Fantastic propellers, well balanced at stock.

A little overweight but strong, ballanced, no flexibility.

Seems to be very efficient and gives good flight times. No in flight failures. These blades run very smooth.

Great props, they were able to handle most crashes I had, but they aren't balanced. I was able to balance them using hot glue for the hub and sandpaper for the blades.

What a prop! Very strong and finally a prop that will work on my bumblebee 550 quad on stock motors! The hub is big enough to be drilled out to 9mm and only required little balancing. Will buy a spare set in case i need them but they are really nice tough props!

Sorry Guys, they're at a good price, but they're not worth the money. Like other posts have mentioned, they have issues with the hub not being in the center line with the blades. If you look down the prop you can see that the blades favor one side. I added weight to the same side of both blades just to see what it would take to actually balance them, and the drastic amount of correction needed to put them into balance renders the props unsafe and unusable.

So far all of these props that I have used come well balanced. They are rigid and durable props. Many have survived several crashes attached to quads and have lived to fly again

These props are amoung the worst props I have ever bought from HK. Don't try to balance these because it is just waist of time. They all have hub problem so it is beyound a simple
balancing.

I purchased these and the 10x4.5 versions and all of them have a vibration issue. After many attempts at balancing them I found that the hubs were not centered. Thus causing the rotor to be Out-of-Round. Unless you are prepared to fill and drill new, centered holes to fit your motor shafts, then stay away from these. I was able to put the smallest hub inserts in and re-drill them to work for me but this is not ideal.

Very disappointed with these props. Just like in the previous review by Skorpen2, I cannot use these props because they are totally off balance. I put a giant blob of hot glue and they are still unbalanced. I tried them on my hexacopter, and the blob of glue just flew off because it was so big and heavy. I can't use them at all
