I've got a quad copter built with Dji naza m lite and 30 amp esc and a sky fly transmitter. When i arm the motors one of them just turns on constantly and the other three motors turn on at different times when i throttle up. Can anyone help??
Is this with no props on? If so, it's quite normal. Once you get props on the controller knows where to put power to maintain a level attitude, without them, it will spool up one motor randomly and if that doesn't level it, keep upping the revs.
