Hi everyone, just wanted to know if anyone else has had this issue. Just opened a brand new p4 not even a single flight. Just turned it on to check it out and I keep hearing a repeating click noise. When I hold up the drone to my ear it sounds as its coming from the sensors from u dear the drone that face the ground like maybe the sonar or something. It's still brand new and wondering if this is normal or should I exchange it. Any help would be greatly appreciated. Keep well.
