The quadcopter is increasingly popular in recent years, here, we have listed several representative problems of it. Before or after you buy one, you can check some annoying problems of it at here, we provided a perfect solution for you.

Q: Why even though all blades spin, the quadcopter still cannot flip/rotate/take off?

1. Battery power is insufficient, recharge the battery.

2. Check whether the blades are installed correctly.

Q: Why one of the blades does not spin?

1. Check the tightness of the blades.

2. Remove the blade that does not spin to see if the motor is working properly.

3. If the motor does not work, check whether the motor gear is connected properly.

4. Remove the body shell, check if the motor cable is connected to the mainboard appropriately.

Q: How to judge the steering of a motor?

1. Usually, motor with red and blue wires is usually a forward motor, while the reversed motor presents black and white wires; Diagonal direction motors have the same steering, adjacent motors have opposite steering.

2. On the motor surface sometimes you can find CW or CCW. CW stands for forward motor, while CCW refers to reversed motor.
