@System1024 Well, how well does it fly or what makes it fly? It is among the most stable planes in ME, so I'd say it flies very well; what makes it fly is that Peaceman's rudders have aerodynamic properties, and when they are pulled through the air with the use of the propeller, it forces the plane to fly. To control it, you need to press F on the controllable drums and set up your keybindings for them.

Industrial engineers!
Too bad keen's doing f-all for medieval engineers and is just milking SE for DLC monies

Anyways, how does this plane fly?

We need a Steampunk Engineers for all these trains and planes. There's a game pitch in the Keen support forum worth reading.
