Some news:

Good one,

I received my new modem and Data link is now fine. I can access the parameters page and do the modifications.

Bad one,

I'm stuck with the magnetic calibration. I performed it several times and each one resulted in an horizontal red bar instead of two circles... Despite doing horizontal and vertical circles in my garden with the blue light (almost) steady...

If someone has a clue?

Thanks,

It can't be almost steady, it has to be completely steady for at least 2 complete turns

Right turn or left turn, steady light, same result...

I would ignore the PGC GCS output.
I didn't even get any lines after my calibration.
Try bluestacks or an android device.

about data link you can use XBEE PRO 900 TELEMETRY KIT from this http://www.cuav.net/store/product.php?id_product=15 via 150$. why more 199$ from Zero.Thay use this module in case

Hi all,
I have Iphone with Redsnow 0.9.10,b6
Ipad with absinthe-win-2.0.4
Both with IOS 5

On both systems, I cannot have the Yshj folder.

For those who can get this folder, can you please tell us the Jailbreak software that you used ?

Cheers

With the XbeePro datalink, do we still need the original wifi module or not?

Could someone post configuration of work port setting of the wifi module (once reached by 192.168.1.254)?

Thanks in advance.

To Zero UAV support

My YS - X6 has a huge problem with altitude hold. I over shoots rapidly after 20 to 30 meter I and it does not respond to throttle in Altitude or position hold mode I have video to show what iam telling.

YS-X6 stone fall recovery (2 min 36 sec)

I have to switch to manual and bring it down from 140 meters. Luckily I my copter did not have even a starch. When i played back the HJ file i notice that altitude reading where worng so its a problem with brao on IMU

please help me regards

I have had a look at your file and I noticed your Shake level was sometimes greater than 40 and 90 percent of the time it is in Red which means that you are using a frame that is very unstable and the vibration is having an impact on the IMU. This is the problem when you use cheap frames. Even carbon fibre frames, if made badly, or use too thin material, exhibit the same response. It could also be loose nuts, bad bearings, bad motors and unbalanced props. Who knows, but there is something seriously wrong with your frame.

If you have a look at your vibrate state. It is supposed to be between 1-10. yours is showing an average of about 18 and peaking at 20 and showing FB which means it is Front and Back

I also noticed that your xekF Veld was sometimes greater than 100+which would cause a solid white light to shine. Now the manual says on page 46 of the latest Quick Start Guide - "The velocity after Kalman Filtering. Normal is when it displays a value between 0-20. When the velocity exceeds normal range, the LED will be solid white and suggest you land urgently." Which it seems you ignored.

I suggest that you re-look at your frame and maybe get a new one. Something less prone to vibrate. Maybe its your motors or your props. But check everything. The other suggestion is that if you are going to be doing some serious flying, do it in Manual mode.

I would like to see you frame, out of interest. The only time your lights on your GCS were showing green was when it was on the ground

Done, at least...

The problem: Compass chip is under the GPS plate. My GPS Unit was sticked directly on the carbon frame of my bird, with the mag chip over a steel bold.

So it was like a Faraday cage and compass reference was bad.

I moved the GPS/Compass unit on the supplied mast and compass alignment is fine.

It may help someone,

Marc

well done Marc.

That is why the first thing I ask for is a picture of the system setup.
Simple mistakes can usually be resolved in 2 posts vs 10.


hemanthtguru , the video is not working for me.
That is some nasty shake, crash material for sure.

From manual
"Value below 20 is normal when the craft is static on ground."
Inflight it would depend on how fast you were flying?

Thats an indication of RF interference affecting the IMU...

Of course you can buy 2 Xbee Pro data link, and use it without any problem .
one months ago zero make some action and offer 99 usd data link, actually it is xbee's real price , and they offer it first hand price, so you could buy directly Xbee Pro data link and use it .

I have experienced for weeks a bad manufacture configuration of my wifi module and couldn't use.

Thanks to the help of guys of this forum, I could solve the problem.

As some people are also concerned with this wifi problem, I put in one pdf the whole procedure to initialize and configure the wifi module.

Thanks again guys, good forum!

I have a load of Xbee Pro 900s. So can I just plug it in and it works with the GCS? any settings that need to be configured?

Set them to 115kbps, 8,n,1
FC>xBee - xBee>SerialUSB>PC

Would be my guess.

What is a decent vibration reading? I see up to 10 is okay, but what is a good reading?

What frames and motors are you guys using?

I can see why some people have problems. They spend a fortune on a good auto pilot and stick it on a piece of cheap %$#@ and use rubbish motors and unbalanced props.

I'm using a Carbon Core 950mm hex and Avroto 2814 motors

Good number of sats.
Low shake.

0:41 off axis gps drop
1:15 lift off
4:01 radio loss?
4:15 Back landing (RTH) engaged
4:22 "xekf Velx" peaks at -458
4:32 radio control restablished? .DTB 26m
4:34 "xekf Veld" starts to rise, peaking at -141
4:37 full throttle for 1.5s does not result in alt change
4:44 Low throttle for 1s does not result in alt change
4:46 Switch to manual at low throttle = crash
4:50 impact, throttle off

-Analysis
Depends what you trust more, the AR8000 or YS-X6.
I am going with the AR as failsafe is throttle low and range was less than 70m.
During normal flight minor corrections are seen in "Manual servo position"
At 4:01 MSP input is stalled.
When input is working again throttle does not result in Alt change.
I can not see any reason why the YS would ignore MSP.
The sat signal does appear to go bad at points but not at the same time as stalled input.

Not responding to throttle is a problem.

The bad data the YS was getting may have caused it to ignore MSP


-Warning signs
High "xekf Velx" blip while on ground
High "xekf Velx" blip while on in air


-Done differently
Do not launch from a confined space, balcony?
Once RTH was enabled, do not touch mode switch.

Agree. While it is flying in Back Landing Mode, do not push throttle to max and then down to 20 as it does nothing. The switch to Manual mode when the throttle was low (20) probably did it. At 4.50 the real time throttle was down to 4 and that is not where the crash took place.

I and a few others I know, have switched over to manual mode while Back Landing, without a problem, but the throttle was still at about 50%.

The problem is in Auto Hover mode, to make it move up or down, it needs such extreme movements.

I know they say in the Manual that if the throttle is low and you switch to manual, the motors will cut off. Now I am not sure how low is low. Maybe it looks like 20 percent is low.

I would like to ask 2 questions, just so we get a clearer picture..

1. Can you tell us what the battery voltage was when this switch over to manual took place (4.46).
2. Can you tell us what the ESC's settings were. Lipo/Nixx and Soft Cut off/no cut off or hard cut off.

Rob

1. 11.64v
Idle start of flight , 12.57v
10s after power up hover, 12.00v

2. Owner will have to answer that.

Personally I wont even launch the copter if I found that the xekf velx number was that high. When I crashed mine upon lift off about a month ago I thought it was the system's fault. But I realized that I'd changed my setup the night before so I had inadvertently introduced interferences to the IMU. So I did a couple of ground test and the result was conclusive, source of interferences were affecting the IMU. The fix was really easy, I just repositioned those sources as further away as possible from the IMU and it's all good now.

It is important to note that magetpr's setup included 800mw 1.2ghz vtx. From my point of view, the vtx and possibly other sources might have caused harmful interference to the IMU. Just try that by powering up the copter and move the source of interference close to the imu and read the values of xecf velx in the GCS.

Since the values were not accurate the system didnt perform what it was supposed to do so that may explain the crash.

So perhaps a new protocol could be introduced in which the system would deny throttling up upon take off if the xecf velx value reaches a certain high number just before take off.

I have a question for someone.... if I am always seeing a white light when trying to take off, afterreading everything here it seems my vibrations are to high, so the actual question.... Can I extend the LED wires? If I use 4 conductor sheilded wire, another 6 inches or so should be ok? This will take it totally away from everything for the RF noise as I read a few pages ago??
Thanks in advance....

Oh, I am getting rid of the F550 plastic arms unit for aluminum arms, or a new frame altogether

If it were me I would address the vibrations before flying as the possiblity of a crash could be very costly

Well, to be honest, I went through all the setup steps, and I got to the test flight in manual mode, flew perfect, then I saw my vib was around 10 or so, then started to see a white light, landed. Read. Flew again, and when I tried gps mode, it started to shoot straight up, and fast, rechecked vibs, way up in the 20's, and a white light again.... So I landed and started reading some more, And then good old winter showed up and it snowed, so I'm ordering parts, then will try again in the spring, or sooner if we get a nice long chinook

I have been battling over the last while (could be a month or two) to load saved waypoints on my Android HTC Flyer Tablet and also on my Samsung S3. Could save but not reload them. Everytime I tried to load it would shut down the app.

It turns out that in South Africa we use the comma as a delimiter instead of a decimal point. So every time it saved the file it saved with a comma as the decimal point and when it came to load, it did not know what it was reading. We finally resolved it today with ZeroUAV and they have revised their App, which is busy being tested. But, for those of you in Europe, South America and South Africa and a few other countries, you must also have been having this problem.

These are the Countries affected (Green) and Blue uses the point (full stop)



I would think that the revised App will be sent out in a few days.

I like the the way the new App has been laid out. It is so much easier to use.

Well done ZeroUAV.

hello,
i have a problem of not enough channels. i'm using a 9x with frsky modules with a max of 8 channels.
What i really want to do is have my quad set up to run with 2 controllers. A pilot flying fpv style and a photographer controlling the camera.
So my question is this, can i run 2 2.4ghz systems of one quad, or will the signals interfere with each other, and or shorten my range.
I want to order another 9x and frsky combo for the photographer.
I was thinking of perhaps using a second system on 72mhz, or 30mhz, but it would be easier to just duplicate the stuff i'm already familiar with.
Any help much appreciated !

hI GUYS

Any one noticed at what time Zero UAV support will be online on SKYPE, I have many clarifications Please let me know

I know a guy in south africa he is using 2 controllers one for video and one for controlling the drone

But this is YS thread right? Sold my wkm in lack of trust for latest firmwares. I think YS:s are just playing nice, that's why quiet here.

Hi Maximus, I have installed other app so I can see and upload any filesin my ipad trough the Mac, so I have unzipped the .rar and upload the YSwifi.app to /var/mobile/application in Ipad.

but nothing happens, i dont see any app

Ok its already solved. I was copying the files to the wrong directory, now works.

Thanks any way
