ocie! I really appreciate your Thanks :) and it's great to see tests help people decide on setups.
Thanks EngineerX,
Thanks again for all of the testing and logging you do. I can't imagine how many people have benefited from the data you have collected over time, but I am sure you don't get thanked enough. So THANK YOU!
Thank you guys
@Doug Walmsley It should be in the video description, it's a Dropbox link https://www.dropbox.com/s/dofxqmb93grbh7k/thrust%20results%20Triple...

@Maxime Chambonnet That's a subject I would rather leave in the hands of a aerodynamics/aerospace/mechanical engineer or anyone else with enough knowledge on the subject. I only know the very basics. Here are a couple of links with some interesting info: http://www.stefanv.com/rcstuff/qf200203.html (Three or more blades - about halfways down on the page)

Hello and nice work, would you have resources discussing and comparing dual and tri-blade aerodynamic properties?
EngineerX,
Nice test video. I'm preparing to build a FPV racer and this is insightful. However, I was not have any success locating you excel spreadsheet that you mentioned in this post. Would please provide a link to it?
