Clockwork is a sophisticated Minecraft mod that combines the machinery of Create with the physics and moving blocks of Valkyrien Skies.
Want to build a plane? No problem!
We have wings, flaps, and propellers, all with real lift, drag, and propeller physics.
How about an airship? Not an issue!
The hot-air balloon burner has you covered.
What about bearings?
The Physics Bearing has all the goodness of a regular Create bearing, but blocks remain functional while moving, and the bearing has momentum.
You can even make a car! Yea those wheels are probably not round enough :p
