Update on Dec. 3rd, 2015: Add the V1.01 upgrade to V1.04 manual.The revolutionary flight controllerWith multiple new technologies, Tarot ZYX-M simplifies all complicated operation and brings you easy and natural flight experiences.To upgrade the flight features, ZYX-M is equipped with smart computing and navigation control systems. Pilots can adjust tilt, roll, and pan axis through setup software according to different preferences.Furthermore, it supports fail safe and voice alarm, including range setting and no-fly zone alarm. ZYX-M keeps the multi-copter under control during flights. Main controller:32 bit processorBuilt-in anti-vibration sensorFull metal caseSupports dual S-BUS receiverSupports dual DSM satellite receiverSpecific Interface for TAROT gimbal controlGPS module:Highly efficient GPS receiverHigh gain antennaFast and accurate locatingPMU module:Dual power outputSupports power output to flight controller, gimbal, and video TX in the same timeIntegrated voltage testLow voltage alarmLED indicator:Indicates the multi-copter status in real-timeStandard accessory: USB moduleFeatures:Support 9 kinds of multi-copter. With 3 servo ports for higher compatibilityAccurate speed control under GPS mode:Under GPS flight mode, the flight speed is proportionally equal to joystick movement, and the level speed is proportionally equal to throttle stick movement. Failsafe, one key go-home, IOC(Intelligent Orientation Control), POI(Point of Interest):If the multi-copter lost the signal, it can return to launch and land. When the signal works normally, pilot can pull and switch and activate one key go-home. Smart retractable landing gear:Once activate the feature, the landing gear will automatically extend in emergency case (ex: auto-landing). Pilot can control the landing gear through radio transmitter after flight height exceeds 5 meters. Flight range programmable and no-fly zone protect:Under GPS flight mode, the multi-copter will fly inside the setting range only. Under other flight mode, once the multi-copter fly outside the setting range, the auto return-to-launch will be activated. In places near airport and no-fly zone, the flying height and range are restricted. Prop failsafe (Hex-copter or above)For Hex or above copters, when one of the motor or prop doesn’t work, the multi-copter will fly normally.
