This is propellers the worst quality what I've ever seen. All is very bad, uneven, many deburring plastic, not all the O-rings. Guys from HobbyKing if we read my message please delete this is product from your price list, to other buyers do not make such mistakes as I.

I got these today. There was lot of loose plastic around. I trim these to look nice. I balanced properly. And these fly like sh**, really these DO NO WORK. I almost flipped my quad. It was only pure luck that i avoided chrash with moped.

I want my time back... and money!

Was not happy when I pulled these out of their pack. There was flashing still attached to the props. Once I put them on and spun up my quad, I could see that there was a considerable amount of vibration on one of the props.

Not helpful.

These are rubbish as everyone says. no more balancing needed than any other prop but provide no thrust. Quad copter required about 20pcnt more throttle to hover compared to different props of same size.
