Sonny recently shared his current progress of his UAV Quad Copter project and included a test flight video.

So today I had my first real flights with my quadcopter UAV.   The setup is pretty advanced and it takes a lot to get up to speed.  I’ve learned a lot from my build.  I made custom printed PLA motor mounts, which have worked out really well to hold them on the end of aluminum pipes.  Unfortunately the cross in the middle which is also PLA could not handle the rough landings and cracked.  I’ve secured it for the time being, but I think I’ll be milling something better Wednesday.  If I can work out the stability issues, I’ll bring it Friday.  Anyway, check out the first flight/set of flights.
