You wouldn't have guessed it: To do simple erect spins.

I am aware that some pilots claim to have been able to spin the 21
without the tail ballast. I'm not among them.


Technique that has worked for me in just about every 21 or 103 I've
tried it (and I weigh 95 kg or so):

Establish a stable slip, nose slightly higher than normal, for purposes
of this discussion, left wing down. Apply full left rudder, at same
time move stick fully right and back. No need to jerk the controls,
quick smooth movements are all that is needed. You might have to play
with the slip angle a bit...
