Ask Dudley for technique, but as for the physics: a perfect loop would
have a constant acceleration.

Only in zero G.

Just take an accelerometer with you and
see how consistent you are (preferably one that can discount the Earth's
gravity,

Are there such beasts? I know it's theoretically possible, but it would
be very hard (and expensive) to build such a gadget. Do they really
exist?

Yes. The Naval Test Pilot School uses extremely sensitive accelerometers
on the T38's used for coupling and departure research flights.

It's not so much that they have to be sensitive as that they would have
to incorporate an AHRS (or something equivalent) in order to figure out
which way is down.

And what is a coupling and departure research flight? And why would you
need an accelerometer that compensated for gravity to conduct one?

No offense intended, but I think I've had just about all of this thread
I can handle for one day. Please ask someone else.

My offer stands as stated to you personally. If you have something to
say aviation wise, comment, statement, or question, I'll deal with it
just as I would anyone else here; with a respectful and non hostile answer.

Fine. But would you not extend the same offer to Ron. He seems to have a
very interesting question.

have a constant acceleration.

Only in zero G.

And only if speed is constant.

Cheers

It's very simple to do this. Simply incline the loop 90 degrees from
the axis you were thinking of. This has another name - a 360 degree
turn. ;-)
