I'm not sure how serious Safe Flight are about mass production, seems a bit concepty at the moment and the below video is a year old, but the quadcopter looks so cool and Star Trek Enterprisey.
Awesome concept, awesome design and what looks to be awesome performance! Time to start I christmas list I reckon
Just put myself down for a Tricopter! Seems like a really good thing to invest in, and I can't wait for that octocopter that's in development
