Made by Andrew Gotow, a small and nice pdf tutorial complete with scripts,model,textures and Unity scene file.
Eventhough he is using Java, the tutorial brings up some interesting topics such as creating your HUD, particles for weapons, colliders and more.
If interested you can find it at the Unity forums: http://forum.unity3d.com/threads/414...opter-Tutorial
