After I tried and followed the instructions of the PAINESS360 video on how to calibrate the full ESC, but no sound comes out of the ESC / motor as the instructions are in the PAINLESS360 video. However after I try ESC calibras ESC-by-ESC manual like the one in video, it all works. But my two motors are very hard when spinning, unlike the other two motors are soft when spinning, I try to repeat again, but still the same. Is there something wrong.??
But I do not really care, and I keep going. I tried to ARMED, and after ARMED, and I tried to raise the throttle slowly, but all the motors do not want to spin … what should i do. ??
