WL Toys V686G 5.8 FPV Headless Mode 4ch RC Quadcopter Drone with 2MP Camera w/4GB Memory Card Equipped with a 6 axis gyro the quadcopter has strong stability in flight. One key return function makes it easy to find its way home. Easy to implement various flight movements, stronger wind resistance, easier to control.Adopted 2.4G technology for anti-interference, multiple copters can fly at the same time without interfering with each other. Initialization Steps (Extremely Important Steps Before Every Flight) 1. Insert the battery into your quadcopter, but do not connect it just yet. 2. Place the quadcopter on a flat level surface. It is very important that the surface be level, as a tilted surface will create errors to the initialization of the gyros. 3. Connect the battery with the quadcopter flat on the level surface. Another option is to connect the battery while the quadcopter is being held in your hands, but IMMEDIATELY place the quadcopter on a flat surface after connecting. The quadcopter provides a few seconds after connection before the gyros start to synchronize. Remove your hand and let the quadcopter remain motionless for about ten seconds. This gives the gyro stabilizers time to initialize and set themselves to the level surface. Next step is binding the transmitter to the quadcopter's receiver. After the gyros have initialized, you will now link your transmitter controller with your quadcopter. Turn on the transmitter. Then increase throttle from 0 to full throttle, then back to 0 throttle. You should hear a beep signifying that the transmitter has binded with the quadcopter. This will pair up the transmitter with quadcopter. Now you can use the transmitter to control the quadcopter. Bring the quadcopter to hover a few feet above the ground. With your hand off the cyclic controls, observe for any drifting right or left forward or back. Ignore any drifting that you feel may be caused by the wind. If the quadcopter drifts backwards, repeatedly press the pitch trim button forward until the drifting stops. Repeatedly press the pitch trim backward if the quadcopter drifts forward until the drifting stops.The same process goes for roll control. Repeatedly press the roll trim right if the quadcopter drifts left, and the opposite if it drifts right until satisfied with the hover.
