I know what you mean about Aeronef. They’re a bit of fun, but in the end there was never enough going on to suit me. I like a bit more crunch.
Did you play Sky Galleons of Mars or just the Space 1889 RPG? I really like Sky Galleons and have been contemplating working up stats for my Aeronefs. I just wish I had some Martian screw galleys and kites in the same scale.
