Said the salesman.... the tail is straight. Must be your Astigmatism.
I want an Aerobat also, but they are hard to find. Two years ago I passed on a '75 A150M, which was "asking $35K" at the time I was returning to flying after 8 years..and did not realize the huge jump in prices. This one was "near perfect, low time".. however a standard C150 in similar condition is a whole lot less..no "Aerobat" premium. That said. I used to fly Brian's plane long before he luckily bought it. Never did aerobatics, and likely I would not today. Thus, I got a really clean C150K with low time for about $18K. No regrets.
Just the point being...are you "really" going to do aerobatics, or is it just like me.. "I want one".
