I'm planning on buying one of the signal increasing boosters to be put on my controller, and of course that will void the warranty. So would it work if I bought another controller and kept it in stock condition if I ever need to send in my drone to be repaired or anything of that nature? I've read that only one controller is made to be paired with the drone but there is a linking button on the drone itself, so couldn't you essentially have 2 controllers for one drone?
