Yesterday I had maiden with the S800 and two 6S8000 Tunergy Zippies just taped on the Frame without landing legs, and I was really impressed. great stability, great efficiency (I did fly almost 30 min). There are vibes on the arms, but from my 14" Props on my quads I know that it is almost impossible to get rid of "all vibes" as used on a 8" or 10" prop. So to me this just flew great out of the box (gains were at 200/200/150/180).

Just right now I was out for the maiden with the Z15(+Sony Nex5n) and one 6S8000, really really great I got 13min flighttime. Video in preperation.

So I have been trying a lot of frames in the past, but this one... Well done!
(For my personal taste the frame is a little too convenient and could be a little more lightweight)
This is good stuff!

best regards

Sorry for delay.
Here are the photos I sent to DJI. Unfortunately they ignored them.
Anyway I have decided not to let it bother me anymore. I have ordered some ball links and will mod the braces as soon as they arrive.
I'm just astounded that for the money this issue would not be dealt with.
Anyway onwards. I'm looking forward to my Zenmuse arriving.

I really can not follow the "money"-point. Just take a look on the web, choose a big CF-Hex-frame (typically a landing gear is not included) take six low KV motors of that class, six Esc able to deal with 6S, 6 CF-15" props, and you are not far away from 2000$. Then you need a lot of your time to screw everything together and to solder all the leads. I might be totally uninformed about current motor, Escs, prop prices, but I think that I am not.

Hi Eoghan,

I think you are getting at the bent rods. Try to shift the the mounting point/screws a little were the booms are attach to the landing gear if that dosent help I think its simple that the rods you got are just a little to long.

Otherwise the approach of Photoship with the washer if there it to mush strain on the connection is a good work around, but i guess it dosent apply directly to your problem.

Agree and in most cases yo don't have the ability in no time to disassemble the whole bird pack it into a small box and all is good and ready for travel. CF frames in general might be to expensive. But the s800 is certainly for what you get on design and development work in the background the cheaper approach than some other common CF frames out there !

Hi EndOfDays,
Perhaps I'm not being clear enough. It's not about the price of the S800 compared to other frames. I understand that there are more expensive frames out there.
My point is that if I spend a significant amount of money on an advertised product I expect that it will perform as advertised. I just naively presumed that the landing gear would perform the task it was designed for. It doesn't and therefore needs to be modded. Fine. It's just surprising that's all. Dji make some great products and they have my support. It just seems the braces weren't very well thought out.
As I have said I love the S800 other than this.

Sorry Boris,
I didn't see your reply until just now. Yeah I have moved some stuff around and not been really happy with the results, but I'm perfectly happy to do the mod. It's really not the end of the world.
I agree with you. I think my rods are too long. I have ordered some CF rods that I will cut to size.
Thanks

@goairswiss

If you have a sudden loss of power, my guess would be the connectors.

I thought the S800 is also worth a video:

I wonder if the retractable landing gear is coming out soon and that's why they are reluctant to come up with a fix for this because it's being fixed on the new landing gear? Wish they would say something though.

Robert had said he heard from DJI that all current s800 owners will get the retractable landing gear. Ive also seen other people say this in the previous thread that was locked. If their smart they will ship the battery tray and new landing gear together.

I didn't have any crashes with the s800. I just got a little worried about the temps of the ESCs one. I took the bird in a calm area and just let is hover to 10 min barely pushing it around. I had the gains on the radio and brought them down as far as i could just to get a picture what the gains range is that can deal with and to get rid of the harsh leveling.

After the flight i touched the ESCs and i was a little worried about the temps. The bottom plate were the ESCs were on were hot to the pain level which means probably around 70 to 80 C.

Before i flew the S800 in a field with high winds and i was pushing it around to figure out it max. After that flight the ESCs didn't show any dramatic temps.

So i am confused a little and would suspect that a total failure could be do to the ESC temp.

Have you kept an eye on the temps of the ESCs ?

S800 conversion kit for 3X Pro v2 camera gimbal. Uses factory S800 landing legs. Working on mounting plate next week. No need for retracts as the landing gear rotates in pan with gimbal.

Hello

I think the S800 is a beautiful bird but I'm not completely satisfied.

1 - I have the same problem to fix the landing gear, I send an email to the company DJI with photos , the answer (there is no problem with , you incorrectly installed the landing gear ) !!!

I find this response Olé Olé after spending 2000 euro

2 - no battery support

3 - blades not balanced with different weights and impossible to balance at the hub

4 - heavy frame but not necessarily strong

5 - too much vibration in arm motor

6 - too much température Ecs

After several flights I observed that the motor vibrate much moving from a few mm !!!

If both arms side by side to vibrate together, the blades can touch them easily.

Just my analysis

DJI S800 Crash

totally fail before the three acoustic set a 12min flight time flown and have some good photos taken by an event. I always fly with a good feeling. own 5 x Dji wookoong 2x and 3x S800 Ace one and I have two Zenmuse in preoder. had the luck it has not been injured persons. Otherwise, call our company would be destroyed. I think the regulators are overheated else had never problems with a product-dji.
