Product description The A2 Flight Control System for Multi-Rotor Aircraft from DJI provides the autonomy that four, six, and eight rotor aircraft require for stable flight. The A2 breaks down into five main components: the MC (main controller) with CAN-Bus hub and receiver, IMU, GPS, PMU, and LED. The IMU, GPS, and PMU provides the MC with altitude, acceleration, location, orientation, and other data which gets combined with any pilot instructions and translated into motor response. The system supports Quad I, Quad X, Hex I, Hex V, Hex Y, Hex IY, Oct X, Oct I, and Oct V motor mixes. The included receiver is compatible with Futaba FASST series and DJI DESST series transmitters. A2 Flight Control System -
The A2 flight control system is comprised of the main controller, IMU, GPS, PMU, and Bluetooth LED indicator
Main Controller
The aircraft's equivalent of a CPU. The main controller takes pilot input and, factoring in data from the IMU, GPU, and other sources, instructs the ESCs at the motors. In addition, the A2 main controller incorporates a 2.4 GHz DR16 receiver which is compatible with Futaba FASST series and DJI DESST series transmitters (radio controllers). To connect peripherals, the main unit features a CAN-bus terminal with 12 output channels
IMU
The IMU, or inertial measurement unit, is the primary source of information used by the flight controller so that the aircraft can maintain a stable flying condition. It uses a combination of accelerometers and gyros to collect this data
GPS
The GPS allows the aircraft to keep track of where it is in two-dimensional flight. This enables various types of assisted flying not otherwise possible, such as keeping the aircraft in a fixed hover while shooting video. A high gain antenna mounts on the end of a stock installed on top of the frame
PMU
The power management unit (PMU) regulates power being fed to the flight controller and other components. It features voltage detection and alarming, and has an extendable CAN-bus port
LED Bluetooth Indicator
The LED-BTU-I module provides the USB and Bluetooth connectivity required so you can adjust various flight control parameters using a computer or mobile device. Bluetooth wireless communications can be extend using the 2.4G Bluetooth Datalink, which relays Bluetooth data over 2.4 GHz Wi-Fi for use with the iPad Ground Station, a waypoint-based autopilot mapping system - Intelligent Orientation Control (IOC)
- On multi-rotor aircraft-- as with airplanes--pressing "forward" on the transmitter (radio controller) moves the nose forward. However, because multi-rotors are largely symmetrical, it can be easy to lose track of which way the nose is pointing, causing the controls to become counter-intuitive. To avoid this, IOC--when enabled using the assistant software--defines movement relative to the pilot so that, for example, pressing forward will always result in the aircraft moving forward from the pilot's perspective
- Point of Interest (POI)
- When the GPS signal is good, users can record the current position of the aircraft as a point of interest by a preset switch on the transmitter (radio controller). The aircraft can achieve a circling flight around the point of interest with the nose pointing at the POI in an area of 16.4 to 1,640' radius, when the roll command is given. This function is ideal for shooting of a fixed or stationary object, creating an aerial tracking shot
- Intelligent Landing Gear Function
- Once you enable the Intelligent Landing Gear function in the assistant software, the landing gear will default at the lower position when the aircraft is on the ground. The system will also lower the landing gear in an emergency, the event of motor failure, or on auto landing, to protect the aircraft and gimbal. You can lower or retract the landing gear using a switch when the aircraft's altitude is over 16.4' from the ground
- Return to Home Failsafe
- Assuming the GPS has been properly calibrated and enough satellites are available, the aircraft will automatically return to its home point in the event contact with the transmitter (radio controller) is ever lost
It is also possible to assign a button using the assistant software that, when pressed, will cause the aircraft to automatically return to the home point - One-Motor Fail Protection
- Available when the aircraft is in attitude or GPS attitude mode. In the event one motor fails the aircraft can maintain a stable flying condition, enough that it can safely be brought back home and landed
