A hovercraft that uses 55 mm fans to hover and move around. It is controlled by a standard R/C controller.

Here is the link to the original version that I looked at for reference. My main dimensions are 21.33 cm wide and 42.66 cm long.
The first challenge was that I had to make the connections more permanent so that they would stay connected on their own. For the fan-ESC connections, I just soldered on banana plugs and covered them in heat shrink to provide easily disconnectable connections. The battery-ESC connections were tougher because the batteries have special connectors attached to them called XT60 connectors and the ESCs do not. I overcame this by buying some connectors of the same type and soldering them on to the ESC wires. I also covered these in heat shrink. Another major challenge was weight distribution. If one side of the hovercraft is heavier than another, the hovercraft will drift off without any inputs being pressed. To overcome this I made the batteries and most of the rest of the electronics symmetrical because the batteries are the heaviest parts. The last major challenge with this milestone was attaching the thrust fan to the servo in the back. It needed to be secure and also balanced, so I decided to use hot glue to attach it. Here are my bill of materials, build plan, and PDF version of the STL file. The STL file can be downloaded below.
