Sorry HK, but these are simply not fit for purpose.
I thought I'd give them a try on my 250 Quad (3S, with Multistar 2206-2150 v2 motors).
Throttling up gently on the bench and you can hear some nasty vibrations.
Putting this under an artificial light (50Hz) and you can see a ~20mm high standing wave setup by the propeller disc. The disc should be flat.
I'm afraid that these fall into the same category as the 6030 gemfan props that resonate and self destruct when under load / high RPM.
I am not prepared to put these in the sky to find out!
0 crowns.These props are horribly out of balance and very noisy. I tried 2 yellow and 2 green of these and the vibration is horrible on all 4 props. Even though they are cheap and pretty, I would not recommend these for your multi copter. The other 3 bladers i tried are Gemfans which are much better.these props are awesome and go along well with the scorpion motors also because of their yellow color scheme, great prop for beginners, i recommend buyingSolid product,works well.
