Hi guys,
Are you curious if the manufacturing date relate to the mal-functioned Sparks?

If your Spark is not working as it is supposed to be, check the manufacture date here and see if there is any common?

i am not currently part of these fall statistics but i'll contribute data for my current spark:

decoded date: Friday, June, 23rd 2017

location of purchase: Amazon (DJi offical store listed through amazon, not sold by amazon)

date purchase: July 31st

date activated: August 2nd

FW of aircraft on receive: 0.400

Your Spark (Minexxxxxxx) was manufactured on Saturday, June, 24th 2017

Mine fell out from 91 mts high

Never had a problem with my Spark. Manufactured Friday, June 23rd 2017

Hey everyone, my spark was manufactured on Thursday, July, 6th 20th 2017. I have had no problems so far but I have not tried drone yet.

Maybe is a trend?  Seems non issue sparks so far are what I would call “later production”

Hello,
No Issues so far by my side ... bought on august 3rd in a DJI Store in Portugal... manufactured in Friday, June, 16th 2017

No problems for now.

Your Spark (XXXXXXXXXXXXX was manufactured on Saturday, July, 15th 2017

Am I reading this wrong, OP asked to get dates of manufacturing of sparks that are having problems, yet all we see are those reporting manufactured dates with no problems, so we see may June July & August with no problems. Where is this going.

Wednesday, May, 31st 2017 was the manufacture date for my spark. i have only had one issue after about 75-80 flights, the spark went in to atti mode and said it was going to pass a NFZ and tried to fly away. this was with OTG and was only the third time using OTG. i have never had any issues with the wifi.(OTG does give a better image transmission but until it is fully supported i will stick to wifi).

Well, this tells us manufacturing date has nothing to do with the cases.

Mine was manufactured on Friday, June, 2nd 2017.  I've had no issues and haven't tried any off the flight modes (dronie, tripod ... )

Could it be that those whom have had their drone fall out to the sky used the joystick command and accidently shut off their motors mid flight?  Just a thought

That actually caught my attention in the auto mode...like tracking..dronie.
I believe you guys must agree with me that those not having any issues so far are those not using those modes too often..

No, this could not be.

Mayor compass error, IMU errors and sudden GPS weak signal after 10 day from unboxing. Bought it at B&H New York, flying in Norway for 5 day with minor issues, mayor compass failure starts today after  2.5 hours of flight time. Manufacture date: Jun 22, 2017

No, this could not be.

if the joystick command to shut off engine is doable mid-flight.  DJI should disable this command if drone is move than 1m above ground.  Just my 2 cents.

Your Spark (xxxxxxxxx) was manufactured on Thursday, June, 29th 2017

My spark falled from sky when I pressed the pause button while was running sport mode full forward. Also the gimbal have problem with the screws (are not tight at all) and the fan make noise.

i have been thinking of this also!

CSC isn’t available with the virtual joysticks.

Dirk52 Posted at 2017-8-14 04:00

this actually is possible. if you pull both the sticks down on a 45 at the same time the motors shut off.

Thor1 Posted at 2017-8-14 04:45

The virtual Joysticks like he mentioned? He was talking about the virtual ones? Or did I missunderstand him?

Apart from this the spark falls in all modes.. Pano, Sport, Hover and so on. So it can't be the CSC.

I never activate this functions too. Never had problem.

i don't know about the virtual joystick but on the RC it is possible.

Thor1 Posted at 2017-8-14 04:49

Sure, with the RC it is possible. But you have to hold the CSC for 1.5sec.
For me is the JOYstick the virtual one..maybe this was the misunderstanding.

Phuong do i use the modes alot....so throw that out the window!!!!! I use trackimg and quickshots did some gestures off of a huge balcony 30 feet above a pool....no issues. I think its battery related somehow

i realize this. i didn't know we were only talking about virtual joysticks. i didn't see that anywhere in the post but i also didn't look. i have no idea what you mean in your second sentence.

Rok dont think it is a compass failure u just got a few errors move to a new spot and fly on....i got the very same errors 2 different flights had to fly in atti mode no biggie....was it alarming yes  but i got it back. Remember spark domt have any redundancies like 2 compasses or 2 gps just 1 each. So u are bound to get some interference and some errors here and there

do you think its hardware or software?

Thor1 Posted at 2017-8-14 04:55
do you think its hardware or software?

I don't know if it is Spark or battery issue,but I am pretty it is not software.again,they have Phantom,Mavic,Inspire,Matrice,...flying on thr sky long before Spark,do you think it will take them that long to fix a software issue?
Not to mention,if it is software,they should have released fix long time ago because it is easy for them to do so.

I think its the lack of redundancies when u have 2 compasses and 2 gps units u have more then double the chance of not getting an error. This is why my mavic stays in one spot like a flag pole and flying in the same spots no compass errors or imu heading errors. I just think the spark is more prone to these types of interference/ errors. So yes i think it is hardware. May e software can make it better reliable? As far as sparks falling i think thats batterys for sure

i have no idea, i don't know much about programming. hopefully we will find out soon

Your Spark (xxxxxxxxxxxxxxxx) was manufactured on Friday, June, 23rd 2017. First flight hover test it fell from half meter in soft clothes...No completely turn off. But after 30 flight aprox i have no problem.Maybe it was low battery or something...or auto landing in auto battery i dont know because i was in an another room and i hear the motors off and falling....Logs shows nothing .....Latest frimware

Correct. Mine is no issue born date June 21.

Thor1 Posted at 2017-8-14 04:55

If it is hardware then i would most likely think its bad batteries , i don't think its hardware in the Aircraft, i believe other buggy problems maybe connected to devices being used by people there is a whole variety of different devices being used some on the recommended list some not some using android and some using iOS some older units and some newer devices.

if this was an aircraft hardware problem then it would have been recalled by now, as we can see from several different polls there have been falls in every month of manufacture so lets say 100,000 sold that means there is a possibility over time of 100,000 falling out of the sky, i don't think even dji would take a chance on that.

i think you will see with more software/firmware updates this will all settle down just as it did with Phantom Mavic and inspire.
