Phantom 3 gyroscope

[Red rooster]

Went fly my Phantom 3 Standard this evening, everything appeared fine, recalibrated the compass and updated the home point etc but then when I went to start the motors it refused and I got a message saying " Gyroscope bias value to large" What should I do now?

Thanks

Sounds to me like you need an IMU calibration.
Also, once you have a good compass calibration in a safe (not magnetically influenced) spot, there is no need to keep doing one.

What is an IMU calibration and how do I go about it? Thanks

Here are a couple of hundred posts about IMU calibrations if you want some background:
Search Results for Query: Imu calibration | DJI Phantom Drone Forum

Here's the first video that came up in Google:

If the IMU doesn't complete and/or you see bad data (accelerometer/gyro values) on the sensor screen, it may be stuck and need a slap or something similar.
