I purchased a refurbished solo from BB last year. Recently I purchased a 2nd that came with extra batteries and gimbel, now I have 2 solo drones. Wanted to get some opinions on should I keep it or sell it. It has some scratches on the motors, but flys great. The money would go to a Gopro 4, but should I keep it as a backup? Thanks. Also, how much could I get for it?
