Hey guys--
I just finished my first ever quadcopter build, and am having some esc trouble. I am using the Emax Simonk 12a escs that I got in a kit off of amazon. I decided to use Libre Pilot software on my drone's CC3D onboard computer. I clicked on the Libre Pilot software install wizard, and everything was going fine until the esc calibration phase. I did the first step (the one that involves checking boxes and plugging and unplugging the lipo), and then on the step after that, everything went haywire. I replugged my lipo battery in, and pressed the start button (this is on the step where you find where the neutral point is for your motor) and started slowly moving the dial up. Immediately, my esc started smoking. I quickly hit stop, but it was too late -- parts of the circuit board were melted and the esc was obviously ruined. I was surprised, and figured that I must have just recieved a faulty esc in my kit. So, I went online and ordered another of the same esc off of amazon for $9. I soldered it into my build nicely, and got to the same point in the setup wizard, and the motor for the new esc started up slowly. Then, the esc made a small popping noise and will now no longer work. (I should add that I progressed onto the steps for the calibration of the other four motors' escs, and they worked fine.)
Am I doing something wrong, or did I just have the incredibly bad luck to get two faulty escs? Or is there a compatibilitiy issue? Thanks, help is appreciated greatly.
