Hi
I'm not new to flying multi rotors but I'm a total beginner with my new KingKong 260 with a CC3D.
I've installed LibrePilot, calibrated the transmitter (Taranis) but I can't make it fly, it won't arm.
I keep having the System Health output in red, saying I'm in failsafe mode. I don't know how to get rid of it and start flying!
Can anybody help?
