Generally if your mulitrotor is moving around, either the declination is wrong or the compass calibration has been done incorrectly. I know you said you did it correctly, but tell us where you are so we can check your declination and also show us pics of your compass calibration. Once we have eliminated those we can move onto other items that may be causing problems. Show us a video of how it is moving around.


Edit: I just had a quick look at where your IMU is located. Please move it to the top of the Main Controller as where you have located it, which is below the Main Controller, has been known to cause problems. How have you fixed your IMU?

declination and compass calibration has been set many times
location is <latitude> 40.20810 </latitude> <longitude> 44.53280 </longitude>
photos and videos will be uploaded later , as copter i left at office ,

IMU i have changed and installed on the top of Main Controller via double-sided adhesive tape.

for example i want fly 10-40cm high from the ground, it is starting move ahead,back, left , right .
2 times i already crashed and it is enough for me .
How can we find out FC has quality problem ? some hardware problem or not ?
I dont know what to do , already thinking again change into DJI

That is too low.
Ground effect turbulence will make it move around.
Need to be at least 150cm+ , 1.5m

I have not been with this from the beginning but have read all the posts in the YS threads.
I have only known of 1 possible 2 faulty system.
One was easily fixed.

Thanks for that. Your magnetic declination is +5.76 which means you must enter a negative. In other words you must enter-5.76

Try that and see if it makes a difference and I agree you cannot hope to fly well at those heights of 10-40cm. Get the multirotor up to a height of at least 1.5m.

I have changed magnetic delclination into - 5.76
but in manual mode not stable, always moving and moving, i am afraid to fly higher beacuse it is very difficult to make control , i dont think the ground turbelance can affect on it so much.

Actually ground effect can cause turbulence surprisingly high, for at least 1,5 meter. Can you please post a video what kind of moving? Have you experience of multirotors before this or is this first setup? I ask because some of the movement is natural for multirotors in manual mode, if you use manual mode you have to keep it in air manually and fly it. I think you should go straight to few meters from takeoff and then see how it goes. Then take it down to tune it with P/R Sensitivity, atti gain and motion compensation.

Dear KariY
do you use QQ ,? i can switch video you can see not stable flying , file size is too big for uploading here .
It is not first setup, before we used DJI wkm on hex frame , without any problem could fly even 10-40cm from the ground .

check real servo value in the GCS. If the servo value is way off from transmitter value, you need to redo the channel calibration again. I'm pretty sure that the problem you're having can be solved by doing the channel calibration properly.

Along those same lines - I am using the SBUS system - trying to get the ext3/3 port on the ys-x6 to use for a camera trigger. Have a s-led/optical trigger cord plugged in to the ext3 port, and tried assigning a 3 way switch to operate the trigger, but when I do its shifting the roll axis on my gimbal.. ( No idea why since the roll is plugged into a completely different channel and switch) Anyone have any ideas? Everything works perfectly otherwise with the av200 gimbal for auto horizon/tilt..

alos - I am using the Futaba R6203SB RX.. can one of the 3 extra channels be used for a trigger outside of sbus/ ys-x6 controller itself with the Super T8FG tx?

Thanks all for your suggestions
Today we have replaced configuration and installed on Xaircraft Hex frame with Xaircraft motors . And it seems flight was stable , we have finished in the evening , and it was too late to try fly in air , but in indoor seems it was normal .
The reason was frame, it seems 650V4 frame with MT3506 motors and 13x6,5 props was too high shake and vibration , Motors are too powerfull for this kind of frame . we will test tomorrow and will give feedback asap.

Thanks
