i have apm 2.6 ,and i calibrated my esc s manually after automatic had failed , and when i connect all motors it seems only 1 and sometimes 2 , it seems to fail to calibrate ? what shell i do , serious problem…?
Hello, The most tried and true method i recommend is to advance the throttle to full with the quad not powered and with the props off, then plug the quad in. after the beeps lower the throttle and listen for the sequence of beeps to finalize and you should be calibrated at that point.
