Finished this COIN aircraft. I'm quite pleased with it, generally.
Writeup still to come. It can carry somewhere around 24 passengers/12 stretchers/a lot of cargo, and is armed with a rotary 20mm cannon under the nose. Can be equipped with door/ramp-mounted guns and has 10 hardpoints - two on the tips of the lower wings, six underneath them, and two underneath the fuselage. The engines are in the fuselages and there are larger intakes on the interior side.
This is somewhat of an experiment in shading, too.
