My third entry for STEAM PUNK CHALLENGE held by @SimpleFlow.

A steampunk style cargo built in the early 40s.

Mk. 3 improved many details outside.

The passenger windows moved backward. Air brake plates was added on the top. Radiators was added to the engines. Rear wing's shape was tweaked. Front wheels brake was entirely removed for safe landing, etc.

Put all above aside, the bigget change that worths a new upload is under the hood. I'm very happy to say that this is my first plane with a detailed cockpit view. Here you have a steering wheel tiller, a throttle control, a brake control and a light indicator. It took me quite long time to test, but it was absolutely worth it.

Also, blade scale and wing deflection degree were tweaked to be less sensitive for a better cargo plane immersion. If you need raw stunt performance. Here's the one for you.
