I keep seeing references that 1.4 is one of the better firmware versions out there for the Inspire. No speed limiting and yaw sensitivity was pretty decent. As a Pro owner, it has gotten confusing. They're not released on the same date, aren't numbered the same yet folks keep referencing firmware as 1.5 or 1.6.... For the Pro, which is the best performing firmware? Smooth controls are very important...I went back to 188.8.131.52 and flew it today.....very jittery and won't even fly in a straight line. I did an advanced IMU calib and used some of the gain/yaw settings seen here and on Facebook groups but it's terrible. Advice?
