Looks to be about the size of a C-141A, and since it's prop driven it'll be slower than a C-141 was. It'll have better short/rough field capability though over a C-141 but probably not as good as the C-130. The counter rotating props are kinda messed up since you have to supply 2 different drive trains for one aircraft. Would have been easier to make them all turn the same direction, but there is probably a performance reason for them doing it this way.
All in all a decent medium transport that will find a niche in the air transport community.
