After walking into my workshop and seeing the spare RC plane parts i knew i had to use them for something. I wanted to be able to use it in my yard, but my yard is very small which excluded a plane. I then thought about a Hovercraft!! I knew that it would only need one EDF because of the ample amount of power one can give out. So i decided to start with a smaller scale model to prove my concept. On the small scale Hovercraft i used a 64mm EDF and it worked perfect! So i decided to build the bigger and faster 75mm EDF with a 4cell 3000mah LIPO battery. That same EDF had previously powered an RC jet that hit speeds of 60 - 70 mph!!
The hovercraft is very agile, fast, and can turn on a dime. It's Possibly one of the fastest RC hovercrafts on Instructables
This Instructable will be more of a guideline to how i built my hovercraft and will hopefully be an inspiration to others to build one of their own.
Step 1: Parts
1x 9gram servo
4cell 3000mah LIPO Battery
Turnigy 9x TX/RX
Dollar Tree foam board
Clear Packing tape
Heavy duty black garbage bag
Rubber Foam with sticky side
Hot glue gun with glue
Step 2: The Base and Mounting the EDF
The base is probably the easiest part in the build of the hovercraft. I decided i did not want a rounded front end so i went with a sharp cut nose. I also painted the base before putting the skirt on to prevent getting paint on the skirt.
The entire body of the Hovercraft is constructed of Dollar Tree foamboard
Motor is a 70mm EDF used on RC jets
60amp ESC also used on RC planes
