I was looking for a payware aircraft that is fun for aerobatics, and fairly realistic, doesn't really have to be specifically for aerobatics, but could be a military jet.

If you want real and military, get the VRS Superbug. You could then fly as any of the Blue Angel Team or a number of other combat aircraft with different paints already installed including CAG's. Give it a try and see what you think. The manual is thick and the learning curve is steep. You Tube will be your best friend until you get a grip on this beast. You can even do Carrier work with this one and with the weapons pack it adds a whole new aspect to combat flying in FSX. Beware it isn't Prepar3d compatible. Cpt. Out.

I would try to pick up something that has realistic flight envelope limits and post-stall maneuvering, makes aerobatic maneuvers easier to learn by the book. My favorite is the Lancair Legacy.

RealAir Decathlon / scout package is AMAZING. It's slow tho
