so my reciever is sticking out the back and seems thin. What to do to make it strong and not stick out the back also there's a disc that came with my rtf arris x220 v2. The disc is for my radio link at9s don't know what it's for. Also how do I set my drone up on betaflight. Need to do my throttle limits and do the failsafes so I don't have a fly away and much more. Need someone with FaceTime possibly and an hour of their day to help a. Either out before I wreck this thing lol
