Hah, good stuff. Don't pull a Dolby while you're up there.
This was about 4 summers ago now, RCAF pilot friend of mine has a nice Cit, we did some formation flying with another pilot from Vintage Wings Canada who took some film. Normally he flies the warbirds at his museum, so the Citabria is pretty slow, but still fun for him.
Me attempting to perform a break turn.... :/
I'll post some of the loops later, it's easier to coordinate everything in AH, plus no wind.
