For gesture mode, palm take off and flying without connecting to RC or smartphone. Does the compass issue still affect such users ? How can they avoid compass error issue or they are immune ?

Thanks

Yes, it still affects gesture mode users. No it gives no warning. Yes, it will fly away.

You are now advised to have device connected to spark when using gesture or palm control.

Tell DJI that. They bill this is a selfie drone, no connection required.

If they are going to sell that, then it shouldnt become dangerous in that mode.

All drones are dangerous in the wrong hands, safety should be paramount always, failsafe's and redundancy are never a bad thing to use when you can.

2 minutes of a 12-14 minute flight is a considerable amount of time.

Well it will take you almost 1 minute to warm up IMU and get gps lock, it's your aircraft if you feel you don't need to check that's entirely up to you, there are many here who haven't checked before they fly and much of those lost spark could have been avoided.

yes , but that sill don't explain that DJI sell this as a first time drone and for some reason DJI did't do this check list , only you , a normal spark user like me and him.. So if a NORMAL person "stick" to what see in the ad's and read in the manual he is kind of ... on the lost position . Even if he will NOT do any calibrations if not needed , he still can lost his drone from no reason KNOWN and will don't have a AC ( far flyaway or water) AND no log on the device (if palm launch). Potential user is not in the way of KNOWING THIS .

I didn't see anywhere advertised that this is a first time drone, also if you pay €500 for something then respect it, your are asked first before you fly to read the manual, in your manual it clearly tells you to fly in suitable environments not close to buildings not over water. It tells you clearly not to calibrate compass unless prompted. It has beginner mode for those who have never flown before and it has age limit of 16, there comes a time in everyone's life when we must be responsible for what we do and how we do it, I don't think dji should be or need to be responsible for adults wanting to use their drones.

We don't need to make excuses for those who have not prepared properly and gone out and crashed their drones, let people take ownership of their own mistakes.

For those who have lost drones because of malfunction then this is dji's responsibility.

Yes you are right , but still of the Subject i am all about.  Even if you do all this  as you stated , in case of palm  launch  you ask for problems  that DJI dont talk about . I think in manual 1.2 or 1.4 there is a line where "it is advised to be connected to a controller in palm launch"  but in the  advert you see man on a bridge lunching from his palm , now in real life this can end up in a fatal crash for spark in  good amount of cases . we have reports that after palm launch it drifts etc. and than no care refresh for you . I don't know why you try on every subject to act like DJI personel stating that it was a user error etc. Its your action's, not my interest but remember there are always two sides of a coin.

I couldn't agree with you more. But that is the purpose of marketing, to show you that life is heaven...
I also agree with your example, but DJI does not lie, you can really palm launch like in the promo video, but it is advisable to connect to a phone. So, I don't think there is anything to blame DJI here.

I once purchased a Mac Pro laptop , because I seen in advertising that it could do some great video and photography editing.
When I received my Mac Pro, I soon realised that in order to make beautiful videos and photographs I would need to read all I could practice as much as I could before I could even get close to the to what the guy in the video was producing , this is the way advertising works.

I don't think every malfunction and crash is user error and I have never said that, just the same with all technology products there are always some which are defective and these are the responsibility of the company's to put right

fair enough . I also think that most of spark crashes are operator flout . bat not all.

no warm up time for spark...  IMUs and compass dont seem to want it or need it, i guess they aren't thermally referenced like much higher end DJi drones.  the only waiting time is GPS lock and more often you play with the spark and use it, the less time it takes waiting for the GPS locks..  usually 30 seconds at most...

its up to your own discretion, this is just a helpful tip, take it or leave it. its worth it for a $500 drone in my opinion.

In my experience it goes faster than two minutes.  If it does take a while, that's an indicator that something is not right, and that the pilot should evaluate the circumstances carefully.

When I was just starting out I tried to fly a P3S with compass errors and gps warnings.  OMG!  Most stressful five minutes of my flight life!  I'll never ignore warnings again.

By "prompted to" do you mean a warning in the AC status bar in DJI Go 4? Or just flashing red/yellow status lights? I think I might have been calibrating too often, but have had no bad effects as yet.

The most common warning you will see is move aircraft or calibrate compass, just move aircraft, if you get a warning telling you to calibrate compass it will pop up on the warning screen while Imu is warming, you will see a box saying calibrate in white if this changes to red/blue then you should calibrate, if it's white then your fine.

When I took the Spark to Crete, the Villa I was in had big aircon units and these caused magnetic issues, I also did get asked to recalibrate compass, which I did fine.

I did the IMU before I went, but wouldn't have bothered as I just read to do it, but feel now with other advice I shouldn't have.

You need to give more information, where are you taking off from, where did you calibrate your aircraft.
The warning you are receiving is to move aircraft and start your launch procedure again.

I didn't realise this.  Because the Go 4 app starts with the status panel open where the compass has a [calibrate] option it sort of invites you to re-calibrate every flight.

In the future I'll only respond to warnings on the panel
