It's called an Immelman and it's a fairly difficult maneuver
to get right. It does involve at least zero g's at the top so
negative oil and fuel systems would be prudent. When I did them in
the Decathlon I would do a very slight push at the top of the loop
and immediately roll, so I never achieved anywhere near negative one
g. The problem in under-powered aircraft is that the roll at the top
is done at very slow speed, requiring a lot of coordinated input to
control the adverse yaw and gyroscopic forces. The other problem was
that when you screwed it up you fell out of the sky in any number of
unusual attitudes. This meant that you should be comfortable with
both upright and inverted spin recovery before you do try an
Immelman. (Or have an instructor along who can recover for you.)
As always I highly recommend basic aerobatic training for
everybody. It teaches you how to fly and it's fun!

I’m really curious why anyone would want to teach themselves advanced aerobatics. Before aerobatics was developed, pilots had to teach themselves because there was no one to teach them. But many of them paid dearly for it. Those that survived the best learned from others who’d succeeded. Isn’t that still a good idea today? Falling out of a maneuver and recovering incorrectly can cause the aircraft structural damage with perhaps catastrophic consequences. That’s the biggest part of learning aerobatics – to learn to recover gracefully, without bending anything.
