The ImmersionRC Vortex is one of my favorite quads.Having been in a hard crash breaking more than half my motors I decided to upgrade to the Cobra 2204 1960Kv motors. They’re really nice, though I’m still trying to feel the difference between these and my old 1306 2300kv motors. Regardless, the performance of the Pro-Tune’d settings in the Vortex makes flying a breeze. Without worrying about PID settings, it’s going to ensure you a good flying expierence.
