Just saw a new OS engine  - OS 95 AX !
though $50 more than the 91FX, seems to have the qualities of the AX series .
Slightly lighter than the 91FX and more power too !
If anyone gets it, do post pictures and  a review here.

And do not forget cheapear for OS to manufacture too, where the older design with true chrome liner plating have been replaced with cheaper Nickel plating which is much less harder than chrome and also reduces cost of production. Even though the quality has been reduced the same is being touted as ABL liner  (Advanced Bimetalic Liner) as if the previous ABC liners were single metal.
