Compass error - restart aircraft

[Rich UK]

Hello, I've got a few flights under my belt since getting my Phantom a few days ago and love it.

Today prior to flying I did the I'M and gimbal calibration and already I saw it made a huge difference in stability (unless it was just less windy?).

I then did a compass calibration and went to do an auto take off. It then gave me an error which I couldn't properly see as another screen kept popping up in front of it almost immediately. I think the message said 'compass has failed, please restart the aircraft'. It seemed to calibrate OK though which was odd. I may be wrong as to the exact wording of it but it was along those lines.

So I restarted it, don't think I calibrated again and all was fine, managed to auto take off and didn't experience anything weird. Do I need to worry about the error, is it likely to occur again in anyone's experience or shall I just carry on as normal and stop being paranoid?

Thanks,

Rich

Yes, error messages may appear from time to time. so it's suggested to lift off and hover a couple minutes to check if things appear ok. warm up the battery and then take off
Sure..flying any pricey drone, be cautious, be normal.. ha

I had something like that happen once. It's never happened again. It was on the second flight that I made with my P3P. I haven't changed a thing and it hasn't happened again. Mine was a compass failure.

No need to warm up the battery .... not even when flying in the UK ;-)

You'll do well to take off to about 6 to 10ft, check the controls (fwd, back, left, right, yaw) let it hover for 30secs. Have a quick check of you battery cells and that no errors have popped up ..... and away you go

Cool cheers guys, reassuring.

Yeah no, only in Canada? Hahaha

An occasional compass error is to be expected. They are finically little beasts but RHP's suggestion of hovering around briefly is a good one. Before you get too enthusiastic about recalibrating, read Ianwood's important article on this topic.

I always let it hover at my eye level for a few, just to be sure everything is rock steady, and to quickly check the MOD values/numbers.

Once it has been proven stable with no jitters or erratic movements, off we go...
Here's a quick list...
PFC, pre-flight checklist

• Phantom & R/C battery charged
• Tablet charged (reset or remove apps from memory)
• Propellers installed and tightened
• Remove gimbal lock
• Gimbal not obstructed (grass)
• Tablet volume & luminosity to MAX
• Tablet « Do Not Disturb » Mode
• Tablet to R/C cable attached
• Tablet Wifi & BT OFF R/C ON
• R/C in P-Mode
• Phantom ON
• Launch DJI Go app

Check values :

1. Compass status
2. IMU values (0, 1, 1400-1600)
3. Gain values
4. Max height
5. RTH height (depends on flight location)
6. R/C EXP & Gain (0,5-0,4-0,5)
7. VPS ON (if indoor flight)
8. Satellite status
9. Format SD card
10. Camera settings (LOG, video size, …)
11. Gimbal configuration (1, 2 or 3)
12. CHECK HOME POINT CHECK BATTERY STATUS (Cells)

Finally: Takeoff Hover 30 seconds & check stability

All systems are Go!! Hahaha
