Hi there. I just bought my Mavic Pro and after my third flight I had a crash. I didn’t see the electrical wires and the drone crashed fr 50 meters. Luckily it seemed to have only propellers. But when I replaced the propellers I gave it a try and the front propeller fly out and it didn’t take off. Then I check again and it seems that there is a different sound when I turn the motor. Any ideas? Hope replacing the motor will be enough. Here is the video of it
