My drone crashed and I had to replace the outershell. During the repairs I noticed that some of the LED lights were damaged during the crash. But I did not think that they were critical to the flight operations. After replacing the Shell I reassembled everything put in a fully charged battery and prepared for the first test flight. The initial power on as normal the beeps the power on self test lights but then it goes dark there's no more lights there's no flight controls. Any thoughts?
