Today tried to fly my X4 setup frame with U8 motor and 29" props with GPS mode
It was not stable ,fortunately could land successfully
During fly got warning
Tilt angle error " adjust the center of gravity to the geometric center of the aircraft
Center of gravity checked ,calibrated as well , ESC calibrated as well ,using X-Rotor 40A ESC
Gains by default 100
Any advises ?
