S-800 arm replacement

Hi all I had a little accident today.
My 800 slid across the lawn and tipped over breaking one arm.
Any idea if parts are available for sale?
I checked the DJI site but I see nothing there.
Also my dealers site don't show any parts for the 800.

Thanks

After I replace the arm I'll be putting her up for sale. (Frame only)
She only had 2 flights.
Stay tuned for the sale annoucement.

Cheers

Yes I got one late last night, saying they would be in touch soon. Someone called Benjamin is organising the returns. I have been issued with an rma number. I hope this is sorted quickly...

I am quoting the first post so more people will read it.

Now it looks like there are 3 options.
About option 1, I would not be comfertable soldering away the 6 resistors and replacing them with a jumper.
Not because of the job itself, as it's pretty easy to do, but IF I was to have a failure later, I don't want to risk being blamed for the crash by someone raising doubts about the soldering job.

Also, I don't want a quick and cheap (for DJI) backyard fix. I guess there was a reason for the 6 resistor being put in the ESC's in the first place.
Can someone more knowledgeable about electronics than me explain what these resistors do in the ESC, and what changes once they are removed?
I do know resistors generate heat and reduces the voltage. Is this just an easy fix to reduce the heat and therefore the failures of overheating ESC's?

I want a ESC that is designed for the job that does not require dodgy fixes.
Thats my standpoint.

Also. What about the soft arms and the vibrations they cause?

Option 1: End users can fix ESC solder jump wires to the six resistors per instruction sheet.(Instruction as attached.)

Option 2: Take out the ESC and send to dealer for ESC replacement.(we will assign dealer to help)

Option 3: Sending the whole arms to dealers designated by DJI, dealer will fix ESC and return.

I am comfortable removing 6 resistors in terms of performing the actual task, but as you stated I'd like to know what it is I'm actually doing and what they were supposed to do in the first place.

BUT more worrying is the wobbly bendy flexy soft arms. What is the fix for them ?

What kind of warranty are we getting if we attack our unit with a soldering iron?

I think I'm going to buy a frame from an established frame manufacturer. My confidence in the s800 is just about zero. It's a real shame 'cause it sure does look cool.......

Yes. We need to know that. Hopefully someone knowledgable will explain the purpose soon.

Same for me.
What DJI SHOULD DO imo. is to issue a recall and send their customers a shipping note using their DHL/ UPS account etc. and replace the ESC's/ arms quicly and free of cost for the customers whu has invested a lot of money in their faulty designed product.
