hi, I have problems with my arducopter that mounts the APM tab 2.5. I have done step by step instructions contained in the site, but by controlling the RAW view of the sensors, known that, if I swing forward, back, left and right, the engines do not come all the same scheme. Thanks in advance to those who help me
