If you want a kit..... Patriot .40 all the way for the YS45. (just like everyone else said
Nice jet looks.....can be dolled up a bit to look like an F-4, A-4, F-16 or even an F-86. Check back on some past patriot threads. Some good photos in there. aircraft performs well off of grass or hard surface.
If you can find an old Direct Connection Tiger Shark F-20 (.40 size kit) on ebay or somewhere.... that is an execllent aircraft too... just been out of production for a while. Hard to find.
