IMU Warm Up - P3A Firmware 1.3

[tundrastruck]

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.

"As cold as possible " lol

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!
