Very thin and flimsy.

Very thin and flimsy.

The manufacuring tolerance seems insuffizient - I received CW/CCW 1 pack each - the blade tips end (measured from flat surface) at 4 mm, 8 mm and 11 mm - but they should be exactly at the same level! The power is about 1/2 of a 2-tip-prop from GWS or APC.
Schlechte Fertigungstoleranz - groe Streuung - wenig Power.

really soft material. bends and cracks easily. this is for lighter planes and can not use on a high KV. not for above 1400kv or else it starts strange sounds with bend of speed

These are useable for me, they are paper thin, come bent out of shape and the only thing that was good was they had a twin that you could get counter rotation with your build. Only that cost me more money for something that I couldn't use....

Ran these on a 2822 1450kv 3s 1100mah and they start to bend under their own thrust. Once this happens you loose tons of thrust to power and I just don't trust them with the application I tried them on (FT-F22 Raptor with the motor i mentioned) Maybe these would be better in a lower rpms with less thrust demand that would not bend this prop.

Maybe a multi rotor 1450KV with 2S, that will decrease the rotations by a third of what I was running them at.

My tricopter flies nice and stable with them, perfect for flying fpv with medium fast turning motors. They even resist some crashes.

Bought some sets as they have been kind of expendables on my multirotor acrobatics attempts. Did some minor balancing; work well but break easily when hit by objects; kind of :)

Although these props are a little bit bendy, they seem to work fine. They need a little bit of a balance but the price is right!
