I'm new to racing quads. I have 3 quads, and use a Teranis plus for my radio. I have had so many problems with them working, You name it, it has happen to me. a drone will work one day the next it won't. I think I need to take the radio to factory reset and download software again on my radio and quads. Too many have tried to help. The drones don't work. I am getting so frustrated. Whoever reads this; you may be my last hope. I may have to sell out, to keep my sanity. What was to be a hobby and a way to meet new friends. Has turned to a pain in the ass. Especially when I show up and my drones don't work. So, if anyone has advice, I'm listening.
