Hi guys, I'm building my first quadcopter with Arducopter 2.6, a Happymodel U580 frame with retracting landing gear. I had the motors turning with a Turnigy X9 9ch transmitter, but couldn't get more than two flight modes with it because of outdated firmware. So I just got a FrSky Taranis X9D plus with an X8R receiver. I have the receiver bound to my transmitter and it shows up on Mission Planner in the set up portion, but for some reason the motors won't turn and it doesn't want to callibrate the escs with this unit. Can anybody help me understand what the heck is going on? I hope to get it flying before I die of old age.
