Drone FAQ Analysis and Solutions

Symptom

Possible reason

solutions

The motor cannot be started after power-on, no sound

Poor contact of power connector

Reinsert the connector or replace the connector

The motor cannot be started after power-on, and the “哔-哔-, 哔-哔-, 哔-哔-” warning tone is issued (the interval between every two sounds is 1 second)

Battery pack voltage is abnormal

Check battery pack voltage

The motor cannot be started after power-on, and a “哔-, 哔-, 哔-” warning tone is issued (the interval between each sound is 2 seconds)

Receiver throttle channel without throttle signal output

Check if the cooperation between the transmitter and the receiver is normal, and whether the throttle control channel wiring is tight.

After the power is turned on, the motor can't start, and the "哔, 哔, 哔, 哔, 哔" sounds a single tone.

The throttle is not reset to zero or the throttle stroke is set too small

Put the throttle stick to the lowest position;

Reset throttle stroke

After power-on, the motor will not start, and a “哔-哔-” beep will sound, then a “56712” special tone will sound.

Throttle channel "positive/reverse" error

Refer to the remote control manual to adjust the “positive/reverse” orientation of the throttle channel.

Motor reversal

Wire order error of ESC output line and motor line

Reverse any two of the three output lines

The motor rotates in the middle of the rotation

Throttle signal loss protection

Check if the cooperation between the remote control and the receiver is normal, and check if the throttle channel wiring is in good contact.

The battery voltage is insufficient and enters the low voltage protection state.

Recharge the battery

Poor wiring contact

Check if the battery pack plug is normal, the ESC output line and the motor cable connection are stable and reliable.

Random restart and working condition

Extremely strong electromagnetic interference in the environment

The normal function of the ESC is subject to strong electromagnetic waves. When this happens, please refer to the instruction manual, try to restart the power to start the normal working state; when the fault occurs repeatedly, the electromagnetic interference in the use environment is too strong, please use the product in other places.

The plane can't fly or flip together

The motor is turning backwards

The propeller is reversed

The ESC signal line and the flight control connection sequence are wrong.

Check the motor steering, the propeller front and back paddle installation, the correct connection sequence between the ESC signal line and the flight controller

Motor jitter does not turn

Poor contact between the motor and one of the ESC wiring

Check if the motor and ESC are soldered to the banana head, and the wire is loose.
