Here is a hybrid drone that can dry across difficult terrain and fly to reach areas not possible with regular quadcopters. The X-TANKCOPTER comes with iOS/Android app control. It has a 120-degree wide-angle 720p camera to capture all the action. A virtual reality (FPV) mode is also available.
The X-TANKCOPTER is capable of driving, climbing, drifting, and flying. It has propellers that shut down once they collide with an obstacle to minimize damage. Expected to ship in June.
