Don't worry, I shall never blame you for crashing one of my drones. It is telling enough that you keep on blaming and spending 24x7 in threads about drones that you do not own. Couldn't be more revealing...

More false accusations?  Or are you ranting perusal at command of your master?

Where have I blamed Mavic 2 on problems with my Mavic Pro Platinum or CrystalSky Ultras?

What a crock of sh#t, had to stop watching when the guy said he crashed his drone into a bridge flying backwards LMAO,  Do us all a favour, put it where the sun don’t shine.
Your pushing the self destruct button again , I beleive it was supposed to be posted in the Mavic Pro section, but won’t cause as much hysteria there. Lol...

Nope.  Posted right here.  In response to one of your posts right here.

If you had bothered to watch video, you would have heard explanation was to why some of have no problems while others have lots of problems.  It deals with production curve.  Initial production, consumer demand, production ramp-up, and slow return to care and quality of first batches of drones.

But alas it is easier for you to dismiss and scream "What a crock of sh#t".  Even though I didn't make the video!

Your here to cause as much hysteria as you possibly can, you did it on the Mavic Air section of this forum for many months now and you will continue to do it here on this section of the forum, you don’t own a Mavic Air you don’t own a Mavic 2, you have said here you never will, but you seem to invest almost all of your time on both these sections of this forum and for someone with no vested interest except to cause confusion and hysteria, it’s very easy to figure your not doing it to help anyone.

Looking at your log, redundancy kicked in a couple of times, and you would expect this to happen if something is askew, but apart from that , to me this looks like an aircraft malfunction.
Sync your flight, Contact support and arrange to return , IMO I believe you should receive a new Drone.
Good luck.

Yea same here....but what’s weird is nothing reported between the 200+ feet and 0...The gimbal roll error seems like that’s where it went out of control and the gimbal was just trying to keep level.....maybe a big bird with a fly swatter?

You call it Hysteria, and I see it as informative discussion.  

Guessing my  post  on length of Time Mavic Air has been released vs. last Mavic Air firmware release, got you all riled up.   Facts are a hard thing, aren't they?!

Funny thing.   I didn't open threads about Mavic 2's dropping from sky.  Yet you want to blame me.  
Must be that Living in Head 24x7 rent free thing.

You must have dug that information out of .DAT log file.  Did not see it in output from FlightLog .txt file?

Never mind, I missed where you stated it.  Had to seperate things out.

The following video provides an explanation as to why there are some that say they have had no (or next to no) problems, and why others have had problems with DJI drones.

https://youtu.be/b6ysJe6sDok

I got a chuckle out of the guy who kept taking off over & over, in an area he repeatedly stated was a NFZ, only to watch the drone immediately land itself again & again.

Fortunately he decided to take it in, to be looked at, for "the problem".

I don't suppose taking off from somewhere else, like where it wasn't an NFZ, ever occurred to him?

His remarks are confusing.  One time he says he is near a NFZ another time he says he is in a NFZ.   I don't know rules where he is at, but he seems to believe even in NFZ he should be able to go up to 50-meters.

Anyway, he does say in video he did think of taking drone else where, and did**.  He says he went ?????? (far away from everything) with a friend who has two Mavic Pros.  His friend's Mavic Pros would fly without problems, while his Mavic Pro still would only go up, then back down instead of hovering.

Little different experience.
Four previous services to DJI in 7-months.
Two upcoming services to DJI.

My personal experience.  I've owned 11 DJI drones. (Actually 12 but I sold a P4P before activation)

P2 Vision+
(2) P3 Standards
P3 Advanced
P3 Pro
(2) P4 (sold the 1st to buy a Mavic Pro)
(3) Mavic Pro (2 regular, 1 Alpine)
Mavic 2 Pro

My Vision+ three times landed unexpectedly due to a flakey battery (same battery all 3 times I just didn't realize it until later), & was once brought down by a bird.  I lost my original Mavic Pro when I clipped a boat antenna skimming over the marina.  My fault...didn't see the thin aerial on the phone display in the bright sun until the last moment.  My second P4 once landed itself during a Litchi mission.  I recovered the bird & have no idea why it landed?  One minute it was 250' up, next minute it was landed, half a prop was missing with no other damage.  Best guess from log data is the prop threw a blade mid air & she slow spiraled down.

I have over 1000 flights, 4+ million feet of logged flight in the Go app, & at least twice that unlogged in Litchi (I mostly fly Litchi Waypoint missions).  That's a lot of DJI aircraft & a lot of flying, but I have yet to experience a bad bird.  Without a doubt there are defective units, but I have not had one.  The build quality & performance of my units has been excellent so I've never required factory service or repair (not even for the bird incident).  It has been my experience that DJI aircraft are extremely well engineered & reliable machines.

Eh.. I was flying the mavic way back in 2016. It did have problems early on with emf, had to open it up and address the emf issue by shielding the wiring to the rear motors. Since then she's almost immune to emf with 2 compasses. Early adopters will have things like this pop up.

What bothers me is a lot of supposed pro's posting bad footage on youtube right now. I mean like half a million subs starts the blades up folded xd Autofocus mess. How do these guys get a following?

I love litchie.. All I fly really

Want to trade for your working MP2?
I should warn you - DJI has already said Mavic Pro Platinum should not be flown.  

Maybe it is a case of Tolerance.  Some don't mind putting up with minor problems, while others have issues with scratches.
I feel after paying $999 for CrystalSky Ultra brite, that two Function keys (Custom buttons) should function when it came back from DJI service.

Maybe there is some setting buried in sub-menu that I need to first enable to allow F1 & F2 keys (buttons) to be set?  

I have asked, but nobody, including DJI support, has said there is.  CrystalSky manual of zero help.  Nothing on Custom, Function, or F1, F2 buttons other than where located.

If you know, by all means please advise.  I would rather CrystalSky not go back in, being 1) Would be needless, 2) Longer turn around, 3) something else cease.

Eh.. I was flying the mavic way back in 2016. It did have problems early on with emf, had to open it up and address the emf issue by shielding the wiring to the rear motors. Since then she's almost immune to emf with 2 compasses. Early adopters will have things like this pop up.

What bothers me is a lot of supposed pro's posting bad footage on youtube right now. I mean like half a million subs starts the blades up folded xd Autofocus mess. How do these guys get a following?

I ordered the Mavic Pro on launch day & was part of the group in limbo for a couple months.  Finally arrived in December.  Mine was awesome & never had a single issue...rock solid...but I did have a friend who picked up one of the first units to arrive at the local Apple store.  He sent it out on a long Litchi excursion over Baltimore & when we watched the video we like to died.  At one point in the flight, right over the Inner Harbor, it just sort of lost its mind.  It sort of just stopped & drifted around, dropping down to around 2-3' above the water, almost hit Constellation Pier, this went on for a couple of minutes just wandering aimlessly.  Suddenly, for no apparent reason, she perked up & continued on with the route as if nothing had happened.  The drone version of going on walkabout.  He returned it for refund the same day after watching the footage. My guess is it lost GPS lock & wandered around until the signal came back.  Unfortunately he was so dismayed that he didn't save the log before returning the drone.  He wound up buying a P4P when it was released a short time after.

Want to trade for your working MP2?
I should warn you - DJI has already said Mavic Pro Platinum should not be flown.  

No thanks I love my Mavic Pros.  They are unlocked to accommodate my rogue flying style!  

Where is DJI warning owners not to fly the Mavic Pro Platinum?  I don't own a Platinum, but I wouldn't mind having one to complete a Mavic Pro set as I have the original & Alpine.  The Mavic Pro will be a capable bird for years to come, IMHO.

I don't know how many Crystal Sky units have sold, but I do recall seeing quite a few issues with early units.  In a forum like this complaints always outweigh kudos, so one can't base an overall opinion on the reliability of a product from a support forum full of users with issues & complaints.  I never wanted a Crystal Sky, but I have seen the photos of the Mavic 2 RC with the built-in display & find it quite intriguing.  Definitely something I would be interested in & I suppose it is basically a small Crystal Sky unit morphed with the RC.  Very cool looking in fact.  I hope you are able to get your CS working properly.  I assume you bought the big one for that price?

Yep, I guess you saw on airdata or what was it back then healthydrones? You'd see it was flying in circles. It was emf to the rear motors causing the compasses to go nuts. Instead of a recall which would have cost them a arm and a leg, they had the drone drop into atti instead. The real fix was triple shielding the wiring to the rear motors. Using older software you could see the compass went from 200-300 in flight to under 50. Guys at mavicpilots were twisting the wiring to try and cancel I remember but that wasn't good enough.

All dji and a lot on this forum said was get gud when it came to mag interference in a area. They never could see the forest through the trees I guess, went with it's just more sensitive than the rest.. with 2 compasses xd. Guess it was better than a recall. A fixed mavic never needs calibrations, you just fly the thing.

Interesting piece of information.  Isn't that what DJI still does when there is a Compass problem, go into ATTI mode?
Toss out GPS info and forgo using XYZ intertia and gyro sensor data (Surge/Roll, Sway/Pitch, Heave/Yaw).

Well not before think was nov 2016. The 1.2.9 firmware and down wouldn't drop into atti which is why you would see the circling especially after flying fast (more power, more emf).

I was talking about you trading your Mavic Pro 2 for my Mavic Pro Platinum.

Thus fair warning about, DJI support having told me not to fly Mavic Pro Platinum, because of two problems it came back from repair with.


Now, I wouldn't want to be accused of back-pedaling; if you want to trade your working MP2 for my MPp...

Why would I trade a perfectly functioning MP for a MPP that has been serviced & warned not to fly?

Well it appears you chose the wrong option, dji approved dealer is not the dji company dji will always advise to return direct to them, you have no case number and this is why you have no support but it sounds like this very much suits you, it looks very much like your gripe is with your dji approved dealer which dji would not recommend sending back to, if you adopted the same channels as most people have done then you would almost certainly have your drone back.
Maybe your not half as smart as you come across , but you have given yourself plenty of scope to whinge which it seems you like to do, your starting to sound like a long playing record.

Oh, but i loveeee long playing records. They stood the test of time, they still sound amazing, back in fashion again. They are like very good working antiques. Also, till today, i have some good support for my old, old Nad record player. What a life we live.
I take it, just because YOU say so, it doesn,t happen, the bad support....
On the other hand, you don,t sound like a long playing record, you sound like a brown nosing DJI fanboy that lost touch with reality at some point.
That is unfortunately the way I was told to do it, and I will continue to say, DJI approved service centre is DJI. I was not aware that I could send it directly to DJI, at the time, and i honestly thought that the local DJI service department, would sort out the problem faster.

DJI Cape Town, Dji China all have the same name DJI.

However, it looks to me as if something is causing the FC to fail - whether that is overheating or a firmware bug of some kind is hard to say.      Both IMUs report the same temperature (65°C), which is appears to be a set point - the IMUs on mine run at exactly the same temperature. The CPU temperature is not recorded as far as I know. Do you know if the fan works(ed)?      This looks like a clear case to request a replacement.        #37

Looking through verbose CSV file, I have not spotted anything that points to MP2 about to do a high dive crash.

Without source code to look at what messages in .DAT log are attempting to communicate, not going to get very far.

Definitely need to have DJI look at FlightLog file and BlackBox data.

Best of Luck!

Don't bother, there are 2-3 people in this forum defending Dji to death... perhaps they are trying to get some "special" treatment from them. I hope some day the will be in your shoes.

Thanks man. I always maintained that it is impossible to make something so advanced, and NOT have problems. That would be fine, but to not support properly, no matter from which country you come from, is in excusable.
And honestly, i do think that some of them were in our shoes, and frustrated at some time or the other. They might just have a bigger tolerance for BS than us. Not that anyone would admit that.

True.  But, having worked with and suffered through cutting edge Tech, this Tech is not that advanced.  The problems lie elsewhere.

You alluded to one of problems, ''not support properly'' (aka inadequate support).  You can't provide proper support for this level of Tech, by having support personel rattle off canned responses or possible solutions from look-up guides.  That kind of support barely works with internet services.  

There also appears to be a disconnect between support we make contact with and next support layer.  Two recent cases where I had to re-provide information to first layer is not a good sign.  Nor was one of responses I got back a good sign.  Like person got two cases swapped or confused between drone models.

Nor can you provide proper support when company fails to acknowledge or openly deal with problems.  An example was - Failing to offer a way for those having problems with .0400 to rollback to .0300 FW.

Couple of people here have mentioned another problem aspect - DJI protecting their code using obfuscation, interference code to prevent reverse engineering (via debuggers and decompilers), and on-fly decryption of some key parts of code.  If true, as a customer who paid for company's products, code being key part of it, to work properly and reasonably efficently, I reject such an excuse.  When DJI's own custom SmartDevice suffers from lag do to enabling supported options, there is without doubt cpu cycle burning code bloat occurring.

You are wélcome.

i do have tolerance for issues, especially when adopting new technologies. However I am not tolerant with:

A resounding I AGREE  from me. I sometime get the idea that people think this droning hobby (yes, hobby) is rocket science.

Also, this Captain thing should not be taken toooooo seriously. There is a few level 1 guys, with more experience flying drones, than Captains around here. Captain here only means you post a lot of stuff, not that you could necessarily fly a Boeing 747. (to those who actually can, sorry man, you are not included.)

And yes again. I often wish we could get someone clever, to just hack the whole DJI App code, in order to get functions on some of the drones that should have it, or just to get the things flying without problems. Much like a performance chip for your car. Install the thing, and reap the awards.

I higly doubt they have sold half a million units already, but even then, its not the amount of crashes but the short period of time in which they're happening. Similar thing happened to the GoPro Karma when it launched 2 years ago and they had to recall it. Im not saying this is the same but we'll have to see.

salve...il mio e caduto 3 volte .....la prima a circa 1,50 CM    con danni al gimbal  ,la seconda a circa 30 metri  per fortuna è caduto su un albero  con danni solo eliche  ( recuperato con piattaforma  aerea ) la 3 volta da circa 15 metri sempre su un albero con danni eliche ( recuperato con scala ) io credo che ha questo drone c'è da modificare il gancio delle eliche  con qualcosa di più solido e qualche cm più alte rispetto alla scocca
