The World's Fastest Helicopter... AMAZING!
The speed that this Helicopter achieves is an amazing engineering miracle... Not to mention the skill that this Pilot has! I thought trimming my boat for max speed was tricky...

very nice ,,,, "Retreating Blade Stall" has always been the achilles heel in terms of rotor craft top speed ..... The counter rotating lower rotor in this case must be used to to create a higher stall speed for the upper, and the pusher for added thrust .... I't didn't appear to stall though at 300 plus, very cool .........
