I bought a 60 A esc with a 4 A bec! http://www.hobbyking.com/hobbyking/store/__16892__Hobby_King_60A_ESC_4A_UBEC.html the only problem is... It don't work. I resoldered, tried different motors and batteries with it and it still doesn't work. it powers the receiver and servos but the motor doesn't respond. it tried setting the throttle end points but still no power to the motor. Anyone know what's wrong?
