Can the Matrice 400 be flown remotely through FlightHub 2?

Yes. DJI's FAQ says it supports remote control of flights, gimbal cameras, PSDK accessories and route-related functions through FlightHub 2. The aircraft connects through its RC Plus 2 Enterprise Enhanced, which needs an internet link.

What is the Matrice 400's maximum payload and flight time?

DJI lists a 6 kg maximum payload on the screw-locked third gimbal connector at sea level, and up to 59 minutes of flight with an H30T. With the AP100 parachute fitted, flight time is about 53 minutes.

Does the Matrice 400 support dual control?

Yes, DJI's FAQ confirms dual control. It also supports two enhanced 4G modules and onboard relay of one additional Matrice 400.

Can the Matrice 400 hot-swap batteries?

Yes. It uses a single TB100 battery, and a built-in capacitor keeps essential components powered during a swap. If the swap finishes within 45 seconds, the aircraft resumes operation quickly.

Is the Matrice 400 compatible with Matrice 350 accessories?

No. DJI says Matrice 400 and Matrice 350 accessories are not compatible with each other, and the M400's RC Plus 2 Enterprise Enhanced does not support the M350 RTK.

Is the Matrice 400 available in the US?

As of October 2026, yes. It was authorized before the FCC's December 2025 Covered List action. A proposed FCC notice could end sales of foreign LiDAR and thermal configurations after a wind-down, but it was not final.

Updated October 16, 2026

The DJI Matrice 400 is DJI's long-endurance heavy enterprise platform: 15.8 kg at takeoff, up to 6 kg of payload, 59 minutes with an H30T, and a sensing stack DJI describes as "power-line-level obstacle sensing". For remote operations the more important line is in its FAQ: through DJI FlightHub 2 it supports remote control of flights, gimbal cameras, PSDK accessories and route functions. It also supports dual control, two 4G modules and airborne relay through a second Matrice 400. That combination makes it the DJI aircraft best suited to a remote pilot flying long linear work, a power line, a pipeline or a rail corridor, while a crew on the ground handles launch, batteries and recovery.

Why the sensing stack matters for corridor work

Wires are what make corridor inspection dangerous. They are thin, hard to see on compressed video, and exactly where the aircraft needs to be. The Matrice 400 specs list a horizontal rotating LiDAR rated to about 35 m for 21.6 mm steel-core aluminum conductor, six-direction mmWave radar rated to 36 m for 12 mm wire and 50 m for 21.6 mm wire, an upper 3D ToF LiDAR, a downward 3D infrared sensor and fisheye binocular vision. The FAQ adds that power-line sensing works at up to 25 m/s facing a main line and up to 17 m/s with both main and distribution lines present.

What it gives a remote pilot

A margin that does not depend on spotting a conductor on a delayed video feed. When the pilot is a few hundred milliseconds behind, the aircraft's own sensing is what stops it short of the line.

What it does not do

DJI's FAQ says fast-moving objects cannot be actively avoided. Birds, other aircraft and swinging loads remain the pilot's and observer's job.

What the crew maintains

Keep the rotating LiDAR's protective cover on when not in use and clean the dome when dirty. A dirty dome on a corridor job is a sensing failure waiting to happen.

Regional caveat

DJI notes the mmWave radar may be restricted in some regions. Confirm what is enabled on your aircraft before you count on it.

How a Matrice 400 is flown remotely

There is no DJI dock for the Matrice 400 on its spec sheet, so remote flight runs through the controller. DJI's Cloud API architecture connects an aircraft to the cloud through a gateway, here the RC Plus 2 Enterprise Enhanced running DJI Pilot 2, and from there to FlightHub 2 or your own platform. In practice that gives three ways to split the job:

Remote pilot, local crew

The crew powers up, runs the preflight and launches; the remote pilot flies the corridor or inspection from FlightHub 2, including gimbal and PSDK accessory control, and hands back for landing.

Dual control

The FAQ confirms dual control. Where a program uses it, the second controller can let an inspector concentrate on the camera while the pilot concentrates on the aircraft, or simply stand by as a backup.

Supervised routes

Planned waylines run with a remote pilot monitoring, ready to pause or take manual control. This is the mode that scales: the pilot watches the plan rather than flying every metre.

Decide who holds authority at every phase. With FlightHub 2 control, dual control and a local controller all possible on the same aircraft, the procedure has to name one pilot in command and say exactly how and when control moves. Ambiguity about who is flying is the failure mode, not the hardware.

Links: radio, 4G and relay

O4 Enterprise Enhanced

Up to 40 km under FCC rules in unobstructed, interference-free conditions, and roughly 1.5 to 40 km in real-world interference. The controller shows three 1080p/30fps live channels. DJI does not publish a latency figure on the spec page.

Dual 4G

Two DJI Cellular Dongle 2 interfaces on the underside and four 4G antennas. For a remote pilot this is the path that matters, since FlightHub 2 control rides on the internet connection, and two carriers give redundancy along a corridor that crosses coverage gaps.

Airborne relay

One Matrice 400 can relay one additional Matrice 400 at a time, extending the link behind terrain or structures. DJI notes this is unavailable where 5 GHz is not supported.

Delay on a browser-flown aircraft is the sum of the radio hop, the cellular uplink, the cloud and the pilot's own connection. That is acceptable for wayline supervision and slow manual inspection at standoff distance, and not for close work around hardware. Our latency guide covers budgets by task.

Payloads and data

DJI lists the Zenmuse L3, H30, H30T, L2 and P1 as compatible gimbal cameras, plus the AP100 parachute, Zenmuse S1 and V1 accessories, Manifold 3 and the Cellular Dongle 2. Four E-Port V2 ports provide 120 W each, and with the E-Port HUB the aircraft supports up to seven payloads in total. Manifold 3 adds onboard compute for custom processing, and FlightHub 2 supports third-party algorithms on the Matrice 400.

Corridor LiDAR

Zenmuse L3 or L2 point clouds for vegetation clearance and conductor sag, tied to RTK at 1 cm + 1 ppm horizontal in fix mode.

Thermal and zoom

H30T imagery of insulators, splices and transformers, with the flight log recording where each frame was taken.

Photogrammetry

P1 image sets for structures and substations.

Delivery

Imagery, thermal, point clouds and flight logs tagged by site, asset, span and mission, so an asset owner can trace any finding back to the flight that produced it.

Other features that change the remote job

DJI's product page also lists Smart Detection paired with visible and thermal imaging, AR projection, and ship-based takeoff and landing, which matters for offshore and coastal work where the launch point moves. There is no DJI dock for the M400, but the FAQ mentions a TB100C tethered battery used with an ecosystem partner's drone dock, so docked or tethered setups exist outside DJI's own line. Each of these changes the checklist and the takeover plan, and each should be trained on the customer's own aircraft before it is used on a live mission.

Running a Matrice 400 program from a remote operations center

One-to-many supervision

Several crews can launch while one remote supervisor watches planned routes, with any manual flying or anomaly going to a dedicated pilot. How many aircraft one person may supervise at once is set by your approvals.

Mission planning

Corridor routes built span by span with standoff distances, speed limits under the power-line sensing thresholds, and planned relay or 4G handoff points.

Takeover

Triggers written per corridor (approaching crossings, loss of one 4G link, ADS-B traffic) and a drilled sequence for pausing, taking manual control or returning.

Airspace and visual observers

The ADS-B In receiver, with reception up to 20 km, shows cooperative manned traffic; non-cooperative traffic still needs observers or other means your waiver specifies.

Data delivery

Outputs and logs tagged by site and mission, with link and sensing events recorded for the safety file.

What a good Matrice 400 pilot does differently

Respects the hot-swap window. A built-in capacitor keeps essential systems powered during a battery swap, and DJI says the aircraft resumes quickly if the swap is done within 45 seconds.

Plans for the battery's heating behavior: below 20 °C the TB100 warms itself in the aircraft before flight, which takes time on a cold morning.

Remembers that 12 m/s is the wind limit for takeoff and landing, and that rain heavier than 100 mm in 24 hours is out of limits despite IP55.

Flies with the parachute fitted when the operation calls for it and plans around the shorter 53-minute endurance.

Matrice 400 vs Matrice 350 RTK

Against the Matrice 350 RTK (9.2 kg takeoff, 55 minutes without payload, O3 Enterprise to 20 km FCC), the M400 carries far more, flies longer with a payload, and adds LiDAR and radar sensing, ADS-B In, dual 4G and relay. The two do not share accessories, and the M400's RC Plus 2 Enterprise Enhanced does not support the M350. The M350 remains a capable on-site aircraft; the M400 is the one built for a remote pilot.

US regulatory notes, as of October 2026

FCC

Previously authorized foreign drones can still be imported and sold after the Covered List action, and the M400 was on DJI's US booth in September, per DroneXL. FCC notice DA 26-454 keeps firmware updates coming to at least 1 January 2029.

Proposed sales cut-off

DA 26-758 lists seven categories, including thermal imaging, LiDAR and aircraft of 55 lb or more at takeoff. The M400 is well under 55 lb, but LiDAR and thermal configurations fall in scope. Not final; owned aircraft would not be grounded.

Tariffs

From 3 September 2026, 25% on aircraft at or under 55 lb and 100% on thermal imagers; DroneXL reads an M400 with a P1 as 25%.

BVLOS

Visual line of sight (§107.31) and visual observer (§107.33) rules are among those the FAA can waive under §107.205. Part 108 was still at OIRA in the latest reporting, per PickDrones, so corridor BVLOS still runs on waivers.

How RoboPilots runs Matrice 400 programs

Your aircraft and FlightHub 2 workspace stay yours. We train a dedicated group of Part 107 remote pilots on your Matrice 400 configuration, corridors and procedures, including the handover routine with your ground crews, before they fly a live mission, and they work inside your approvals.

One-week trial

A short run on your aircraft and a real corridor sets the flights-per-pilot-shift baseline and tests the 4G coverage along the route.

Coverage

Shifts across time zones, including US Pacific, so long summer days are staffed end to end.

Data

Imagery, thermal, LiDAR and flight logs tagged by site and mission.
