It has been fifty years since I made my first few laps inverted. I still remember it very vividly. I could take you to within 10 foot of where I was standing on the baseball field. I think I was on my third Veco Tomahawk. $ 3.50 each.
Someone is always tickling the old remember it buttons around here. I'd halfway forgotten my first two Tomahawks, that also predated skillfull inverted flight. Two of those ended up combind into just one, but not before another oldie of mine, a Circus King, was what I was using the day someone pointed out that lazy eights were filled with "turns AWAY from the ground", and were ideal to stretch longer into full laps of inverted flight.
I was doing my inverted a really hard way, with half of an outside for an entry, likely because that was more similar to a reverse wingover midway point, but with slightly less speed build-up quite so close to the ground. two years, plus or minus, later, I was doing the 1955/56 pattern (not well, but most of the maneuvers were recognizable).
