It's an honor for us to be the first one in this world to put our hands on this newest Electric RC 3D Helicopter from Art Tech Shenzhen. The Shark 550, is bigger than Genius 500 and flies with even better and more powerful setup. A new frame and cyclic servo mount design makes it easier to install or replace servos, new main rotor head design seems to be an easy conversion to flybarless main rotor head and rest of the things are just sweet. I can't wait to get this bird airborne and see how it will perform out there. Tune in again for more videos coming soon.
