What do you do when you have a whole warehouse sized facility and an industrial sized CNC foam cutter? Clearly, the only choice is to build giant RC aircraft, and that’s exactly what the folks at [FliteTest] teamed up with the illustrious [Peter Sripol] to accomplish. Did it work? Yes. Did it work well? We’ll let you be the judge after taking a gander at the video below the break.
[Peter Sripol], known for building manned ultralight electric aircraft from foam, was roped in as the designer of the aircraft. A very light EPS foam is used to cut out the flying surfaces, while a denser green foam board is sourced from the local home building store to construct the fuselage.
The build is anything but ordinary, and kids are involved in the construction, although the video doesn’t elaborate on it very much. You can see evidence of their excitement in the graffiti on the wings and fuselage- surely a huge success on that front! As for flying? Four large motors provide locomotion, and it’s barely enough to keep the beast flying. A mishap with the Center of Gravity demands a last minute design change which renders the rudder almost useless. But, it does fly, and it is a great step toward the next iteration. Just like every good hack!
