Alas I can't take the credit for that aerial footage. I just arranged the shoot and shot the land based footage and then edited it. A mate of mine who operates "blade scenes" did the aerial stuff. He employs a very talented pilot to fly his Trex 700 and operates the camera himself. They have a very similar setup to Copter Kids but recently invested in a Cinestar 8 setup so are now onboard the multicopter bandwagon!
The two man operation allows much more dynamic shots easily I think, but man single rotors are no where near as smooth. Really noticeable after editing my Ecilop footage going to single rotor stuff!
Cheers
