these are the straightest props i have ever had.& i have had at least 10 different types here!0 vibrations,very strong & not flexible. if you have to bore out the hole to 8mm,the way its designed you will not take anything off the hub leaving it 100pcnt solid! great!

Bought 4 lots of these giving me a full set of spares for my quadcopter. Not had any issues with hole being off centre and are very well balanced. Would definitely recommend!
