Always thought they were pretty cool. They made a splash in the 1960s and early 1970 and then just faded away. There was an armed version (air to ground rockets, I think), used by a few countries.
I was going to take dual in one, but didn't fit, so flew a 172 instead.
Rick,
Always fascinated with that story. They flew as the MFI-9 MINI COIN aircraft for the Biafran "Air Force" during the Nigerian Civil War.
