The purchase/exchange is for Government use so money is a factor to a point. I've seen interagency helo exchanges for a few bucks in the past, but that applies only to the UH-60 or similarly colored birds.
It was more of a performance related question. The question I have now is: has anybody ever seen the NATO mounts seen on this pic or anything similar, adapted for the 139?
