Problem summary: MP shows 'prearm: RC ROLL not configured’
Problem description: One of my Pixhawk2.1 is having a strange issue. When i load arducopter3.4, it is able to arm completely fine. However, when I load beta AC3.5 rc11, the mission planner HUD shows ‘prearm: RC ROLL not configured’ whenever I try to arm. I have tried to calibrate RC a few times but it still shows the error.
Really appreciate anyone to help with this issue.
