Aerobatics and your plain old C150

If a picture is worth 1000 words, a video is worth a million!

Every pilot ought to be able to do that, IMHO.

PS  The altitude gain during a wingover is up to you.  The
more altitude you gain at the apogee, the slower the airspeed
will be.

Also, the rate of bank change - and the maximum bank -
are similarly up to you.  There are no "right answers" and a
lot depends upon your initial energy which is your airspeed.

Note at the beginning of the video, the IP trades off a little
altitude for airspeed.  Pigs and sausages, I say.

All you can really say for sure about a wingover is that your

- entry and exit altitudes are the same,
- altitude is gained and airspeed lost during the first 90 of heading change,
- it is symmetrical,
- the ball is in the center, and
- you exit with a heading change of 180.

Bonus points for doing it inverted - an "outside" wingover  ^-^
