Found this helpful guide to the script that we'll be using https://www.npmjs.com/package/three-vive-controller, the npm stuff can just be disregarded.

On further research I found a better basis for VR Controller here. This will allow for different platforms than just the Vive.

You should now be able to fly in the direction you are looking by holding done the primary controller button (e.g. the trigger on the vive controller).
