How close to the ground can a vehicle go and still count as flying? FliteTest, the group of drone crafters and model airplane enthusiasts best known for their giant Star Destroyer and Helicarrier craft projects, this week set their sights much, much lower. So low their vehicle isn’t a plane, but a hovercraft.
Well, one hoverboard, and one weird low flying machine:
Both craft were home-built using hobby kit motors, power supplies, and controls. The FliteTest team built them over a course of the day, partly for fun, and partly to showcase a water-resistant foamboard.
