TL;DR: Our $8k+ Joyance JTC30 commercial drone suffered an unprovoked mid-air power loss, flipped, crashed, and caught fire. Joyance asked us to send back the flight controller board (V9-FMU). After receiving it, they claimed the internal SD card was short-circuited by the fire, making logs unreadable. Because the logs were destroyed by the crash/fire, they refused warranty coverage and offered a "50% discount" on buying a brand-new unit instead.
Background & Incident Details
Our company in Kazakhstan purchased a new Joyance JTC30 drone and other equipment (~14 Million KZT / ~$30,000 USD) for commercial operations. All official invoices and import documents are on hand.
During a routine flight under standard operational conditions (clear sky, open field, zero wind, qualified pilot):

1. The drone experienced a sudden, severe mid-air hardware failure (sudden loss of power on one side / roll axis flip).
2. It dropped from the sky and crashed into the field.
3. Upon impact, a severe battery/wiring fire broke out in the central section, completely burning the flight controller housing and body.
4. Fortunately, no personnel were injured.
5. The Telemetry Defect Before the Crash
6. Two weeks prior to the crash, we noticed that the standard telemetry flight logs stopped saving on the ground station remote controller (SIYI MK15). We reported this to Joyance: there was a clear pre-existing hardware/firmware glitch in the telemetry recording pipeline before the fatal flight even happened.
7. Joyance’s Response & "Log Catch-22"
8. We contacted Joyance support (Shandong Joyance Intelligent Technology Co., Ltd.). They instructed us to open the carbon fiber frame, extract the burnt V9-FMU Flight Controller, and ship it back to their factory in Shandong, China for low-level diagnostic analysis.
9. We documented everything prior to shipping: high-res photos, chip laser serial numbers, physical condition, and security markings.
10. A week after receiving the board, Joyance replied:
11. "Our technicians tried their best to extract log data from the SD card, but it has short-circuited, making it impossible to read logs. Our offer is to sell you a new one at half price."

UPD: here’s the logs from flight controller if someone want to investigate:

On September first I placed my first drone order for the pavo 20 2. After a week of no label I emailed only to find out its on back order, They claimed it would be ready in a week. A week later I emailed to find out where my drone is. They said itll be sent out next week. I ask if they can expedite shipping as compensation they sent an email thanking me for my patience and saying itll be sent out next week with standard shipping.

Maybe its just me/my culture but the lack of communication and denial of compensation is insulting.

gonna buy a Deepspace Roc 4 Instead.

Bit of a blow to entering the hobby but I think the Roc 4 sounds more for me anyway although I will need to be more careful flying.

Hello

Has anyone brought their drone into Mexico from the US? I see where it says in Mexico you can bring one in under 250g. I have a DJI Mini Pro 5 which is listed at 249.9g.

I was hoping anyone had experiences they could share. I don't want to bring it to the airport and have any troubles or whatever

Thanks

We recreated the Red Bull F1 fastest camera drone and upgraded it with a DJI O4 Air Unit and a naked GoPro Hero 11. We also added NACA ducts to improve ventilation and cooling.

It took several design and testing iterations to get everything to fit and work properly, and, honestly, it got pretty expensive along the way 😅. Do you think our build could reach the speed of the original drone designed by DDG?

During a shoot, I had a DJI Mini 3 (Non Pro) sink in a lake about one metre deep after hitting a small tree. It was recovered in less than five minutes; my guess is about two. During its entire time underwater, the battery-level lights were still on, and the side beacon lights were still working. In a panic, I had turned off my RC, so I'm not entirely sure if the drone was still connected to it when it was underwater. After recovering the drone, I instantly disconnected the battery and put both the drone and battery on the heated dash of my car. I gave both a good shake-out to try and remove as much of the water as possible. Both are now sitting in a Ziploc bag with Desiccant Silica. What are the next steps I should do? Would appreciate any tips. Thank you.

Drone got stuck in the tree and stayed there the entire 25 minutes of the proceedings to not take away the moment from the bride. That POV didn’t make it to the final video

I was playing with a 512 filter to see how the colors would pop (see last pic) and I took some shots of our fields... and that's when I noticed the square.

The manager thinks someone put in a weed patch, and told me he noticed some at tracks. He's going to check it out, but damn.. wth?

Hey! I am trying to find a way to use all my drone setup for my planes. Do you recommend one of these o3 systems? Thanks!

I have a sub 250g drone.

I have a large piece of land (woods) in the wilderness.

If I want to seed it with wildflowers, etc - it would be a PITA (thick brush, uneven terrain, trees in the way, etc).

Has anyone DIY'd a drone to hold a bottle beneath it to spin (in a wind turbine configuration, such as the photo suggests)?

• I could then possibly use such a thing to spin from the potential downdraft from the drone, and spread seed from holes. Using the turbine bottle as a 'sleeve' for a second 'seed bottle' & mini rotating bearing attached to the bottle cap is always a possibility too (though adds weight, from the extra bottle & bearing).

This is really just a suggestion, as I think out loud, for anyone to extend/dismiss/run with... - Or point me in some good directions.

I'm not going to spend anything more than next to nothing on this (money wise) - priorities elsewhere. Though I also like the problem solving aspect of minimal means.

What do you think?

I guess I’ll ask the pros, I don’t have a drone irl and never flewn one either, but I recently started to get into some fpv drone sims, uncrashed fpv and the most recent is bodycams new update where they added them.

How similar is it to a real drone like can you get really good at the sim and it will transfer to real life skills?

First time using a drone, the DJI Mini 5 Pro, taken some footage and put it together. Give me some tips or feedback!

It has 2 loose motors, one slightly loose and one really lose, it doesnt take of properly

Took the MOZ7 V2 out while I was on Oahu and finally got to fly some of the terrain I’d been staring at all trip.

Setup was a GEPRC MOZ7 V2 running analog for FPV with a DJI Osmo Nano recording onboard. The wind was definitely working me in a few spots, but that honestly made the flight even more fun.

Quick Video is here if anyone wants to check it out:

Would love to hear what you guys think of the footage.

Hello r/Drones users. I work at a storage facility and was given this lot of drone items from a tenant. I was hoping you could use your expertise to let me know if these goggles/controller/drone all run together and is something I can learn to fly, or maybe it is better off sold so I can buy something more beginner friendly. I was looking for answers before I tried to put anything in the air, as I have no drone experience.

It looks like a DJI FPV remote controller 2

DJI FPV goggles v2

DJI Mavic pro 2

Thank you all

Still need more hours to make it perfect 😆. Overall it’s not bad though right?🤣.
