With parts that could have been used to build a remote control jet, ScratchBuiltAircraft on Instructables managed to make something even cooler: a remote-controlled hovercraft.

The body of the hovercraft is made of foam board, while the plastic ‘skirt’ around the bottom is just a simple heavy-duty garbage bag. Where the build gets really interesting is in the electronics. The thrust for the hovercraft is provided by an electric ducted fan powered by a LiPo battery. This fan also pushes air into the skirt of the hovercraft thanks to a duct located directly behind the fan.

Noah Shactman just brought Israeli defense contractor Urban Aeronautics’ AirMule VTOL UAV project to my attention. The photo released by Urban Aeronautics, shown above, purports to show the first successful hovering flight of an AirMule prototype, secured against wandering off by guy-wires. Video would’ve been more persuasive. The design goal of the AirMule project is to produce an unmanned vehicle that can be used to ferry supplies into, or wounder soldiers out of, a hostile, closely-packed urban combat environment.
