It is the dream for millions of sci-fi fans - a working hoverbike.
Now, a British inventor has revealed a fully working version you can buy.
However, there is one slight snag - it's only the third the size of the real thing.
The firm says it producing a 1/3 sized version of its design to help fund the full sized prototype.
'This drone was originally built as a proof of concept for our latest full-sized Hoverbike prototype,' said Chris Malloy, the drone's inventor.
'After testing the 1/3rd Hoverbike, we realized that it had lots of features that made it a fantastic drone, not only this - selling this scale Hoverbike to the public would allow us to raise funds to continue the development of the manned version.
'The objective of this campaign is to kick-start sales of our beautiful 1/3rd scale Hoverbike drone and accessories via your pledges, and to help create a long term income stream that we can use to continue development of the manned Hoverbike,' it says.
The full sized design uses a motorcycle engine and controls.
However, the smaller version uses electric motors, and can be controlled using a standard RC helicopter controller.
