Japanese tandem twin-rotor synchrocopter
Okay, I know nothing about this. The link to this video by Japan's INA Invention School (www.ina-hatsumei.com) was posted by amsci99 on www.secretprojects.co.uk. The thing is called the Sky-Crane 2. Basically it looks like two Kaman K-Max intermeshing-rotor helicopters glued together. If you know any more about it, let me know!
