FAQ

Aircraft
What is the ingress protection (IP) rating of M350 RTK? Can I fly the drone in the rain?
M350 RTK is IP55 rated.
The IP rating is not permanently effective and may decrease due to wear and tear. Do not fly in rain heavier than 100 mm/24 hr.
Which propellers come with M350 RTK?
M350 RTK comes with the standard 2110s Propellers. You can also use the optional 2112 High-Altitude Low-Noise Propellers.
Can I use the propellers of M300 RTK on M350 RTK?
Yes, but only one type of propeller can be used simultaneously. Do not mix two types of propellers during use.
Can I replace the propellers of M350 RTK by myself?
Yes. When replacing the propellers, please also replace the corresponding screws and attach a proper amount of threadlocker (threadlocker 243 is recommended) to the surface of the new screws.
What do I need to operate the DJI 4G Dongle legally in the UK?
To operate a drone fitted with a DJI 4G Dongle in the UK you must:
1. Apply for an Ofcom UAS (Unmanned Aircraft Systems) Licence.
2. Seek written permission for airborne use of mobile network user equipment and use a network SIM card specifically authorised for 4G UAS operations, if directed by the network.
Further details are referenced in Ofcom licensing guidance.
Depending on the weight of your drone, you may need to register as an operator and obtain an operator ID from the CAA. To apply for an operator ID, visit the CAA website: Registering a drone or model aircraft | UK Civil Aviation Authority.
How do I apply for an Ofcom UAS licence in the UK?
For the Ofcom UAS Licence, visit the Ofcom website.
Ensure you meet all requirements and guidelines provided by these authorities.
Can I use a standard network SIM for 4G Dongle operations in the UK?
No, a standard network SIM is not compliant with the legal requirements for operating the 4G Dongle in the UK. You must obtain a dedicated SIM authorised for UAS operations through your network provider.
Battery
How long does it take to fully charge two TB65 Intelligent Flight Batteries?
With a 220V power supply, it takes approximately 60 minutes to fully charge two TB65 Intelligent Flight Batteries and approximately 30 minutes to charge them from 20% to 90%.
With a 110V power supply, it takes approximately 70 minutes to fully charge two TB65 Intelligent Flight Batteries and approximately 40 minutes to charge them from 20% to 90%.
Does M350 RTK support the TB60 Intelligent Flight Battery?
Yes, but only two TB60 batteries can be used simultaneously. Do not mix TB60 and TB65 batteries during use.
Why does the battery heat up during long-term storage?
During long-term storage, the battery will automatically discharge to approximately 50% to ensure storage safety and extend battery life. It is normal for the battery to feel slightly warm during this process.
Can I use the TB65 Intelligent Flight Battery in low-temperature environments?
Yes. The operating temperature of the TB65 Intelligent Flight Battery is -20° to 50° C (-4° to 122° F). When the battery is used in low-temperature environments, the battery life will be reduced. Please schedule the flight time properly. To ensure optimal performance, it is recommended to keep the battery temperature above 15° C (59° F) before flying.
For charging in environments of -20° to 5° C (-4° to 41° F), the battery will automatically heat up before starting the charging process. Once installed on the aircraft and powered on, the battery, if at a low temperature, will automatically heat up to maintain a temperature of approximately 16° to 20° C (60.8° to 68° F).
What is the service life of the TB65 Intelligent Flight Battery?
There are three ways to calculate the service life, including 12 months, 400 cycles, and 120 days of high-power storage. The final service life depends which comes first.
Can I carry the TB65 Intelligent Flight Battery onto an airplane?
The energy of the TB65 Intelligent Flight Battery is 263 Wh, so it cannot be carried onto an airplane according to airline regulations.
How do the fans of the BS65 Intelligent Battery Station work?
The fans automatically turn on or off and adjust rotation speed according to the ambient temperature and battery temperature.
How many batteries can be charged by the BS65 Intelligent Battery Station simultaneously?
The BS65 Intelligent Battery Station can store eight TB65 Intelligent Flight Batteries and four WB37 Intelligent Batteries at the same time. It can charge two TB65 batteries and one WB37 battery simultaneously. Batteries with the highest battery level will be charged first, followed by others with lower levels.
Remote Controller
How do I charge DJI RC Plus?
The charger for the remote controller is integrated in the BS65 Intelligent Battery Station. You can charge the remote controller by connecting it to the battery station with the USB-C cable.
Is M350 RTK compatible with the remote controller of M300 RTK?
No.
Can I use DJI RC Plus with M300 RTK or the M30 Series?
Yes. Please update the firmware of DJI RC Plus to v01.02.04.40 or higher, select the corresponding drone model in DJI Pilot 2, and then complete the linking.
Payloads
Which payloads are compatible with M350 RTK?
Zenmuse H30, Zenmuse H30T, Zenmuse L2, Zenmuse H20N, Zenmuse L1, Zenmuse P1, Zenmuse H20, Zenmuse H20T and third-party-certified payloads developed based on the DJI Payload SDK.
How many payloads can be mounted on M350 RTK simultaneously?
M350 RTK supports mounting up to three payloads simultaneously, with the single upward gimbal and dual downward gimbals used together.
RTK
Can I use M350 RTK for precision surveying?
M350 RTK can perform precision surveying when equipped with Zenmuse P1, Zenmuse L1, or a third-party payload developed based on the Payload SDK. For details, please leave your contact information at the bottom of the page, and we will contact you as soon as possible.
Does M350 RTK support the post-processed kinematic (PPK) technology?
When M350 RTK is mounted with Zenmuse P1 or Zenmuse L1, the task folder stores photos/point clouds, GNSS observations, and image log files, which are used for PPK post-processing calculations.
How does M350 RTK obtain real-time differential data?
M350 RTK supports obtaining real-time differential data in the following ways:
1. Connect the aircraft to the D-RTK 2 Mobile Station (supporting RTCM3.2 protocol) via DJI Pilot 2.
2. Connect the remote controller to the custom Network RTK service based on NTRIP protocol (supporting RTCM3.0/RTCM3.1/RTCM3.2 protocols) via a Wi-Fi hotspot.
Can one D-RTK 2 Mobile Station support multiple M350 RTK simultaneously?
Yes, there is no limit to the number of drones that can be used simultaneously.
Firmware
How do I update the firmware?
You can update firmware in the following ways:
1. Connect the aircraft to a computer and use DJI Assistant 2 (Enterprise Series) to update the firmware of the aircraft, remote controller, and D-RTK 2 Mobile Station.
2. Use DJI Pilot 2 to update the firmware of the aircraft, remote controller, and Intelligent Battery Station.
3. Visit the official DJI website to download the offline firmware update package for the aircraft, Intelligent Battery Station, and remote controller. Then, insert an SD card storing the firmware package into the remote controller for offline update.
For details, please refer to the user manual.
SDK
What changes have been made to the E-Port compared to the Onboard SDK port?
E-Port is a new-generation expansion port of DJI Enterprise drones. E-Port has the same pin definition as the Onboard SDK port, but the USB link requires that the third-party payload be used as a secondary device (opposite to the Onboard SDK port). In terms of software, E-Port only supports Payload SDK V3 or later versions, and is not compatible with Onboard SDK. For technical support, please contact dev@dji.com.
Which kinds of SDK development does M350 RTK support?
M350 RTK supports Payload SDK, Mobile SDK, and Cloud API. For technical support, please contact dev@dji.com.
Can I use third-party Payload SDK payloads compatible with the M200 Series and M300 RTK directly on M350 RTK?
Third-party payloads developed based on the Skyport V2 or X-Port can be compatible with M350 RTK after updating the adapter and third-party firmware. For other questions, please contact the corresponding payload provider or DJI Support.
Other
Which accessories are compatible with both M300 RTK and M350 RTK?
