POS value (lat/lon) drifting a lot, and crazy synthetic airspeed values

Looking at the OSD footage from the good and bad flights, I notice that shortly after launch when I see the “EKF3 IMU0 yaw aligned” message, the heading jumps by only 3 degrees in the good flight, and in the bad flight it jumps by about 70 degrees.

Not sure if its related or not but I had a crash which destroyed my plane where I lost control and my YAW jumps to crazy value after "“EKF3 IMU0 yaw aligned” message.

Here is my thread: EKF3 Yaw alignment on V4.4 dev brought my plane down
