Dora-9,
There were several JP aerobatic teams in the late 60s, but I don't think I ever saw more than a four-ship.
PS I've always had a great deal of respect for pilots flying formation aerobatics in low-powered aircraft, doubly so since I put a couple of hours on a Vampire T11 a few years ago, which is a positive rocket-ship (another 1000 lb of thrust, but admittedly heavier) compared to a Tutor or JP 4.
