I originally purchased a Sensenich and did all my taxi tests with it, but decided to buy a Catto due to the ground clearance fears I had with the Sensenich. I flew the Catto all thru my phase I testing and it performed flawlessly. I can't compare it to another flying prop as it is the only one I've flown, but I can say that the experience dealing with Craig Catto was good. It took awhile to get the prop, but it is well built and looks beautiful.
