Hi there. I'm not sure that exactly this GL needs this change. If you want rocket-like experience, you can check out RPG-7 or Railgun scripts. They have more velocity, but i't still can't be called a straight line.

There's something weird with velocity: if you set it too much, like 6000, instead of flying perfectly straight, it starts to deviate from it's trajectory and flies like 20 degrees to the right or left. So I'm afraid of using numbers higher than 2000-3000.
