Can you tell me what exactly these signal plus (sticky kit) do ?!
because I crashed with door inside the house and on of that was came out from one of the legs, So I just push it back under propeller and put the hover`s leg back!!
A: It seems you are talking about the rectangle circuit board installed under two of the motors. This is an antenna and if it becomes loose during a crash, as long as the wire is attached it will still function correctly.
