Hi folks, does anyone has any explanation why when the AMP/IMU  board is static still the values of gx gy gz changes, should't they remain at zero. The intresting thing is that on CLI test mode I get…Continue

"Hi everyone, I really want to know If I wanted to supply power to my APM v1.4 through VIN pin using a 7.2v adaptor then what shoudl be the max current (amp) of the adaptor ?"

Hi folks, does anyone has any explanation why when the AMP/IMU  board is static still the values of gx gy gz changes, should't they remain at zero. The intresting thing is that on CLI test mode I get zero values for gx gy ang gz while on the flight tab they start vary. see below. Any Idea.?? See More
