I'm with you wings, and I'm a Magnum convert from OS. I used OS for years because of their reliable performance and of course the name. I moved to Magnum about a year ago, and now have four, all four strokes, and wouldn't have anything else. I figure they improved the OS carburettor, and my Magnums start better than the OS, and I never have any trouble with any of them. No deadsticks either.

I don't see much, if any, difference in operating a 2 stroke or 4 stroke. After all they both use a glow starter, both have a carburettor and needle etc. If you open them up they're more complicated, but I don't find tuning any different. I wouldn't go back to 2 stroke; 4 strokes use a lot less fuel and have a realistic engine sound. Sure they cost more but the gap is narrowing.

I was out flying this morning and had about six flights with a newie, an Extra 330S, 63" span running a Magnum .91 FS. Great combination.
