Gotta stay up to date, so here's my new entry. Astroliner X Saturn:
At first i was worried about all my previous planes gaining an extra 3 tonnes, but thanks to the new wing's larger size I managed to use less of them. The fuel capacity is the same as the "extended range" variant of the VIII (which I never flew to Laythe), so I had more spare fuel than ever before xD The cargo weights 22 tonnes. I minimized the weight by draining all the monoprop, but apparently I didn't have to. the plane could probably handle at least 25t... === Other than that, this plane isn't particularly good. Tilt tail was a bad idea: when the flaps tilt, the tail bends the other way and counteracts them. So it flies like a pile of poo. I have no idea why anyone would wanna fly this poop, but here's the craft file.
