Ordered these for several 250 quad and 300 hexacopters. These have no flexing like the plastic version. Carbon is strong, but will shatter when hitting something hard like walls and trees. Not recommended in the test phase of your craft. Safety first, so make sure these props do not touch any part of your body when spinning! You will regret it the moment this happens ...

I have tested these carbon propeller on my 250 quadcopter. The 3 blades at the carbon propeller are not good in balance. It is necessary to bring these 3 blades in balance. i have the backside of this blade with something more weight with abrasive paper sanded.( look at my pictures ) When the propeller is in good balance, he works good, but he has something more weight as the plastic propeller.
