RE: Which OS For My Patriot?
If you either own or are choosing between the two engines, go with the OS50. It respond much better to a pipe than the AX does. The 50 is a very good engine.
just for info....every so often you can pick up a Jett .46 off of the Hangar Sale clearence list for somewhere around $215. Comes with the tuned muffler... full warranty. No tuning....just break it in a bit, put a 9x8 up front, and enjoy the Patriot. You can request the current list off of the website. List changes about daily.
