Hello guys. I am building an octocopter (Tarot X8). When it comes to the ESC Calibration part something weird is happening. That playing an constant beeps, same sound. However I change throttle to max/min, no any response. Here APM controller is used. When I connect it to power only 3 out of 8 propellers are making some a little bit movement, but other 5 propellers are not. I am seeking some help&advices…
btw, whenever the power is connected neither APM or arduino doesn’t have any blinking lights.
