There a bit of a legendary machine the old 12E. Better performance than the 47, they were used a lot in New Zealand for Ag work, as well as chasing deer, until the 500 came along.
My first ride in a helicopter was in a Hiller 12E over Frankton Heights, Queenstown NZ. The pilot was my fathers cousin, Graeme Allen, who worked for Alpine Helicopters. I was 13. Along time ago now.
