A: The basic frequency memory of PIXHAWK is 180MHz, the RAM memory of PIXHAWK is 260K, and the Flash memory is 2MB.

A: No, it's not compatible because the firmware is different.

RadioLink flight controller PIXHAWK, Mini Pix and TURBO PiX are compatible with the firmware from APM only.

A: Yes

A: Since Dec.29, 2019, ArduPilot official has updated the firmware of arducopter(multirotor), arduplane(acrobatic) and ardurover(car/boat) to V4.0. However, the sensor integrated of firmware V4.0 has been modified, making that of some RadioLink PIXHAWK doesn’t function normally as the progress bar doesn’t move when calibrating the compass. If this problem encountered, please follow below steps:

Note The progress bar should be moving when calibrating compass, meaning PIXHAWK functions and is compatible with firmware V4.0. Then there’s no need to follow below steps

1. Connect the PIXHAWK to a GPS module with compass

Because it is the internal sensor driver modified with the V4.0 firmware and the external sensor remains. To work with an external one, it can function normally.

2. Use the firmware of V3.X instead of V4.0

A: Yes. PIXHAWK supports RTK without any settings on it.

A: NO.

A: NO.

A: No, it can’t. If PIXHAWK is used for a fixed-wing and connected to a single ESC, the ESC current can be up to 90A; If it is used for a multi-rotor and connected to more than 2 ESCs, the total current of all ESCs cannot exceed 90A. So if it is connected to 4 ESCs, the current of each ESC should be 20A or lower.

A: Yes.

Connect CrossFlight/Mini Pix/PIXHAWK to Mission Planner---CONFI---Full Parameter List---search SERIALX. Change the value of SERIALX_BAUD to 115, and the value of SERIALX_protocool to 23 ---Change the value of RSSI_TYPE to 3 --- RC_options check options: suppress CRSF mode/rate message for ELRS systems (Note: When using an ELRS receiver, you also need to check the option Use 420kbaud for ELRS protocol.) ---Click “Write Params”.

(Note: X represents the telemetry port. If TELEM1 is used, X = 1, then please search SERIAL1 in Full Parameter List)

A: The pitch channel is reversed by default foropen-sourced transmitter. After connecting the flight controller, enter Mandatory Hardware—Servo Output interface, and check the "Reverse" box for the corresponding pitch channel.

A: Because the receiver signal is not recognized in Mission Planner. Please connect the CRSF receiver to the data transmission port of the flight controller, and modify the parameters of the data transmission port to 23 in Mission Planner.

A: Mission Planner does not support the Apple MAC system, but supports both Windows and Android systems.

QGroundControl Mission Planner supports Windows, Android systems, and the Apple MAC system, but needs to download from its official website.

http://qgroundcontrol.com/

A: Yes, but you can only install the firmware by loading custom firmware when using QGroundControl. You cannot directly click on the model to install the firmware for PIXHAWK, because it is possible to install the PX4 firmware by clicking on the model. And RadioLink PIXHAWK is not compatible with PX4 firmware.

A: You can use a Bluetooth data link to connect the flight controller to the Mission Planner. Below is a detailed guide on how to connect the flight controller to the Mission Planner by using a Bluetooth data link.

https://ardupilot.org/copter/docs/common-mission-planner-bluetooth-connectivity.html?highlight=bluetooth

A: Yes. Below is the link to explain the setup. Click your device and then you can get the details on how to connect and set them up.

https://ardupilot.org/dev/docs/companion-computers.html

A: Check the value of MOT_SPIN_ARM in Mission Planner. If the value of MOT_SPIN_ARM is set to 0, the motors will not spin after the arming is successful, and they will only spin if the throttle joystick is pushed.

A: Please troubleshoot by following the below steps: 1. Check whether the LED indicator of the receiver is blue/purple, that is, SBUS signal output. RadioLink flight controllers support SBUS signal (Most of them also support PPM signal). The blue/purple LED indicator of RadioLink receivers represents the SBUS signal working mode. If the LED indicator of the receiver is not in blue/purple, please short press the binding button to switch to blue/purple. The signal switching methods are different for different receivers. Please refer to the instruction manual of your receiver to switch signals: https://www.radiolink.com/receivers 2. Check whether the connection of all device is correct. The RC IN port of the flight controller needs to be connected to the SBUS signal channel of the receiver, and the positive and negative poles of all connections must be connected correctly.

A: You need to adjust the parameter of the flight controller. Connect the flight controller to Mission Planner. Search for SERIAL1_PROTOCOL in the Full Parameter List. Select MAVLink2, and click Write Paras to save the modification.

A: NO.

A: The ESC pins of PIXHAWK only supply power for external devices (such as servos), not for the flight controller.

A: You can connect the positive and negative poles of the ESC or BEC module to the positive and negative poles of the POWER port of the flight controller.

A: If the flight controller and the GPS with compass internal connect to the Mission Planner at the same time, the Compass #1 indicate the compass of GPS, meanwhile, the "Externally mounted" and the GPS direction select box will pop out on the Mission Planner. The Compass #2 indicate the compass of the flight controller internal.

Calibrate interface will shows as picture below when use with GPS.

If the GPS mounted with the same direction with flight controller, then it need not to setup the direction of GPS in Mission Planner but if you mounted the GPS with the different direction of PIXHAWK, you have to setup the right direction in the Mission Planner.

A: If the flight controller and the GPS with compass internal connect to the Mission Planner at the same time, the Compass #1 indicate the compass of GPS, meanwhile, the "Externally mounted" and the GPS direction select box will pop out on the Mission Planner. The Compass #2 indicate the compass of the flight controller internal.

Calibrate interface will shows as picture below when use with GPS.

If the GPS mounted with the same direction with flight controller, then it need not to setup the direction of GPS in Mission Planner but if you mounted the GPS with the different direction of PIXHAWK, you have to setup the right direction in the Mission Planner.

A: The setting steps can follow this manual by click the link below:

https://ardupilot.org/plane/docs/quadplane-support.html

A: Connect the RadioLink Mission Planner to flash the latest firmware. If it's notified that the latest firmware is already exist, flash again by changing another model e.g. ACROBATICS . If the problem still cannot be solved, it's probably the barometer is broken. Please send mails to after_service@radiolink.com.cn to furthur confirm and ask for accessory purchase.

A: It means that there's problem about the compass. It can be solved by either calibrating the compass or removing possible disturbance resources to the compass.

A: Yes. This parameter can be modified at LAND_SPEED with the minimum speed as 30cm/s.

A: It is because the hardwares of Turbo Pix and Mini Pix have been upgraded. FC of V2.0 can ONLY flash firmware with the latest RadioLink Mission Planner V1.3.50. But FC of V1.0 can flash firmware with RadioLink Mission Planner either of V1.3.49 or V1.3.50.

A: There are two possible reasons

1) The memory card is not well inserted or doesn't function.

2) The firmwares need to be flashed.

A: It comes from the wrong direction of motor or the reversed installation of the propellers. Check the motor and propellers.

A: Firmware fmuv2 or fmuv3 will be chosen depending on the version of PIXHAWK:

① the V3.0 PIXHAWK should upgrade the fmuv3 firmware

② the other version(except V3.0) of PIXHAWK supports 1M fmuv2 firmware by default. It also supports 2M fmuv3 firmware. You can download fmuv3 firmware from the ArduPilot website and then upgrade the firmware.

A: Since ardupilot updated the firmware recently, when users use PRM-03 with RadioLink transmitters AT9S Pro, AT9S, AT9, AT10II, AT10 and the ardupilot pixhawk flight controller which with the V4.1 or above firmware, only telemetry of model voltage is supported, telemetry of other OSD data is not supported. Please solve the problem by changing the value of SERIAL1-PROTOCOL and SERIAL2-PROTOCOL in Mission Planner.

A: The setting methods are as follows:

1. Search SERVOx_FUNCTION in the Full Parameter List, and set data to -1 (x means channel)

2. Search RELAY_PIN and modify it to the value of the corresponding channel (The value corresponding to channel 1 is 50, the value corresponding to channel 2 is 51, and so on)

3. If there are multiple relays, set RELAY_PINx (x represents relay, RELAY_PIN2 represents relay 2, etc.)

4. Set the transmitter channel to control the high level/low level of the relay. Search RCx_OPTION, (RCx means the transmitter channel, RC7 means the 7th channel of the transmitter, etc.), and select Relay On/Off, which means controlling the first relay

5. If there are multiple relays, set multiple channels as above, search RCx_OPTION, and select Relayx On/Off (x means relay, for example: If the 5th channel of the transmitter controls the second relay, select RC5_OPTION as Relay2 On/Off)

6. Restart the flight controller

A: Firmware version Airplane_v4.0.5 has been upgraded. Set Fail Safe in all parameter list.

A: Yes.

A: Mini Pix supports PPM and SBUS signal input. So Mini Pix is compatible with receivers which support PPM and SBUS output. Pls check if your receiver support PPM and SBUS output.

A: Yes. Click the link below to view related tutorials:
