Aircraft

The Agras T50 aircraft features an anti-torsion structure for reliable operations. Its integrated spraying system can be quickly transformed into a spreading configuration with a payload capacity of up to 50 kg. The aircraft is equipped with a phased array radar system and a binocular vision system, including downward and forward binocular vision, and forward and rear phased array radar. These systems provide 360-degree omnidirectional obstacle sensing for operational safety. The ultra HD FPV camera with a tiltable gimbal can automatically collect HD field images for local offline reconstruction, aiding in precise field planning. The Coaxial Dual Propeller structure generates a strong wind field, allowing pesticides to penetrate thick canopies for thorough spraying. The spraying system includes a Magnetic Drive Impeller Pump, Dual Atomized Sprinkler, Anti-Drip Centrifugal Valve, and solenoid valve for efficient and precise pesticide spraying, while also conserving liquid pesticide. The spraying system can be upgraded with two additional sprinklers to accommodate different operational scenarios.

Using the T50

Preparing the Intelligent Flight Battery

Only use official DJI flight batteries. Check the battery level before flying and charge according to the corresponding manual document.

Battery Model: BAX702-30000mAh-52.22V

Preparing the Aircraft

1. Unfold the M3 and M4 arms, and fasten the two arm locks. Avoid pinching fingers.
2. Unfold the M1 and M2 arms, and fasten the two arm locks. Avoid pinching fingers.
3. Unfold the propeller blades.
4. Insert the Intelligent Flight Battery into the aircraft until you hear a click.

- Ensure the battery is firmly inserted into the aircraft. Insert or remove the battery only when the aircraft is powered off.
- To remove the battery, press and hold the clamp and lift the battery up.
- Fold the M1 and M2 arms first, followed by the M3 and M4 arms. Failure to do so may damage the arms.

Getting Ready for Takeoff

1. Place the aircraft on open, flat ground with the rear of the aircraft facing toward you.
2. Ensure propellers are securely mounted, no foreign objects are in or on the motors and propellers, propeller blades and arms are unfolded, and arm locks are firmly fastened.
3. Ensure the spray tank and flight battery are firmly in place.
4. Power on the remote controller, ensure the DJI Agras app is open, and power on the aircraft. Tap Start in the home screen of the app to enter Operation View. Verify that GNSS signals are strong and the screen displays "Ready to GO (GNSS)" or "Ready to GO (RTK)". The aircraft cannot take off otherwise.

RTK positioning is recommended. In the app, navigate to Operation View, tap > RTK, and select a method for receiving RTK signals.

Calibrating the Flow Meter

Calibrate the flow meter in the following situations:

• When changing liquid payload with different viscosity.
• When the difference between the actual area and planned area exceeds 15% after the first operation.

Calibrating procedure:

A. Get Ready to Calibrate

1. Fill the spray tank with approximately 2 L of water.
2. Press the Spray button to start or stop spraying manually to exhaust air.

B. Calibrating the flow meter

1. In the app, navigate to Operation View, tap ∇>∇, then tap Calibration on the right of the flow meter calibration section.
2. Tap Start Calibration. Calibration will begin automatically and the result will be displayed in the app upon completion.

- After successful calibration, users can proceed with the operation.
- If calibration fails, tap the reminder to view and resolve the issue. Recalibrate afterwards and wait for successful calibration.

Flight

For automatic takeoff and operation, it is recommended to create a plan for a field and select an operation before takeoff. Refer to the "Starting Operations" section for details. For other scenarios, take off and land manually as follows.

Takeoff

Perform a Combination Stick Command (CSC) and push the throttle stick up to take off.

[Image description: Diagram showing the throttle stick on a remote controller being pushed upwards.]

Landing

Push the throttle stick down until the aircraft lands. Two methods are available to stop the motors after landing:

• Method 1: When the aircraft has landed, push and hold the throttle stick down. The motors will stop after three seconds.
• Method 2: When the aircraft has landed, push the throttle stick down, and perform the same CSC used to start the motors. Release both sticks once the motors have stopped.

[Image description: Diagrams illustrating Method 1 and Method 2 for stopping the motors after landing.]

- Spinning propellers are dangerous. Stay clear of spinning propellers and motors. Do not start motors in confined spaces or near people.
- Maintain control of the remote controller while motors are running.
- Do not stop motors mid-flight, as this will cause the aircraft to crash. Stop motors only in emergencies to minimize damage or injury.
- Method 1 is recommended for stopping motors. Use Method 2 with caution, as the aircraft may roll over if not completely grounded when using this method.
- Power off the aircraft before turning off the remote controller after landing.

Starting Operations

Users can perform aerial surveying of the operation area in the DJI Agras app and receive an HD map via offline reconstruction in the remote controller. Field planning and identification can be done on the HD map before route operation. The following steps use Crosshair and Route Mapping and Route Mode as examples.

1. Power on the remote controller and then the aircraft. Enter Operation View in the DJI Agras app.
2. Tap the Mode button in the upper left corner and select Route Mapping in the Mapping panel.
3. Tap ↓ on the bottom right of the screen and select Area Route or Boundary Route. Then tap in the middle of the right screen to select Crosshair in the Add Point list.
4. Drag the map and tap Add to add a point at the crosshairs. Tap to save.
5. Tap and move the slider to launch the aircraft. The aircraft will perform the mapping operation along the route and land automatically.
6. Wait for the app to complete reconstruction. The reconstruction result will be displayed on the original map.
7. Tap Identify Field, then tap an identified field to select it and adjust the boundary.
8. Tap the Mode button in the upper left corner and select Route in the Agriculture panel.
9. Tap > on the left and select a field from the field list.
10. Tap Edit to edit the field and set route parameters. Drag ↻ to adjust the flight direction of the route. Then save.
11. Tap ✓ to use the field. Set task parameters and tap ✓ to save.
12. Tap →, check the aircraft status and task settings, and move the slider to take off. The aircraft will perform the operation automatically.

- Take off only in open areas and set appropriate Connection Routing and RTH Altitude based on the operating environment.
- An operation can be paused by slightly moving the control stick. The aircraft will hover and record the breakpoint. The aircraft can then be controlled manually. Selecting the operation again will allow it to resume. The aircraft will automatically return to the breakpoint and resume the operation. Ensure aircraft safety when returning to a breakpoint.
- In Route and Fruit Tree Operation modes, the aircraft can circumvent obstacles. This feature is disabled by default and can be enabled in the app. If enabled and an obstacle is detected, the aircraft will slow down, circumvent the obstacle, and return to its original flight path.
- Users can configure the aircraft's action after completing an operation within the app.

More Operation Modes and Functions

Refer to the user manual for more information on A-B Route Operation, Manual Operation, and Fruit Tree modes, as well as functions like Connection Routing, Operation Resumption, and System Data Protection.
