Hi guys I'm facing a problem with Emax 4in1 esc 25Amp.
First motor has throttle reversed i.e. when i put throttle to max then it gives starting beeps and for other motors it is normal i.e. they give starting sound with throttle down position
I read manual and Googled but couldn't get any solution!!
Any solution for this problem?

Have you calibrated the escs.... looks like a calibration issue

Hi Antariksh. Let me know first that you are using this esc for a quad. if so then the esc output pins for this esc are actually reversed. so it depends on which controller you are using. the orientation of the output wires is little bit difficult to identify. so its better  to connect individual esc output to a motor and check out which wire goes to which  motor. then you can connect that particular output to the respective controller pin. its not a difficult job, hardly it ll take 10 mins.

Found problem with FC it's output pins are not working.
Some repairment required

Well n Good
