I'm guessing that's a .40 size plane? I have that engine and while it's reliable, it doesn't make the horsepower that a comparable Saito or OS does. I'd say its comparable to a bushing .40, but of course turning a bigger prop with less RPM. If you plan to putt around scalelike and don't intend to pull vertical uplines more than about 20 feet, the .52 Magnum will be fine. But if you want to fly the plane like one would expect an airshow performer to do, go up to a .60-.70 4 stroke.
