Beware the adapters are 3mm not 4mm! With that being said I needed 3mm anyways so a win win situation for me! I'm using them on a custom Blade 230S.

Value to the extreme. I think it will be almost unbreakable when I consider that it is mounted on a 4mm aluminium alloy shaft. I bought a couple of sets and HK threw in an extra pair. Cheers to them. I don't know how they manage to lay them up but they are solid, symmetrical and well balanced as they come from HK. I am new to drones but I have chosen these props for the Viking 1308 4000kv motors I also purchased from HK. I ran a few simulations on e'calc and discovered that these motors with these 4028 cf props will spin at more than 36000rpm and lift a 450g quad at a rate of 16m/s and when pitched for full speed my quad should outrun and angry dog at 80+km/h. Personally I don't believe the calculator, but I am very impressed with the motors and these robust props.
