Feature: 1. Multi Functional: Has equipped with voltage detection, low power return, one button return, 3D self stability, one button inverted flight, GPS hover and other functions. 2. Main Controller: Main controller has 5 PWM outputs and a receiver input port. The PWM output ports are respectively connected with 3 steering engines, the locking tail and the main ESC. The locking tail supports the tail motor and the tail steering engine. 3. Horizontal Positioning: Has built in IMU and barometer to determine the flight attitude and altitude, and achieve horizontal positioning of the aircraft with GPS, so as to achieve flight control. 4. Single Line Modes: Support a variety of receiver types, receiver input support PPM, S. bus and other mainstream single line modes, automatic identification. Uses TYPE C plug, both positive and negative sides available. 5. GPS Module: GPS module contains GPS or GLONASS dual mode receiver and compass, which is used to measure the geomagnetic field and achieve the horizontal positioning of the aircraft together with GPS.
