RE: OS 46AX - OS61FX
I don't think you'd ever see 2 strokes completely disappear- they can't make a dirt cheap bushing 4 stroke aimed at the beginners as with 2 strokes. But what seems to have happened is the fire breathing, pumped 2 stroke powerhouses have given way to four strokes. I wonder if this has more to do with lowering noise output, fear of losing fields, and 3D.
