I've recreated the famous hoverbike made by "colinfurze" (Link to his video: https://www.youtube.com/watch?v=soxxPyaAT1k&t=5s). It's quite tricky to control but looks nice visually atleast.
Controls:
Shift/R.Control -ascend/descend,
Arrow keys - general movement.
F - first person camera.
Have fun :)
