I had crash last week due to a silly error in setting a height for an automission. The Cube Black/Arducopter on a Kore carrier board detected the crash and disarmed the motors within 2 seconds after hitting the tree. Thanks to some help from friends, the drone was retrieved and it looked as though the only problem was broken propellers. I replaced the props and tried to fly it today. She will arm, but only three motors spin. I changed the motor and the ESC. I can’t seem to calibrate the new ESC, and it does not spin up during the motor test. Could I have burned up something on the Kore board?
Have you used the same amp esc and same motor which you used earlier before crash ? If yes, then try do perform the callibration properly.
