SectorDrone,
Any firmware update should be considered "aircraft maintenance" and you're hearing a concensus of post-maintenance experiences.
It's always your choice as to your post-maintence setup, pre-flight checklist procedures, and post-maintenance test flight.
Firmware 1.1.9 was 84,938KB in size and did not contain today's necessary SDK firmware additions. (1.1.8 is about the same file size)
Firmware 1.2.8 was considerably larger at 93,683KB, introducing numerous SDK additions.
This update led to numerous issues and the consensus of the majority of users was that IMU and Compass Calibrations
were necessary after this update due to possible sensor data corruption.
Firmware 1.3.20 is similar in size at 93,630KB and introduced roll-back capabilities and also include the SDK revisions.
Firmware 1.4.10 does not include the RC firmware so its size is smaller at 64,547KB but updates ESC and MC components.
So regardless of your decision for IMU and Compass calibration, after this update you should prepare yourself to fly a very conservative
"post-maintenance" check flight, keeping line of sight, prepared for the possibility of erradic flight.
You should be prepared for emergency procedures and if you P3 is solid as a rock, then consider yourself lucky; if it flys crazy, then you'll be prepared to recover and will have real grounds to perform the calibrations.
