hoooo!! really!?!?
Can't wait to see that!
I'm in a project to build a professionel AP rig but i can't decide now between s800, cinestar and witch gimbal....
but s800 with cinestar 3axis gimbal, it look like a good compromise

yea, S800is best flying solution now on the market.
generally i do have idea how to mount it. we'll see if it's the same

Wow, never knew

Ok, got the Z15-GH2, using an 8FG Super with S-Bus. I'm going to hook everything up in next few days on the S800. Looking at manual for Single Pilot it says it takes up 14 channels. Does anyone have a quick setup using 8FG/S-bus and the S800+Z15, what plugs into what and what channels on the Tx you are mapping everything to?

Just curious.

Z15- GH2 has hit the market..?

I think Boris got one of the first. I believe that Robert as UAV Products said he had a shipment that was already sold with more coming in within a week or two. Check over on the Z-15 thread.

Yes I have one

And???

Just came in last week.

I've experienced weird problem with one of my Escs .Even though my S800 has new V4 escs and the MC is produced after Feb 2012 , but when I tried to fly S800 for maiden test , one of ESCs burned and I saw smoke from it .
I checked the ESC and unfortunately it is unusable now .
I emailed DJI and they told me this problem is relates to Power-Surge . But I'm sure that my batteries are OK and they work flawlessly . S800 is not my first MR and I know exactly what I do . I have couple of multirotors like Octa XL , Hexa XL , DJI F450 , DJI F550 .
Any idea ?

BTW , this is what I see on the ESC: DJI. High Voltage.BLDC A.Q.04 09 v4
I guess this ESC might be the new one which DJI produced . is it true ?

Hi, I upgraded the S800 to the latest firmware (5.14a), reset everything and set everything again, re-calibrated the gps. Only change the gain for pitch & roll to 200. All the crazy stuff we had before are gone! GPS is very good. Very please, for now.

Hey Everyone.

Just building up an S800 and i'd love to see some photos of how to layout the FC components.

I've got a couple of WKM's on other craft, but would like to see some pics on how people are laying them out on the S800 frame

Cheers!

Hey everyone!
I thought I would get a little involved with this thread since my S800 / Zenmuse Z15n / WooKong-M combo just isn't flying the way it was advertised.

Lets start from the beginning, as this may also help some people.

After setting up my S800 for the first time with the WK-M, I calibrated my RX&TX (Graupner GR-16 & MX-20) and inputted the correct values (I hope correct) into the software.
Using 1x 6S 5000mah battery, and based on my center of gravity (CG) being direct center of the S800 my IMU has values of x=-7 (distance from CP to the center of the IMU) | y=0 | z=0 and my GPS has values of x:0 | y:0 | z:-17 (height of the longest GPS pole). I was using the default AP settings.
On a side note, does anyone know how exact these settings need too be? will it really ruin your flight if you are say .5 - 1cm off?

I calibrated the GPS and took it for a first test fly...flight was perfect.. flawless!
I gave it a quick few turns and back a forward motion and it was holding altitude like it was on a string.

So...super excited, I then attached the Zenmuse with my Nex7, calibrated it to a separate TX/RX (another Graupner GR-16 & MX-20) and adjusted the CG point by balancing it out with the batteries. Im running 2x 6S 5000mah LiPos on the supplied battery tray that came with the S800. Seeing as the CG point was now again in the middle, i didn't change and of the IMU or GPS position settings, nor did i change any of the AP settings.

I went out for a test fly once again, and this time the flight was much worse. the main issue was the altitude hold. It was up and down like a yo-yo sometimes raising 3-4m without my control and other times dropping as if it was loosing power. GPS seemed to be holding just fine and when i changed to full manual mode, i could 'manually' get it to hover really well. I kind of gathered that this would happen there was now a lot of extra weight. I also had to move the GPS position a few degrees to the right as mentioned in the manual, as i wasnt getting a directly straight flight when using GPS.

After some reading (this forum and others), i found that i had to change the AP gain settings.
I've since done this and although flight is much better, im still not satisfied.
The settings im using atm are: 220/220/150/180, 140/140
When using altitude hold, it seems to be holding ok with a +/- of .5m. When i switch to GPS, it starts to go up and down again.

Another strange thing that it's now doing is when i am in AH and move the s800 quickly forward by about 20m, it holds altitude as it should, but when i then bring it back toward me the same 20m, it shoots up in the air by about 3-4m & the LED flashes white twice and then back to yellow which according to the manual means 'Attitude status fair'. AHHH...so frustrating! Ive put together full MikroKopter systems in a shorter time than its taken to work this out

I have contacted DJI directly asking what the optimal settings are for the whole package combination as im not using anything but DJI systems, but no response. Im surprised they dont have a simple checkbox in the software for 'Zenmuse attached' either that or somewhere you can define the total weight of the copter and then it works the gains out accordingly.

Anyway, any suggestions on these comments would be greatly appreciated as im keen to get out and fly 'comfortably' asap!

@Koptercam,

Just make the try and go for a flight with only one pack, and see if the behavior is getting better, I think you are already close to 7kg which is close to the limit. You can of course still raise the vertical gain, to check if that has any effect in your config.

best regards

Ferdinand

Thanks Ferdinand,
Yea, I have already tried with one pack (I should have stated that).
It was still doing the same with one pack. Ive raised the vertical gain to maximum of 190, I might try 200, but this seems pretty high already.

Regarding the weight, almost all of DJI's videos I've seen it looks like they are using 2 packs. Now weather or not they are the same 5000mah that im using, im guessing they would still weigh about the same. This video in particular looks almost idenical to my setup in terms of battery size and placement...
