Canadian inventor tests new prototype of record-setting hoverboard. Duru flew up to five metres above a lake for a distance of 275.9 metres aboard his homemade, propeller-powered hoverboard in a trip that lasted more than 1 minutes. Now, Duru is working on a secret, next-generation version of the device. Watch as he takes CBC's Reg Sherren into his workshop, where he is building it, and then to a Quebec lake where he puts the new prototype to the test for the first time.
