I was flying a mission this morning and the Mavic Pro started to drift away from the flight path towards the southeast. I hit the return to home and it returned to home successfully. I started the mission again, and the Mavic Pro started to drift away from the flight path in the same place. I hit RTH and it returned to home successfully. What’s going on?
Since I posted that earlier today, I calibrated the Mavic Pro using the Assistant 2, and just had a successful mission.
Hi @BobO,
I’m happy to hear that you had a successful mission and am sorry we didn’t get to your original post sooner to assist.
In general, we recommend calibrating and updating everything as a first step before flying for the first time and even routinely to make sure things continue to run like a well-oiled machine. 
Cheers,
Christina
