Of all the homemade RC Hovercraft floating around out there, this build is not only one of the better looking: it’s also unexpectedly quick. [ScratchBuiltAircraft] sourced foam board from the local dollar store to construct the hovercraft’s body and a heavy-duty garbage bag with a hole cut in the center for the skirt. Air reaches the skirt area from the hovercraft’s EDF (Electric Duct Fan — the big one on the back) which pumps the air through a rectangular hole in the base.
A servo mounted behind the fan controls the rudders, while the rest of the electronics and the battery are cleanly tucked away beneath foam body pieces. We’re not sure what kind of top speed the Turnigy motor provides, but it’s probably impressive assuming it can keep from flipping over. Watch it blast off with a bit too much lift in the video below.
For something a bit slower, there’s always the solar powered hovercraft from earlier this summer.
