I looked through the comments but didn't find my exact situation. I have the FlySky SM 600 controller. What do I need to do in order to get this to work with FPV Freerider? It almost works...I get throttle and pitch, but no yaw or roll, no matter what I do. I tried everything that I could think of last night, spent a good 3 hours playing around with it. Any help would be appreciated
