Andy Ks nonsense about the Puch being "aerobatic" is a giggle. Red Bull
flew Blaniks, not Puchacz and now they can't fly Blaniks, they sure
haven't switched to Puchacz.

Red Bull still operates the Blanix Team using Blaniks. They iniatiated the
STC that made this possible.

PS: Puchacz is certified aerobatic in quite some countries. Low Vne, but
other than that it is quite capable of them too. I speak from experience.
