Mavik Pro went totally out of control

[Grapecrusher]

Hi everyone,

Am a complete newbie to drone flying but had my Mavik Pro in Beginner Mode, GPS and IMU were ok to go and when I launched it lifted off ok to around 2 ft then began spinning and suddenly shot off and crashed. This happened after I updated the firmware in the middle of a vineyard.....hence Grapecrusher....It had been sitting in the sun while I upgraded so not sure if this caused the problem. However, nothing showed on the controller and the updated completed without problem. The drone crashed this way 3 times and although no damage . done I am a little concerned about trying again. Any ideas would be very welcome.

Hey thanks,

I will check my logs via ITunes tomorrow and post as I don’t think I will have a clue how to read the info. Thanks again.

I am just assuming here but the spinning out of control, appear to be the propellers not properly installed. But the logs will tell the truth.

The props are all fine. They turn quite freely on pre-flight check. The Mavic lifts off straight then just starts spinning

First of all I would never do an update why it was sitting out in the sun.

Yes looking at the top of the motors for the white ring and the same mark on the prop would be a good start . There are two that spin CW and two that spin CCW . Two props have the ring and two don’t . [emoji41]

It wont lift off if props are on incorrectly. Which is nigh on impossible (put props on wrong) to do anyway.

Well, I certainly won’t make that mistake again!

All props are on the correct configuration. Thanks.

I did my update using my wifi in my house . Using your cellphone package will eat up the data in a hurry

When your drone is turned on and motors off have a look at your screen showing your compass and the two bar grafts that show interference . I would do this at the launch site and see if the drone is unhappy about something

Just a note to yourself. Whenever you do a firmware update go through all your settings and make sure nothing is changed. And you should do a Compass and a IMU calibration just to be safe.

Hi, just had a look at the flight logs/reports and it shows compass errors then speed errors. As I was close to the vineyards perhaps there were metal posts that I didn’t see and that was the cause even though I didn’t have magnetic interference on the controller? I shall try tomorrow in a different area!

Ok. Thanks, will double check everything.

You’ll probably find it is the compass interference. When you try another location, make sure the icon on the radar screen matches the exact direction your drone is pointed. Turn your drone and make sure the orientation stays the same on the radar. If it’s pointing another direction, find another spot and check again.

also, both the AC and the RC need to be rebooted first thing after an update, did you remember to do that?

I think you nailed it.....I didn’t re-set the RC or AC after upgrade.....dummies that I am. And have since discovered that all the supports in the vineyard are metal!!!. Thanks for your help.

Hi there,

Found one of the flight records and it shows compass errors. If it is in beginner mode and I did not get a notification that I was in a magnetic area, would this be because after updating my firmware I forgot to re-boot both the RC and the AC?
