I bought few sets in the past but this time the quality wasn't the same, don't know if it was squashed in the box by other items or what but some of them have deformation. still for the price not bad deal (only two pairs were deformed) maybe it'll be snap back to the original form if I fly them, I'll try them after I break all the other pairs lolnice props, they are really bendable, that makes them survive a couple of crashes, which I really like because i have just started flying fpv and crash a lot.they look nice but are very thin and breakable, you get a lot of them but you need them because they break easy. they would be nice if bull nose 5045 or 5x4.5 weren't out there, do yourself a favor and get the bull nose (have tried all 3 brands sold by HK and they all seem to be very close in quality). your quad will fly better, quitter and the props can take a hit without breaking easily.its not like cheap although you bought it in bulk. or i dont calculate well. but they all are look good. i got also green ones in bulk. i will use them in double colors at the same time for front and back on my quadcopter. as always, thank you HK.These are fragile and flimsy props. The other colors are a little less brittle, but black specifically likes to shatter instead of bend. Small branches will take the tip off instead of just putting a dent in it.Great props, great price.Horrible cheap props.
Really, cant find any good reason to recommend these props.
Props are made so cheap, it is not worth it. Props are very thin and flexible. I have purchased the same (brand/size) props from other retailers, they were 3 x stiffer.
With these props do not expect any performance at all. Your flight time will be reduced by half with these props. If you just learning and you know you will be breaking these props left and right, that would be the only possible reason, but even then.. no.
Excellent proppelers, they are very resistant and they are very well balanced, but its better to balance them before flying
