Hi all!

After 8 happy months and 400km of flying I have crashed my bird into a pile of stones while flying backwards in ATTI mode. I am 90% sure it was my fault (with 10% chance, that it flipped on its own when I switched from ATTI to P while still flying backwards) and current state is that the camera was completely ripped off (I searched for it for an hour, but couldn't find it ) and one wing cracked. It can still fly without a camera and with strange noise.

I don't have DJI care or whatever insurance, so I am wondering if it makes sense to buy a new one which is just ~150$ more expensive than a replacement P4P in the DJI store (without an RC and the charger) or to send it for a repair (which I think might be quite expensive as the camera costs 800-900$ without any repair costs). Thank you for any hints or advice!

Cheers, Alex

It happens to many of us. We learn from our mistakes.  I would go ahead and buy another and use old one for parts later on if needed.

I would like to learn more from your mistake please?
You say you were flying backwards in ATTI mode and in mid flight you switched from ATTI to P mode and that is when the accident occurred, correct?
If not, can you explain?
If yes, would you say that making that switch may have caused the crash or contributed and if so how?
I'm thinking it had something to do with stability, as changing modes in mid flight something caused the craft to momentarily become unstable and resulted in the tumble.  Either that or you simply crashed in to the rocks on your own by accident.
Thank you for helping

Sorry to read about your crash and camera loss. It would be nice to go back and find that lost element.

Do you know exactly what caused your crash? Post a link to that flight LOG.

Yes, DJI sell the drone without RC and charger, but it seems the  Phantom 4 Pro Aircraft (Excludes Remote Controller and Battery Charger) is out of stock now, But the customers can set an IN STOCK REMINDER. 1.png

DJI has an ongoing struggle with inventories.  I understand why, inventory is expensive, and they can't keep 1000's on the shelf just waiting.  So using LEAN principles of manufacturing they are building at the same rate as demand.  But that leaves only a small margin for repairs and replacement parts.  I think this is why we see so many complaints in the Forums about their service.  They aren't evil, but they run their inventories very tight, this can easily lead to the type of flow issues in repairs as we often see.  

But I do love their drones..... awesome stuff!

Sorry to read on your accident. Sounds like you took a massive hit. For the record, there are always refurbished aircraft you can consider through the online store as well.

Thanks a lot for the advice! I've checked and haven't found P4P, just the P4 in the corresponding section ;)

Sure! It happened exactly as you rephrased in your second sentence. I'd say it *might* have contributed to the crash:

1. I was flying *inside* the melting glacier, very carefully in ATTI mode.
2. When I was done filming that I flew out very carefully and pulled the bird full speed up and backwards to show the scale of an icy hole I flew in. It was very challenging shot and I did it right.
3. I was looking at the screen to frame the shot and when I was satisfied with what I saw I released backwards stick and upwards stick. I have also switched from ATTI to P at the same time. I don't remember what I did first exactly, but both actions were within one second. The drone should have flown about 200m and was within visibility range
4. A couple of seconds after I wanted to check where the drone is and looked away from the screen. Immediately I saw 'Aircraft disconnected'
5. Video that was saved on an RC showed that the drone flew backwards to some very big stones. This video allowed me to find every single piece of the drone, including white plastic stubs and some camera parts, but not the camera itself.

I haven't analyzed the log yet, but I blame myself here as I was celebrating a great shot too early. But I blame myself at 90%

I see and understand, sorry about your tough luck...
I guess it may not be a good idea to switch modes when in full flight.  Sounds like it would be better to stop and hover or land then switch.
Thanks for your candor!

I have only switch mode when hovering, it would be good to know if people have switch on the fly, however I'm not willing to try just to see if it's ok to do!

I have been switching while flying during some Speed tests.
I noticed no issues but having it brake up a lot while going to S mode, i have noticed more than once that my Atti mode is faster than S, but AC much more alive/sensitive in S, specially going to the sides.

Flying in Atti definitely brings new challenges. It can take time to get used to.

Well guess htat depend what you have been flying before, actually the other modes would be boring if it was not for shooting photo and film.

Bad it is that you made them so unstable and range reduced with the latest firmwares, not sure if have found the ones yet it was delivered with, so lately most flights has been for challenge and skill testing even i bought it for the camera ...

Dam bud, that's a regular "fricking" mine field.  No wonder the tiny camera disappeared into the rock pile abyss.
Origin
Late Middle English (in the sense ‘infernal pit’): via late Latin from Greek abussos ‘bottomless’, from a- ‘without’ + bussos ‘depth’.
Satin's dark abyss...

How do you even navigate that uncertain footing?

Perhaps If you wore good climbing-hiking boots and had a quality metal detector...

I searched the picture but failed to see anything shining...

That really was 't the location to be experimenting with flight modes, while on the run...



This is a great lesson for others here to learn from as well.
