that's it. just go with the flow. If after a while you start drooling over the p51, by all means fly it. if it is aerobatics you crave, anything that is mid or low wing wth large control surfaces and is way overpowered is usually an aerobat. you don't have to go warbirds only or pylon racing only as i know some people do. just make sure that before you buy or fly the plane, you know it is the plane you want.
