Quadcopter motor test is one of the most crucial procedures in the entire quadcopter designing process.
It, therefore, requires utmost care if at all it is to be done to precision. This begs the questions; what do we require to test a quadcopter motor?
How is the testing process conducted? Come with me as I unravel the mystery on how to test your quadcopter motor accurately.

How to test quadcopter motors
I would like to draw your attention to the last requirement first. What is a mission planner? Before I answer that question, I would like to point out that there are two options when it comes to testing a quadcopter motor.
The first one involves following several steps as we will see later. However, the second one involves the use of this device, mission planner. It a device used to test the motor and any other part of the entire quadcopter without having to manually test them.
So, it is basically an automated gadget for testing parts of a quadcopter. You can see it on the image below.On the other hand, let’s take a look at the first and most preferred way of testing a quadcopter motor. This method involves the use of the other tools mentioned above. The first thing you need to do is ensure that you have no propellers on the quadcopter before you start the testing process.After that, you are required to ensure that the flight mode is set to stabilize and then turn the transmitter on. After turning the transmitter on, you are then supposed to connect the battery. This is a crucial step which needs to be done carefully in order to ensure that power supply is adequate.After you have done all that, you can now arm your copter. How do you do that? Well, to arm your copter you simply hold the throttle to the right and down while at the same time holding the rudder right for like five seconds.If you copter fails to arm, which implies that there might be an error, you should recheck your entire configuration. In fact, this implies that the Pre-Arm Safety Check has failed. In this case, the Pre-Arm ought to automatically go to Pre-Arm Check Page and then attempt to correct the error.If your arming was successful, you need to apply some reasonable amount of throttle and then take note of the direction to which each motor is spinning. The directions should match the specified frame type.
In case any motor spins to the wrong direction, you need to correct it. How do you correct that? All you need to do is simply interchange two out of the three motor to ESC power leads. Look at the frame types and the expected motor directions on the images below.
