i assembled my arducopter hexa x (bought at 3drobotics).
Mounted the APM 2.5 facing forward and not upside down.
Now i realize that leaning the copter to the right shows leaning to the left in the Mission Planner and vice versa.
Whereas leaning forward and backward works as expected.
Is this a hardware or a software issue?
Please help me to fix this!
Thanks in advance
