Hi. I am a developer of Kinetic Weaponry using Vanilla blocks in SE. They often work best with a Speed mod, but the Coilguns I develop are devastating to any ship when they are hit by the slug. I am also working on a Corvette type ship, and current tests have shown that it is a very fast vessel. It is quite large, but it is extremely fast. And it looks fast as well, and that is pretty hard to do in SE.
