... statt Spekulationen hier mal die offiziellen Spezifikationen:

MULTI-ROTOR STABILIZATION CONTROLLER

DJI A2 Multi-Rotor stabilization controller is a complete flight system for various multi-rotor platforms for commercial and industrial AP applications. Based on the technology and design philosophy of DJI’s Ace series of high-performance controller, the A2 offers you a brand new flight experience. Its flight mode setup provides a seamless transition for current Ace One AP professionals. It utilizes high quality components precisely calibrated with temperature compensation in all gyros and sensors, industry renowned flight algorithm in autopilot and UAV field.

Built-in 2.4g DESST Receiver and JR/SPEKTRUM Supported

The A2 has a built-in 2.4G radio technology DESST receiver system, and it also supports the Futaba FASST series. The two-way JR/SPEKTRUM satellite receiver interface allows the supporting of two-way DSM2 satellite receiver at the same time. Most users can use the system without any external receiver, which has greatly simplified the complexity of the system and improved the security of the remote control system.

DJI DBUS ADAPTER module Supported

The A2 supports the DJI DBUS ADAPTER module, which can provide eight-way input or output. Users can use the traditional receiver through this module (for specific functionality, please refer to the DBUS ADAPTER introduction).

S-Bus and PPM Receiver Supported

The A2 is equipped with an interface for PPM and Futaba S-Bus receivers. It also has a reserved input mode for those users who cannot use the built-in receiver. With the support of PPM and S-Bus receiver the internal wiring is more concise.

More output interfaces

The A2 is equipped with a minimum of twelve output channels, which allows users to greatly extent the advantages of A2.

9 TYPES OF MULTI-ROTORS AND A CUSTOMIZED MOTOR MIXER

The A2 supports 9 types of traditional motor mixer:
Quad I, Quad X
Hexa I,Hexa V, Hexa Y, Hexa IY
Octo X, Octo I,Octo V
It’s a UAS that targeted at commercial and industrial multi-rotor platforms with simple configuration, easy installation and stable performance.

Bluetooth Module and New Assistant Software for Smartphone

The A2 provides assistant software for iPhone4s, iPhone5, iPad3, iPad4, iPad Mini, iPod5. You can do parameter adjustments at any time on your mobile devices, using only an LED indicator with a built-in Bluetooth module which makes it easier and convenient. It uses low power Bluetooth to minimize the power consumption of your mobile devices. It is easy to use and will automatically save your last connection records. The password mechanism ensures your safety link. Parameters can be automatically synchronized to the Cloud Server and can be restored immediately when you changed your mobile devices.

Power Monitoring Unit

The power management unit (PMU) is designed for the A2 to solve the high power consumption. It contains two power outputs for the entire A2 system and receiver separately, a battery voltage monitor, and two CAN-Bus interfaces.

Built-in Damper

Small size and weight allow easy installation in tight space, it simplifies the installation process, for various aircraft sizes.

Dual CAN-Bus system

The A2 system has a dual CAN-Bus design, which means that the system data throughput will be doubled and the extensibility is improved.

Precise Position and Altitude Hold

With the new generation GPS Module, the multi-rotor will have position and altitude locked accurately even in windy conditions. Hovering accuracy is approximately 2m horizontal and 0.5m vertical.

High Accuracy and intuitive Flight experience

With the A2, flying a multi-rotor will be as easy as driving a car. The pilot is released from the stress of controlling the multi-rotor and able to pay more attention to other tasks, instead of focus on flying.

Multiple flight control mode/ Intelligent Switching

It offers four types of control modes: GPS Mode (with GPS module), Atti. Mode 1, Atti. Mode 2, Manual Mode. The pilot can switch between the four modes to achieve different flight characteristics. The Flight controller also can adjust automatically within the changing flight environment and intelligently switch between GPS Mode and Atti. Mode to make sure the flight is safe. In manual mode position the operator can choose between manual and attitude 1.

Intelligent Orientation Control (IOC)

Usually, the forward direction of a flying multi-rotor is the same as the nose direction. By using Intelligent Orientation Control (IOC), wherever the nose points, the forward direction has nothing to do with nose direction:
In course lock flying, the forward direction is the same as a recorded nose direction. In home lock flying, the forward direction is the same as the direction from home point to multi-rotor.

Point of Interest (POI)

A2 has a new function: Point of Interest. 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 remote controller. The aircraft could achieve a circle flight around the point of interest with the nose in the point in an area of 5 meters to 500 meters radius, when the rolling command is given. This function is easy to set and simple to operate, it is suitable for all-round shooting of a fixed scenic spot.

RTH Switch from Transmitter

In addition to the function of failsafe RTH, the A2 now has a new function of RTH switch from transmitter. There is no need to turn into failsafe.

Enhanced Fail-Safe and Auto Go Home/Landing

Enhanced fail-safe is the feature to ensure that the multi-rotor will hover automatically if it loses RC signal. After losing the signal in a certain time period, A2 will calculate the safest way to return the helicopter to the home position. The helicopter will hover over your GPS start point and land automatically. This feature will guarantee the safety of your expensive payload and equipment.

Two Levels Low Voltage Protections and Auto Go Home

In order to prevent your multi-rotor from crashing or other harmful consequence caused by low battery voltage, we have designed two levels of low voltage protection. You can choose to not to use them, but all two level protections have LED warning as default. First level will blink yellow light continuously; second level will blink red light continuously. Compare the Go Home and Landing of low voltage protection and the Go Home and Landing in Enhanced Failed-safe, the generations of Home Location are the same; the Go Home routes are the same; the difference is that there is no hovering before landing in low voltage protection.

Multi-rotor One-power Output Fail Protection

In most conditions, the whole multi-rotor will retain good attitude and rotate around the frame arm with no power output, due to imbalanced mechanical structure and external environment. Rotating is mainly caused by payload and external environment. When payload is heavier, rotating speed is faster. On rotating, the hexa-rotor physical structure can cause rudder to become out of control. The humanistic protection function from A2, in Attitude or GPS Mode, keeps attitude under control even with any one power output failed and highly reduces crash risk.

Upgrade to Ground Station Control System

A2 can be upgraded to ground station (and iPad ground station) which is a more powerful unmanned platform to satisfy the high requirements of the customers.
The 50 waypoints are opened to the public for free. Besides the 3D map, it also contains such ground control functions as joystick/keyboard control, one key takeoff and click & go.

Other features

In addition to the above functionalities the A2 also has the functionality such as: 2-axis gimbal stabilization function; the HOME point/instruction function; the compass error alarming function.

Accessories supported

The A2 is perfectly matched to the iOSD and the ZENMUSE series gimbal, which provides the most comprehensive performance for the professional users.

Das ist doch exakt das gleiche was auf der von mir verlinkten Webseite zu finden ist, sogar auf Deutsch. Also verstehe ich nicht warum so eine zusätzliche Kopie notwendig ist, man hätte auch gleich die Links reinstellen können...

... und bitte immer gleich alles aus einem Post zitieren, das macht es so übersichtlich ...

Wenn die Leute immer gleich die Website lesen würden, gäbe es nur 10% Fragen, daher wenn mal die Website zum User kommt, dann winkt zwar der Pfahl mit dem Zaun, aber gelesen wird es immer noch nicht.

Find ich eine runde Sache, ist nicht viel teurer als das WMK, 50 Waypoints. Das mit dem integrierten Receiver find ich gut, für alle die sich nicht damit herumärgern möchten können jetzt einfach die entsprechende Funke ordern und fertig.

Was mich etwas stutzig macht, ist der Text zum "Dual Can Bus System", vor allem wenn man zwischen den Zeilen liest. Also vor allem, dass damit die "Stability" "improved" wurde, was bedeutet, dass es etwas zum "improven" gab. Also das ev "non-critical-data" ev. am WKM den Bus zugemüllt hat.

Sind die 50 Wegpunkte schon von Hause aus dabei? Ich hatte die Links zu dem französischen Shop weiter oben so verstanden, dass die zusammen mit der Groundstation extra gekauft werden müssen (mein Schulfranzösisch ist allerdings ziemlich mau ;))

Außerdem bin ich etwas irritiert hinsichtlich des Spektrum Equipments. Meinen die das mit DSM2 ernst? Alles Andere als DSMX ist doch eigentlich nicht mehr akzeptabel.

Mein schulfranzösich ist quasi nicht vorhanden
Aber mein selbst beigebrachtes englisch sagt mir das die wegpunkte mit bei sind
Wenn du ein iPhone 4S oder iPad 2 hast ...
