    FX-25 vs AX-25

    Bax - When I look at the OS spec's for these two engines I note the FX has more power than the AX. Is this true?
    Thanks, Leo

    RE: FX-25 vs AX-25

    The .25 AX has 0.04Hp less than the .25 FX at their peaks. That's really quite negligible. You'd notice no difference when the either engine's on a model. The .25 AX also turns lower RPM and is ported to turn larger propellers. It will run much more quietly, too.

    Thanks Bax ... that answer is what I was looking. I was trying to decide which of the two I wanted to get. I thought the AX would be the better choice! Again thank you!

    RE: FX-25 vs AX-25

    Hi, I have a new in the box OS Engines .25 AX I will sell with muffler. It has never been run or seen fuel. I bought a plane online and I checked the wrong box and ordered it by mistake. I had it for a while before I noticed what I had done. I will take $100 shipped in US with no fees. I take paypal.

    PS. I should look at the date before I post, I noticed after I posted that this was an old thread. Sorry

    Thank you
