The ones I've done are on about 60 deg upline, then left knife edge, and
then full forward stick, right aileron, and full left rudder. It'll go
around and do three tumbles, each at right angles. It usually ends in a
level attitude at right angles to the original line of flight, with the prop
howling at full RPM, and zero indicated airspeed. It's actually not violent
at all, with little g load.

When I first got the Extra, now seven years ago, I promised my wife that I
would never do airshows, and never charge anyone for a ride (not that I
would anyway). It's been a great ride and lots of fun.
