Take full control of your Spark quadcopter with the Remote Controller from DJI. The Remote Controller features an enhanced, dual-band Wi-Fi signal transmission system that allows it to communicate with the Spark from up to 1.2 miles away. When using the Spark in Sport Mode, the Remote Controller allows you to fly it at speeds of up to 31 mph. You can also connect the controller to your compatible smartphone, enabling you to watch a live feed from the Spark's onboard camera on your mobile device.
