    Hey All,

    Ever since I've updated to the new firmware my P3A seems to take a lot longer to warm-up. It takes like almost 2 minutes compared to before where I'd wait 30-60 secs. After the update I did an IMU Calibration.

    Anyone else have this issue with new firmware?

    Is another IMU calibration needed?

    Mine did the same thing after the update, 1-2 min.
    Today I set the P3P in front of a window air conditioner for 15 min and than recalibrated the IMU.
    It dropped the warmup to 30 sec.

    I'll have try it again I guess. I live in a cool climate so it's not overly too warm in the house. Didn't think it would affect the IMU that much.

    I believe that the IMU has to reach the temperature at which it was calibrated prior to reading ready to go. One time I calibrated the IMU on a hot afternoon, and had to wait a long time prior to the quad saying the IMU was warmed up. Since then, I've calibrated the IMU on cool mornings.

    Remember that it heats up during the firmware update. Let it at least cool before the calibration.

    cnynctry is totally right. It gets very hot during the update!
