• There is a problem with the battery itself, such as frequent use of fast charging to input power, which leads to short battery life and heat generation
  

2Control board device short circuit

• The short circuit of the control board is due to the damage of the mechanical circuit The reason is that there has been a collision, the battery output is too high, the circuit board is overheated and short circuited, and the software optimization has problems that cannot be controlled
  

3Free fall

• There are two cases of free fall in the air One is free fall with complete loss of power The main factor causing this situation is that the battery is deadThere is also a powered free fall, which happens a little more on quadrotors The reason is that when a quadrotor drone cannot provide enough power at one corner, the quadrotor will not be able to maintain balance and crash
