9 out of 10 flights I get a "can't take off"  error. Says IMU altitude exception.      If I wait a couple minutes and lift the Mavik up it clears and I can take off.  However with in a few minutes the displayed Altitude is way off!    I tried re-cal and no change.  Latest firmware no crashes only about 30 flights.  Is this something I can fix or must it go back?  Phil

Hi, thanks for reaching DJI Forum. We do apologize if you are having issues with your DJI Mavic Pro. May we ask what is the brand or make of the mobile device where you downloaded the app?  Also, what is the firmware of your aircraft? Thank you.

Have you tried to calibrate the IMU? Or try to refresh the firmware.

Had a similar IMU Error after the latest Firmware update
Got great advise from the forum.
Had to recalibrate the IMU. Just make sure that the surface is perfectly level.
After that it was back to IMU normal.

Thx 4 reply. Mine has done it since day 1, before and after updates and re cal.

DJI Mavic Pro - IMU Calibration

How do I get an RMA to get this fixed?  Have re-caled 5-6 times. Still getting IMU errors with altitude, baro. I can get the error to clear however after a few minutes of flying the altitute reading is way off. For example 100 feet in the air and alitute reads -7 feet. Need an RMA
