Default 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

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!

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
GFB
