You said it. My all time best pattern plane was a Vertigo II. I didn't build it. Bought it complete with Kraft retracts from Joe, a KC-135 Air Force Pilot who was stationed at Carswell AFB in Ft. Worth at the time. The plane weighed nearly 10 pounds. With a Webra Speed .61 pulling it, the performance was OK but not great. Steve Helms told me to get a Rossi with a pipe and I did. That engine made a huge difference for the better. It was just a different airplane with the Rossi and a Zinger 11X7 1/2 prop. We clocked it on Highway Patrol radar at 135. The Vertigo excelled at aileron rolls, slow rolls, and point rolls. If I had a Vertigo today, I would putt a Jett 90L and Jett muffler on it. With that power, verticals would be spectacular. Here's hoping your Vertigos give you many great hours of enjoyment.

PS- I flew more than 100 gallons thru that great old airplane.
