RE: OS 46AX - OS61FX
Either there isn't much of a market for hot 2 stroke .60s anymore, or they just don't feel like making them. I'm not sure why though- that would be a great question for engine makers. They've been cramming these 4 strokes down our throats for the last 5 years or so, and don't seem interested in making a screaming 2 stroke .60. Even YS dropped all their 2 stroke airplane engines. I have no idea why they're doing this.
