I'm thinking of doing some relatively basic aerobatics in my 360,
basically loops, barrel rolls, and anything else with continuous
positive G.

The area where I'm a little hazy is any maneuver with brief moments of
zero or even -1G.  Are these to be COMPLETELY avoided, or is it ok for
very brief stints.  I'm concerned about the prop and engine.  My
knowledge of the internals of the engine are weak, but from the little
I know, without an inverted oil system, prolonged inverted flight
isn't an option.  My question is, is 0 to -1G acceptable for 1-2
seconds?   I'm thinking here of aileron rolls, or cuban eights.

I don't have my heart set on doing those, per se, but just want to
know where it would be smart to draw the line. I know the airframe can
handle all of that, and then some, it's a question of the engine and
prop.

Thanks for any advice.
