Wittman Tailwind
I had one of these, 400 hrs very happy fast cruising, they are the RV of their day
I flew round the UK, France, Spain in mine
Designed by Steve Wittman, air racer from the golden years
I met Steve Wittman in a burger queue at 1993 Reno Air Races who still flew his with his wife at the time.
I moved on to Pitts Specials, but the Tailwind was good preparation as the landing speeds and squirrelly nature are similar.
Pitts driver Skip Stewart has one, running a 3 blade prop, painted the same as his Pitts, it looks fantastic and almost futuristic
Probably it's use is as Wittman intended -a fast support aircraft
