Another possibility, to help control costs, would be to consider a 7ECA, same basic airframe as the 7KCAB but with less horsepower, (and fuel burn). I owned an early (1964) 7ECA which was powered by a Continental O-200 and it was a great combination aircraft. Later aircraft use the 115 hp Lycoming which are preferred by some. Doesn't have the vertical or inverted performance of the 7KCAB but still a lot more fun than a C-150; just seems like aerobatics should be flown sitting on the center line of aircraft with a control stick in your right hand and the throttle on your left.
