The UDI U818A HD has the Headless/IOC function. Usually, the forward direction of a flying multi-rotor is the same as the nose direction. By using Headless/IOC, the forward direction has nothing to do with nose direction. This lessens the steepness of the learning curve and allows the pilot to enjoy flight while slowly learning each specific orientation of the quadcopter.
