From a fellow air-tourer dancer
Dear Air Tourer, you (and you, too, Agaricus bisporus, just as well) describe the same technique that I laboured to develop to achieve a positive-G manoeuvre in a 100 hp Victa, that you could put your dear ol' mum through (done) with her eyes shut, but then the second time ask her to now open her eyes 'at the top.' Frabjous fun, if you have the right mum/friend/victim. Otherwise hysteria results. Pick your 'victim' carefully.
The trick is not to achieve one-G. It is really to manage energy/ flight-path to achieve 'never-negative-G'. (Simple engines keep running then.)
This whole discussion really boils down to how much energy your aeronautical device has, how much drag, how much (sic) wing loading, how much (sic) velocity, roll rate, aileron drag, etc etc.
Our discussion's we-*can-vary-the-rifle-bore military grunters can essentially point and do, as can our (magically)-excessively-powered competition aero-comp friends. Vertical hover, anyone?
We lower-order growths have to do with making the best of what we have, and what we have/had determines how you carve that bit of air, and whether you do it for your own bottom's pleasure, or for an audiences’.
Self taught (Aerobatics? Now? Dear, you've just gone solo!) much later I was having doubts about my BRs, and asked B.T. (and ancient tiggy-moth displayer of note) to help me out (my only aerobatics instruction ever: shock) and he finished up throwing his hands in the air (litterally) & giving up (on the Victa).
Yet he could carve the most exquisite aeros in a Tiger. But that was another technique altogether.
As me dear old (still firing) mum would say, "Whatever takes your fancy, said old Mother Clancy, as she kissed the cow."
Good Lord!
That's disgusting. I thought *we* invented that sort of thing. . . .
Barrel rolls, you awful minded person you. Barrel rolls.
