RE: Magnum on par with OS/Saito?
I have Magnum 91 four strokes in four different planes now. I also have an OS 52 four stroke and a Saito 65 four stroke. I think the Saito is the best followed closely by the OS. But the Magnums have performed in excellant fashion and I've never had a bit of a problem with them. I consider myself a sport flyer and don't really look for ultra high performance in an engine..
