The head on the Goblin 380 does come preassembled, but you MUST take it apart, clean all of the oil off of it and thread lock everything in place. If you are running high head speed or flying 3D, you will want to put the shims in the head which are NOT installed but are included.

In this video, I will show you how to completely take the head apart, clean everything up, thread lock everything and finally get the head mounted to the main shaft and install the top plate assembly into the frame.
