dedgemon said:For reference for the Catto guys. One of my friends is flygin a 9A. He recently took off a Catto 3 blade and went to a Sensenich 2 blade. His impression is that the Catto was smoother but that the Sensenich is quite a bit faster. Don't know what quite a bit is exactly but he paid to do it.![]()
FYI
