Frequently Asked Questions - XRotor X8 Hobbywing

What is the recommended battery for the Hobbywing XRotor X8?

A 6S LiPo battery with 5000mAh capacity is recommended. Ensure the battery has a continuous discharge rating of at least 60A.

How do I calibrate the ESCs?

Connect the ESCs to the flight controller, power on with full throttle, wait for beeps, then lower throttle to zero. Follow your flight controller's calibration procedure.

What is the maximum payload capacity?

The XRotor X8 can carry up to 1.5 kg payload, including camera and gimbal.

How do I troubleshoot motor not spinning?

Check motor connections, ESC power, and signal wires. Ensure the flight controller is armed. If using a transmitter, verify throttle channel calibration.

What maintenance is required?

Regularly clean motors and frame, check for loose screws, and inspect propellers for damage. Lubricate motor bearings every 10 flight hours.

Can I use 4S battery instead of 6S?

It is not recommended. The system is designed for 6S. Using 4S may result in insufficient power and reduced performance.

What is the flight time with a 5000mAh battery?

Flight time is approximately 15-20 minutes without payload. With a 1kg payload, expect 10-12 minutes.

How to update the firmware?

Download the latest firmware from the Hobbywing website. Connect the ESC programming box to the ESC and use the software to update.

What do the warning tones mean?

A continuous beep indicates over-current. Intermittent beeps indicate low voltage. A double beep every second indicates ESC initialization error. Refer to the manual for details.

Where can I purchase spare parts?

Spare parts are available from authorized Hobbywing dealers and online stores. Common parts include motor sets, propellers, and ESC units.

Introduction

The XB brushless power system is a power system capable of carrying a load of 5–7kg (per rotor) for agricultural drones. It can provide the thrust of up to 15kg and match 30/35mm carbon fiber tube arms. It's waterproof an dustproof to IPX6 standard and resistant to rainwater, pesticides, salt spray, sand, dust, mud, sandy soil, high temperature and impact. It also features the algorithm used for optimizing the FOC ESC & Motor system and making the system more balanced, multiple protections like power-on self detection, power-on abnormal voltage, over-current and motor lock-up, and the real-time data output function.

Attentions

• Always keep your drone away from crowd, high-voltage power lines and obstacles, fly your drone in accordance with relevant safety regulations.

- Never get close to the high-speed rotating propeller & motor, otherwise you may get hurt - Check if all the parts are in good condition before use. If there exists any damaged part, please contact the factory for replacement.

- Check if any screw for connecting the parts is loose and the motors are horizontal before each flight.

- The bore diameter of the arm for the XB power system is 40mm. - You can change the light color of the LED set. In that case, you need to disassemble the light cover and slide the DIP switches accordingly.

- You can rinse the motor with fresh water after each flight to keep it clean.

Composition of the Power System

- Tube Adapter x 1 (from 35mm to 30mm)

Installation of the Power System Advanced Paramet

- The whole power system has been assembled before leaving the factory, it's ready-to-use and you can directly mount it on your agricultural drone as per the rotation direction (CW/C.W) marked on the motor.

- The (Black/Red/White) tri-color cable is for outputting data & updating ESC firmware, the (White/Black) bi-color cable is the throttle signal cable, and the yellow wire is the RPM signal output wire.

- The data signal wire is for outputting throttle input, throttle output, motor RPM, input current, output current, input voltage, capacitor temperature, MOS temperature, and etc. - The throttle range of the ESC is fixed at 1100–1940μs.

Explanations for Protections

• Start-up Protection

The ESC will shut down the motor if it fails to start the motor normally within 2 seconds by increasing the throttle input. In this case, you need to move the throttle stick back to the bottom position and restart the motor. (Possible causes of this problem: poor connection/disconnection between the ESC and motor wires, propellers are blocked, and etc.)

• Motor Lock-up Protection:

The ESC will cut off its output to the motor immediately and won't try to restart the motor when it detects the motor is locked up. In this condition, you need to pull the throttle stick to the bottom position first and then push it upward to clear the error and restart the ESC to resume the output.

• Over-current Protection: The ESC will cut off its output immediately when the peak current gets close to 300A. It only restarts after you power it off and then back on.

- Throttle Signal Loss Protection: when the ESC detects loss of signal for over 0.25 second, it will cut off the output immediately to avoid an even greater loss which may be caused by the continuous high-speed rotation of propellers. The ESC will resume the corresponding output after normal signals are received.

Troubleshooting & Warning Tones

		Possible CauseWarning ToneTrouble	Solution
The ESC was unable to start the motor.	“BBB...” a single beep that repeats rapidly.	The throttle stick wasn't moved to the bottom position.	Move the throttle stick to the bottom position.
The ESC was unable to start the motor.	“B, B, B...” a single beep that repeats (the time interval is 1 second).	There was no throttle signal output from the TH channel on the receiver.	Check if the transmitter & receiver are well bound, check if the throttle control cable has been properly plugged into the Th channel.
The power-on voltage was 18V.	“BB, BB...” a double beep that repeats (the time interval is 1 second).	The battery voltage was too low.	Change a suitable and fully charged battery.
The power-on voltage was above 55V.	“BBB, BBB...” a triple beep that repeats (the time interval is 1 second).	The battery voltage was too high.	Change a suitable and fully charged battery.

1. How to Change the Light Colo

Unscrew the two M3*B screws for fastening the light cover with a screw driver, slide the DIP switches accordingly (as shown below) to change the light color (it's Green by default), mount the cover back after setting.

DIP Switch 1	DIP Switch 2	DIP Switch 3	Color of the LED
ON	ON	ON	White
ON	OFF	ON	Light Blue
ON	ON	OFF	Purple
ON	OFF	OFF	Blue
OFF	ON	ON	Yellow
OFF	OFF	ON	Green
OFF	ON	OFF	Red
OFF	OFF	OFF	LED Disabled

1. How to Replace a Propeller

- Unscrew the two M6 *22 screws for fastening the blades with a screw driver and change the blade(s). If you also want to change the propeller adapter, then you need to unscrew the four M3*10 screws for fixing the adapter with another screw driver and change the whole set of propeller.

- When mounting the propeller, you need to mount the bottom cover (of the propeller adapter) on the motor first, then blades, spacers and the top cover (of the propeller adapter), and then fix them with screws. Please note that the blades can rotate freely after fastening them with M6 screws, and ensure that you will also apply some glue to the screws after fastening the propeller adapter to the motor with M3 screws.
