Features:
Compact and highly integrated design.

Read to fly design
The hardware mounting and software tuning are all done prior to delivery. The Auto-Pathfinder is ready to fly the moment you unpack it, you just need to attach propellers, charge the LiPo and install the transmitter batteries before use.
Contains remote control unit.(Just add 4 x AA batteries)
Auto-Pathfinder contains a remote controller and receiver, The only thing you need to do is to add TX batteries (4x AA dry cell).

The 2.4 G ISM frequency makes the effective control distance up to 300 meters (can be impacted by the specific flight environment). The frequency hopping anti-interference design allows multiple remote controllers to work at the same time, and provides a reliable remote communications link.
Two flight control modes,including position hold
With the built-in MX autopilot system plus a GPS module, the Auto-Pathfinder has GPS Attitude and Attitude Control Mode. Pilots can switch between the two modes to achieve a particular flight experience.

Intelligent orientation control(IOC)
Auto-Pathfinder also has the Intelligent Orientation Control (IOC) function of the MX autopilot system. 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 the multi-rotor.
Failsafe & auto go home/landing
Auto-Pathfinder also has the fail-safe function of the MX autopilot system. This means when the communication between the Mx Controller and the transmitter is disconnected, the outputs of all command sticks from controller will go to the center position. If the GPS signal is good enough, the system will automatically trigger Return To Home and will land safely.

Low voltage protection
Auto-Pathfinder also has two levels of low voltage protection, a function of the MX autopilot system. It prevents your multi-rotor from crashing or other harmful consequences caused by low battery voltage. In the first level of protection, the LED indicator blinks and makes a sound of “Bi-Bi-Bi” to warn you. In the second level protection the system will trigger the Auto-Pathfinder to land automatically.

Maximum flight speed 10m/s
The maximum horizontal flight speed of the Auto-Pathfinder can reach 10m/s and the maximum vertical speed is 6 m/s. The perfect combination of speed and stability.

High intensity led lights,aids orientation during flight
Under each arm of the Auto-Pathfinder there are some high intensity LED indicators which are used to help you to see the orientation during flight.

GoPro camera mount(camera not included)
Auto-Pathfinder has an external removable camera mount for you to mount light cameras (GoPro for example) or other video shooting electronic equipment.
Includes 1 3S LiPo battery (capacity 2700mAh, weight only 180g) and a balance charger.
15-20 minutes Flight time.

We do have a complete line of re-placement and spare parts.

Tech. Notes:
Take the time to properly calibrate the controller, the compass, the accelerometers. It is easy to calibrate if you use the APM Mission Planner software, as it has instructions and live feedback while the CX20 is plugged in in via USB.If you need the direct link , let us know we will email it to you !
2) DO NOT use a WiFi camera, as it may interfere with the receiver of quadcopter , may result in loss of control
3) DO NOT upgrade the firmware, it will show an error, such as"no data-flash" or no log written.
