I've had a look at the family model, actually like the looks. My issue with the ease statement is that according to data that was a pre-production model concerning me whether all mission essential equipment was accommodated as it was likely a demonstrator only. Same concern as to whether modern kit could easily be accommodated minus a major structural modification that takes it out of the realm of cheap and quick. As to the jigs, I have no clue, but have to factor in this is an aircraft that went out of production a number of decades ago.
Now we both know that if you write a big enough check, it could be fitted with two seats, but at what cost with regards to capabilities?
