I made a RC hovercraft this morning. This is something I’ve been meaning to do for about 20 years.
It took about an hour.
It’s a green foam tray (free on request from the produce department at the supermarket) with a hole in it, a cut-off plastic cup, a ducted fan/motor from eBay, battery, and RC receiver. And a lot of hot glue.
The bolt and washer are to balance the battery – they’re hot-glued down.
Here it is running. It’s way overpowered – it works best with the throttle at about 5%.
Later I made a skirt out of tape – no pics; it looks about the same, just flies higher by the width of the tape.
I’m glad I got that out of my system – now I can move on to something else.
