Dear Bradenav
The only ''jet'' version I know of is the AM-12P which was evaluated by the Italian AF. It was a modification of the AM-12 (Praga D piston engine) with a Turboméca Palas and first flew in 1962.
And..... to make things easier, I have a small photo photo of what is described as the AM-10, but with a single fin and not like LV-X7 with twin fins.
I though the goal of PPRUNE was to solve problems, not to make them bigger.
I suggest we limit ourselves to the worldwide fleet of AN-225s.
