Congratulations!
Whatever you do, when learning inverted, keep your handle vertical. Bad habit, hard to break, to tip it horizontal (as many do).
First time I tried inverted, I was about 16-17, flying my first and only Ringmaster S-1 with an early Veco .29. Crashed, I did. Next time I tried, maybe two years later, was with a combat model (they were all "Fast" in them days...about 100 in this case). I told myself simply that the next input I would give would be "down". I have crashed since, but not while flying inverted.
When I came back to flying CL in the late '90's, I sometimes checked my total flight time by looking at my stopwatch while flying inverted, but decided that probably wasn't a good idea. Learning the pattern and getting the flight time under 8 minutes stops the need for doing that stuff anyway.
