5.        Flight Controller Data Analysis Series Tutorials – Stopping Motors by Conducting the Combination Stick Command (CSC)

CSC refers to pushing the control sticks on the remote controller to the bottom inner or outer inner corners to start the motors, as shown in figure 5.1.

Methods for stopping motors in emergencies may vary depending on the aircraft models. Methods for stopping major DJI drones in emergencies are listed below.

*The preceding methods for stopping motors in emergency situations only apply to those drones with the firmware versions when this passage is written (2017.09.27) and are subject to the User Manuals and release notes of the specified products if there are any updates

It is risky to stop motors when the drone is flying in the air, as the drone will directly drop down. Before flying the drone, make sure that you are familiar with the method for stopping motors when the drone is flying to avoid conducting the method by mistake. If the sticks are pushed to stop motors mid-flight, we can find the following in the data: the stick output curves peak, the height curve suddenly decreases considerably, the accelerometer curves change significantly (the drone drops to the ground), and the motor start flag switches to 0.

In figure 5.2, the drone becomes powerless and drops from the air at 683s.

The motor output stops at 683s, as shown in figure 5.3.

Figure 5.4


In figure 5.4, it can be found that the sticks are pushed to the bottom inner corners according to the curves for the sticks’ output at 683s.
