The Scout was never designed to be a trainer or a daily means of economical transport. It evolved, outside its sketchy cold war role, as a really useful utility helicopter but not without its limitations.
In the military where costs were not an issue, a conversion would take 40 hours, but before anyone jumps on that, most of the time was taken up with handling exercises. This was ( and is) due to the scouts inclination to bite your backside when you were least expecting it!
The auto comment is a bit misleading as the scout engine off is a spectator sport. Inside its very simple, you come down at 50 kts, flare hard, check harder and expect a long run on! After practice you can explore the boundary but it is a fine line to cock up!!
There are lots of threads about Gazelles in non military hands and the safety issues, the same goes for the Scout. I have nothing to do with the people that sell them but work close by. I am more than prepared to help you make a considered judgement if you are serious about part sharing or whatever.
