Routine drone maintenance is second nature to me now. But every so often one comes in with a failure that makes no sense, where nothing I check explains what's going wrong, and I'm completely stumped. I take it apart and put it back together and it still won't behave, and I hate feeling that lost.
More people experience this than they realize.
You can handle routine drone maintenance, but the strange complex failures still stump you.
