OK,
Yesterday, I decided to perform another IMU, VPS, Gimbal, and Compass calibration on my MA, and take it out for another test flight.
The IMU calibration was performed on a COMPLETELY LEVEL (both X and Y axis verified level with high-end bubble level) platform that I adjusted to perfect flat, to make sure the IMU calibration was perfect.
After calibrations were complete, I took it out to a completely empty football field, away from any interference sources such as power lines, cell / Wi-Fi antennas, and such. Weather conditions were sunny at 30c, with 0 KM/h wind.
The attached logs were of my first flight, including the video screen capture of the app.
Upon take-off, not only did I experience the now-known yaw twitch to the left, but afterwards, during the precision takeoff sequence, it CONTINUED to yaw left, then once the precision takeoff finished, started to yaw right!
In the video clip it shows me putting it in Sport mode, so I could bring it low to me and close by, to examine how well the IMU calibration worked in terms of the drone hovering level. It hovered completely level, and after the yaw glitches, seemed to be rock solid, but later on in the flight also began having yaw drift.
If @Brantel or @JJBSpark could look at these logs, would be very appreciative!
