I certainly don’t doubt one could get killed by an RC helicopter. It’s the specific method in the headline I take umbrage with, lopping the head involves cutting through a lot of skull, not just the initial impact point. A lot of factors, mostly revolving around weight, make that highly unlikely. Cutting through soft tissue I believe, breaking bones even. But not top lopping.
Those things are killer Dragon Flies, like in the Tribulation.
My idea of flying an RC helo was walking along side one that is sedately hovering.
