At the 3D Master there was a lot of demo flight from different vendors, but one of the most chocking this year was the two Three Dee, Henseleit Helicopters doing a mid air collision, as i wrote in my previous post one was hovering or flying slow and the other was flying full speed into the other helicopter. Resulting in a ground impact 200 meters down the flight line and it was cached by the safety net.
