I fly a Pizazz with a Saito .72, and while it has a fair amount of power, it is not as light an airplane as I had hoped, and it really needs a bit more. I thought of dropping a 2 cycle .61 in it since I don;t own any other FS engines, but it really needs either a Saito .82 or better yet, a .91 FS to make it scoot (vertically). The .72 will hover it, but it does not have a lot of excess to climb out.
I use coupled flaps and elevator, as well as ailevator, and it's a lot of fun to horse it around. I launch underhand (when grass too long) at about 45 degrees elevation, no sweat. Vertically, uh no, not without more HP.
Hey, this isn't Extreme Speed talk!!! Well okay, how about roll rate? Does that count? Or, I'm practicing to hover my Whiplash? Yeah that's it..
