I love the Saito .91 in mine, and I've never been one to say something has too much power, but I could go vert all day and never use over 1/2 throttle. Most of the time I'm just a few clicks above idle. I'm gonna do an experiment next time I get out to the field. I'm gonna pull it into a hover, then count the clicks above idle I am. When I get back on the ground, I'm gonna tach the engine at that throttle level and see what RPM it takes to hover it.
