Choose one of four relay topologies

The relay aircraft supports the communication path while the main aircraft performs the task. DJI demonstrates four combinations of controllers and aircraft. The arrangement determines who can control each aircraft and which signal information appears on each controller.

Choose the topology around the crew and the planned signal path. Sketch the controller, relay and main-aircraft positions before setup, and label each physical aircraft so its on-screen role is easy to confirm.

  1. Single-Relay, Single-Controller: one controller, one relay and one main aircraft.
  2. Single-Relay, Dual-Controller: two controllers, one relay and one main aircraft.
  3. Single-Relay, Dual-Controller, Triple-Aircraft: two controllers, one relay and two main aircraft.
  4. Dual-Relay, Dual-Controller: two controllers, two relays and one main aircraft.

Open Relay Network Setup and identify controller roles

Power on the devices and place them together near the controller. The tutorial builds the triple-aircraft arrangement and explains that the other topologies use the same setup process with different device counts.

A Main RC controls only its main aircraft. A Relay RC controls the relay aircraft. A Main & Relay RC can switch between its main and relay aircraft. Make these responsibilities explicit before connecting the network.

The most complex arrangements shown contain three aircraft and two controllers: up to five devices are selected together during setup.

  1. Open Relay Network Setup on the DJI Pilot 2 homepage.
  2. Select the usage scenario that matches the intended topology.
  3. Identify the Main RC, Relay RC or Main & Relay RC responsibilities in the selected arrangement.

Put aircraft into findable mode

Press each aircraft's power button three times in quick succession. Sequential blinking of the power indicators confirms findable mode. On the device-search page, the controller continuously searches for nearby discoverable devices.

Discovery order initially assigns the roles. That makes the next step important: the first aircraft found is not automatically the aircraft your crew intended for that role.

The on-screen note states that restarting the device exits findable mode. If you restart during preparation, repeat the discovery step before continuing network setup.

A device that is not detected for five seconds is treated as offline and disappears from the device list. Keep the devices powered and together while completing discovery.

  1. Press each aircraft power button three times quickly.
  2. Confirm its power indicators blink in sequence.
  3. Open the device-search page and wait for the aircraft to appear.

Assign and physically verify aircraft roles

Drag the aircraft icons on the controller screen to change their roles. To identify a particular physical aircraft, press its power button once; its app icon flashes brightly for three seconds. Use this check for every aircraft before moving on.

  1. Drag icons into the intended relay and main roles.
  2. Press one aircraft's power button once.
  3. Match it to the icon that flashes for three seconds.
  4. Repeat until the crew can identify each aircraft and its role.

Join the second controller and finish linking

On the second controller, open Relay Network Setup and join the network. The tutorial uses Join Networking, shows the aircraft icons, and confirms successful setup with Linking Successful. Follow any setup-failure prompt before continuing.

Keep the joining controller on its linking page and continue on the controller that initiated network setup. The joining controller is now discoverable by that network; leaving the page interrupts this setup stage.

  1. Open Relay Network Setup on the second controller.
  2. Tap Join Networking and confirm the displayed aircraft.
  3. Complete the prompted setup and look for Linking Successful.
  4. To leave the established network, follow the demonstrated five-second aircraft power-button hold to relink, or restart network setup.

Read the signal for the selected topology

On a Main RC, the video-transmission indicator is the Composite Signal for the aircraft being operated. When controlling a relay, the display exposes the relevant link segments. This lets the pilot distinguish an overall working-aircraft link from the individual sections that support it.

In the single-relay arrangements, the relay view shows controller-to-relay and relay-to-main links. In the triple-aircraft arrangement, each controller operates one main aircraft, and the Main & Relay RC can also switch to the relay.

In the dual-relay arrangement, the Main RC's overall signal is the weakest of the three segments. Relay Aircraft 1 shows Relay RC-to-Relay 1 and Relay 1-to-Relay 2. Relay Aircraft 2 shows Relay 1-to-Relay 2 and Relay 2-to-main. Review the weak segment before changing a relay position.

Switch aircraft and open Relay Split Screen

Tap the main or relay aircraft icon at the bottom of the screen to switch control where the controller role permits it. The camera view and signal display change with that selection. Confirm the selected aircraft before giving an input.

  1. Tap the intended aircraft icon to switch control.
  2. Verify the camera view and signal display changed to that aircraft.
  3. Hold R3 to open Relay Split Screen and view the other aircraft's auxiliary video stream.

Monitor the complete network during the mission

The tutorial shows AR positions when the two aircraft are more than 500 metres apart. HMS information and battery levels appear at the bottom centre, while the map shows aircraft positions and signal quality. These displays answer different questions: where each aircraft is, how it is doing, and how the link is performing.

As the main aircraft moves farther away, adjust the relay position as needed. Keep watching the signal bars and maintain a clear physical path between the controller and relay. Include relay battery state in the same scan as the working aircraft's battery.

Start and supervise Smart Relay

Smart Relay automatically adjusts the relay aircraft's position as the main-aircraft-to-controller distance changes. In the demonstrated sequence, enabling it in relay mode starts automatic relay takeoff; the pilot then switches to main-aircraft mode and takes off.

  1. Select relay mode and enable Smart Relay.
  2. Observe the relay aircraft's automatic takeoff.
  3. Switch to main-aircraft mode and take off.
  4. Monitor the relay signal bars and take over manually if the signal becomes poor.

Return from farthest to nearest

Return the farthest main aircraft first, then recover relay aircraft in sequence. In a dual-relay network, the order is main aircraft, Relay Aircraft 2, then Relay Aircraft 1. This preserves the supporting communication path while the distant aircraft comes back.

In Smart Relay mode, initiating RTH on the main aircraft makes the relay follow it back and hover above the home point. The relay still needs enough battery to support that return. If the relay initiates its own RTH, Smart Relay disables automatically; monitor the main aircraft's signal closely at that point.

  1. Recover the farthest main aircraft first.
  2. In dual-relay mode, return Relay 2 before Relay 1.
  3. Monitor all battery levels throughout the recovery.
  4. Confirm each aircraft's return and landing before closing the operation.

Questions & answers

How do I put Matrice 5T into relay findable mode?

Press its power button three times in quick succession. The power indicators blink in sequence when findable mode is active.

How do I identify an aircraft during relay setup?

Press that aircraft’s power button once. Its icon in the app flashes brightly for three seconds; use that to verify its assigned role.

What is the return order for two relays?

Return the main aircraft first, then Relay Aircraft 2, then Relay Aircraft 1. The tutorial calls this the far-to-near principle.

What happens if the relay starts RTH during Smart Relay?

Smart Relay disables automatically. Monitor the main aircraft’s signal as the relay returns; plan sufficient relay battery for the complete operation.

Welcome to our tutorial video for DJI Matrice 5T

where we will introduce the multi-aircraft relay feature of the DJI Matrice 5T aircraft

Matrice 5T can serve as a relay aircraft to provide relay service for other Matrice 5T aircraft

This further extends the communication range for emergency searches across mountains and undulating terrain

and in urban areas where buildings block the signal

The following four relay topologies are supported

1.Single-Relay, Single-Controller

1 remote controller + 1 relay aircraft + 1 main aircraft

One pilot uses a single remote controller to switch control between the two aircraft

which is ideal for single-person operations across mountains and obstacles

2.Single-Relay, Dual-Controller

2 remote controllers + 1 relay aircraft + 1 main aircraft

Two pilots divide the work

one focuses on positioning the relay aircraft

while the other focuses on the main aircraft 's tasks

3.Single-Relay, Dual-Controller, Triple-Aircraft:

2 remote controllers + 1 relay aircraft + 2 main aircraft

One relay aircraft serves two main aircraft at the same time

which is ideal for searching for multiple targets simultaneously

4.Dual-Relay, Dual-Controller

2 remote controllers + 2 relay aircraft + 1 main aircraft

Two levels of relay pass the signal along for ultra-long-distance operations or scenarios with multiple obstructions

Make sure all devices are powered on and placed together near the remote controller

On the DJI Pilot 2 homepage

tap "Relay Network Setup" to enter the relay network setup and linking page

Select the usage scenario based on your operational needs

This video demonstrates Single-Relay, Dual-Controller, Triple-Aircraft mode

The setup process is identical for the other topologies

only the number of devices differs

The Main RC controls only the main aircraft

the Relay RC controls only the relay aircraft

and the Main & Relay RC can switch between controlling the main aircraft and the relay aircraft

Press the power button of each aircraft three times in quick succession

When the power indicators blink in sequence

the aircraft has entered findable mode

After entering the device search page

the remote controller continuously searches for nearby devices in findable mode

During scanning

detected devices are automatically assigned roles in the order in which they are found

You can drag the aircraft shown on the remote controller screen to change their roles

Press the power button of an aircraft once

and its icon in the app will blink brightly for 3 seconds

so you can confirm whether it is the relay aircraft or a main aircraft

On the second remote controller

tap "Relay Network Setup" on the DJI Pilot 2 homepage and join the network

Tap "Join Networking"

Once the screen shows the two aircraft icons

you can enter the camera view

If a network setup failure is prompted

follow the prompts to make the corresponding adjustments

Once networked

the App confirms "Linking Successful" and returns to the home screen after 2 seconds

After the network is set up

to exit the network

press and hold each aircraft's power button for 5 seconds to relink or restart network setup

Single-Relay, Single-Controller

When the Main & Relay RC controls the relay aircraft

the relay signal shows the signal from the remote controller to the relay aircraft and from the relay aircraft to the main aircraft

When the Main & Relay RC controls the main aircraft

the video transmission signal is the Composite Signal of the aircraft being operated

Single-Relay, Dual-Controller

On the Main RC

the video transmission signal is displayed as the Composite Signal

On the Relay RC

the signal simultaneously displays the link from the remote controller to the relay aircraft and from the relay aircraft to the main aircraft

Single-Relay, Dual-Controller, Triple-Aircraft

Each of the two remote controllers controls one main aircraft

and the Main & Relay RC can also control the relay aircraft

The Main RC can only control its main aircraft

and its video transmission signal is the Composite Signal of the aircraft being controlled

When the Main & Relay RC controls its main aircraft

the video transmission signal is the Composite Signal of the aircraft being controlled

When the Main & Relay RC controls the relay aircraft

the relay signal shows the signal from the remote controller to the relay aircraft and from the relay aircraft to the main aircraft

Dual-Relay, Dual-Controller

The Relay RC can control either relay aircraft individually

while the Main RC controls only the main aircraft

On the Main RC

the video transmission signal is the Composite Signal

and the overall signal shown is the weakest of the three link segments

When the Relay RC controls Relay Aircraft 1

the video transmission displays the signal from the Relay RC to Relay Aircraft 1

and from Relay Aircraft 1 to Relay Aircraft 2

When the Relay RC controls Relay Aircraft 2

the video transmission displays the signal from Relay Aircraft 1 to Relay Aircraft 2

and from Relay Aircraft 2 to the main aircraft

During operation

tap the main aircraft or relay aircraft icon at the bottom of the screen to switch control

The camera view and signal display switch accordingly

During flight

you can monitor the overall status in the following ways:

Press and hold the R3 button on the remote controller to open Relay Spilt Screen mode

and view the auxiliary video stream of the other aircraft

AR projection:

when the two aircraft are more than 500 meters apart

the relay aircraft and the main aircraft display each other's positions

Status sync:

the HMS information and battery levels of the relay aircraft and the main aircraft are displayed at the bottom center of the screen

The map displays the projected positions and signal quality of the relay aircraft and the main aircraft

As the main aircraft flies farther away

adjust the position of the relay aircraft as needed

Always monitor the signal bars to keep the signal stable

and make sure there are no physical obstructions between the remote controller and the relay aircraft

When Smart Relay is enabled

the relay aircraft automatically adjusts its position as the distance between the main aircraft and the remote controller changes

to maintain the optimal relay link

In relay mode

enable Smart Relay and the relay aircraft will take off automatically

Then switch to main aircraft mode and take off

Keep monitoring the signal bars of the relay aircraft

If the signal becomes poor

take over manually

Follow the far-to-near principle for RTH

return the farthest main aircraft first

and then return the relay aircraft in sequence

In the Dual-Relay, Dual-Controller scenario

after the main aircraft returns

return Relay Aircraft 2 and then Relay Aircraft 1

from far to near

to prevent the link from disconnecting early

Note: In Smart Relay mode

when the main aircraft initiates RTH

the relay aircraft follows it back and hovers above the Home Point

Make sure the relay aircraft has sufficient battery power during operation

If the relay aircraft initiates RTH

Smart Relay will be disabled automatically

In this case

pay extra attention to the signal strength of the main aircraft to avoid losing the signal
