Fred, get an aerobatic rating and find someone that will teach you to fly a Pitts. If you haven't flown one already, you will enjoy it so much that you will find the cash from somewhere to continue doing so.
Yes, it costs money, but anything that is as much fun as this costs! It will make flying a-b a thing of the past for ya! The aerobatic bug hit me so hard back in '04 when I first got authorised by my instructor to practice loops and rolls in the 2160 myself that I worked 50hrs a week earning $10/hr (massive money at the time
) to pay for an hours worth each week for nearly a year.
