Hi all.
I am building new quad-frame with M4 board+BLDC expansion board. After all wires was correctly connected and firmware was flashed i started tests. One motor+Kiss ESC 30a cant arm and spin. I tried to connect this motor in other ESC ports - it doe snot arm in any port. Although servo tester and receiver(when i connect wire from esc directly to PWM output) spins this motor.
What is wrong?
