Micro R/C hovercraft with single propeller. This was made from the wreckage of a ultra-micro 2S R/C airplane. It uses foam for the skirt material so it can only be run on a smooth surface.

NOTE: Not kid or pet friendly with exposed propeller.

Maximum time at full throttle time in this video was about .1 seconds. This thing is very fast. Run time is around 6 minutes.
