QuadGodGamez That's a part of a system that would make building "planes" more realistic, like Drones++. If you look at mod.txt you might also notice a "torque" ammo type. It was supposed to be like this: you have an engine that acts like a Drone Core and provides wireless power to propellers, ammo to guns & bombs, maybe even control surfaces? With the innovation of 0.14.1 I might still be able to pull this off, but my main priority is making the huge battleship guns everyone is asking for.
