I am making a quad plane with wingspan of 1.6 meter with maximum takeoff weight of 12Kg, running Arduplane 4.0.9 firmware . Since I am new to arduplane, I dont have any practical knowledge in quadplane tuning. Can anyone please suggest a procedure of method to tune it?
The wiki and autotune
Are you sure about your 12kg target? It seems a lot for a 1.6m wingspan plane.
