Quadcopter is one type of UAV (Unmanned Aerial Vehichel) which has four motors as that rotate to provide lift. UAVs of this type can do a lot of movement in the air while flying among others roll, pitch and yaw. Quadcopter have important hardware are: ardupilot mega fligh control, electric speed control, brushless motor DC, GPS, remote control, batteray Lithium and frame. Quadcopter is also equipped with a camera for monitoring. Quadcopter flying ability is consistent with a large current on the battery used. GPS as a hold position can support the stability of the parameters on the fly quadcopter done mission planner software. The parameters of stability quadcopter flying done by selecting the flight mode. In loiter mode quadcopter flying more stable and easier to control than Stabilize mode. Loiter mode is more stable because it utilizes GPS work as a hold position. As quadcopter security configuration enabled geo fance. Configuration geo fance provides flying height and radius limits movement quadcopter. When quadcopter over the limit altitude and movement radius defined, it will be retraced early quadcopter automatically
