ZERO TECH adheres to continuous innovation and improvement. With the new firmware, new attitude stabilization algorithm and optimized hardware structure, the YS-X4 V2 provides better flight performance. The innovative All-in-one design simplifies installation and saves space and weight. It contains inner damping, controllers, 3-axis gyroscope, 3-axis accelerometer and barometer in its light and small Main Controller. It can measure flying altitude and attitude and therefore can be used for autopilot/automatic control.

For those flying tasks which do not allow preset waypoints or need to change flying target accordingly, click any target point on the google map, click "Click and Go" button, the aircraft shall fly to the target point automatically as command. Easy operation easy to go.

It is quite convenient and easy to get real-time altitude and distance information during the whole flight with voice broadcast function, no need to distract your attention to check the GCS and quickly get real-time status information.

Enable phone attitude control mode in phone remote control mode, to control the aircraft by tilting your phone forward/back, left/right direction and its flying direction is same as phone tilt direction. For example, forward or back tilting phone, the aircraft shall move forward or back, left or right tilting phone, the aircraft shall move left or right etc. After quitting from phone attitude control mode, it will auto-switch back to phone remote control mode.

While using smartphone as GCS, in GPS hover mode and all transmitter sticks stay in the middle position, after enabling follow me, the aircraft shall lock its head direction and auto-fly by following the pilot via phone GPS location.

Each YS-X4 V2 comes with a professional WIFI module, private smartphone/tablet or PC can be used as ground station via WIFI communication. WIFI module is built-in two communication mode(Router mode and PP mode), user can setup the mode to be PP mode according to your favorite which can fly with no need router, greatly bring convenience to flight.

YS-X4 V2 supports nine types of multi-rotor, which meets the different needs of the enthusiasts.

Quad I, Quad X;

Hexa I, Hexa V, Hexa Y, Hexa IY;

Octo X, Octo I, Octo V; ( Doesn't support Servo Gimbal on Octocopter)

Waypoints of YS-X4 V2 can be set to the number of destinations up to 128, users can carry out for each waypoint special settings, such as height, residence time, flight speed, longitude and latitude etc. to meet the complex requirement of the routes operating and flying task, intelligently adjust flying speed and altitude. Meanwhile you can setup shutter on each waypoint or change the waypoint route during the flight.

YS-X4 V2 supports Android phone/tablet,PC as terminal handheld GCS to adjust the parameters, simple software installation assists you to control real-time flight and adjust the gains easily, which makes the adjustment sensibility easier to be adjusted, brings you brand-new flying experience.

Compatible with almost all radios - PCM or 2.4Ghz, simple application, provide more options.

Humanized fail-safe is the feature to ensure that the multi-rotor will hover automatically when it loses signal. After loss of signal for a certain period of time, YS-X4 V2 will auto-switch to be hover status (Keep waypoint flying for 5 more seconds when during GPS waypooints flight), it shall keep auto-flying as waypoints route to make sure the normal flying task if signal recover within 5 seconds, if not recover after 5 seconds, you can enable auto-back/landing function.

YS-X4 V2 has built-in low voltage alert function, when voltage goes down to be a certain low value, phone shall remind users to pay attention to operation by vibration, when voltage goes down lower than the low value, phone shall keep a constant and high-frequency vibration to alert user must land the aircraft urgently.

This function means that when the aircraft is in attitude or GPS attitude mode, and one of the motors stops, the aircraft will retain good attitude and rotate around the frame arm with the stopped motor. In this condition, the aircraft is still under control and returns home safely and highly reducing the risk of a crash.

The latest attitude stabilization algorithm not only inherits the outstanding flight stability of ZERO TECH products, but also provides excellent maneuverability with flexible and stable flying performance, and gives the hobbyists a wonderful flight experience.

YS-X4 V2 supports multiple flight control modes. It can be intelligently switched among Manual Stabilization Mode, GPS Attitude Mode (Auto Hover /Auto Navigation /Auto Go Home/Landing), Phone Attitude Mode, Phone Remote Control Mode.

YS-X4 V2 firmware can be upgraded easily online, brings you a new flying experience.

YS-X4 V2 uses high-precise air pressure sensor, measure precision 10cm, it calculates the attitude and vertical velocity by Kalman filtering method, controlling precision is 20cm. With YS-X4 V2, the multirotors will have precise position and altitude lock in windy conditions, precise hovering in less than 1.5m horizontal and 0.5m vertical.

After connecting OSD, flight data can be added to video, to assist you in getting a complete and ideal flight.

Usually, the forward direction of a flying multi-rotor is the same as the nose direction. By using Intelligent Orientation Lock, 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.

Motor Arm

After landing or before take-off, only if it is manual mode and the throttle stick is at the bottom position, the insurance can be enabled after 5 seconds; After the insurance is enabled, even if you push the throttle stick, the motors will not work. But you can arm the motor by clicking " enable insurance" in GCS or moving transmitter's stick as V shape to make the motors start again.

Motor Disarm

In manual mode , the motors will stop rotating when pulling throttle stick back to the bottom. In GPS mode, pulling throttle stick to the bottom only decrease the altitude. After landing your aircraft (Suggest you switch to manual mode immediately), pull back the throttle to the bottom and motors would stop slowly till completely lock stop.

The default parameter settings are preset for you to achieve a normal flight, and also supports remote parameter adjustment by using a control slider on the TX during flight in order to obtain better performance.

The Independent LED module makes the indication of the flight status and the system status to the ground much clearer. The pilot can get information more quickly and more conveniently, even at night, he/she can get real-time flight information feedback through the LED flashing frequency and colour.

The gimbal stabilization module is compatible with almost all 2-axis gimbal systems. The system will adjust the gimbal and camera according to the attitude of the aircraft after setting the parameters the first time.
