This mod is a combination of Planes, Vehicles and WW2Guns rewritten with a whole load of awesome new features and designed to allow easy custom content creation by anyone. Flan’s mod alone is useless, it requires content packs in order to be of any use.
Recipes:

Most actual items and blocks are separate from the mod, distributed in content packs, but there are still a few things you will need to know how to craft that are in the base mod.
