Video tx was as far as possible from IMU, as you can see from the video, because I put it at the very bottom of the gimbal leg. Then I wonder if 5.8 GHz and 2.4 GHz can interfere each other. I have another 2.4 GHz video tx, but I didn't use it because I was afraid that it could interfere with radio tx at 2.4 GHz. So I am lost. What kind of parameter can I check on GCS to see if there is a strong interference between FC and vtx?
Do you think that powering gimbal trough ESC's BEC could have caused a problem to one of the motors?
Why Zero UAV do not say nothing at all about these problems and how to cope with it? After all we do not buy these stuff only to play like a toy (better is a nice 3D Align Heli), but mainly to use them for aerial photos and videos, so it is a must having a video link with GCS. They should address these problems seriously and tell us what can be done and what cannot be done with their FC.

The data from com3 on the YS is RS232 at a baud of 115200. The 3DR radio's are TTL therefore you need to invert both the RX and TX data between these two modules.

I did this using a SMD 74HC14 Schmitt inverter.

Set both 3DR radios and the PC GCS software to 115200 baud.

Done...

To use the Wifi module on the ground, the RX and TX data (between the 3DR ground module and the Wifi Module) has to be inverted back to RS232. I will post the diagram for this mod later today.

Great. I have found where I can get some 74HC14 and they are cheap. Look forward to your next post

Cheers
Rob

Auto take off and auto landing work with all the systems.

You will need signal into channel 7 and 8 for the gimbal outputs to work.

Here is how it should be connected.

Hi Mr_westie, here is a picture of my configuration connection between FC and receiver. As you can see I only use C7-Channel 7 for pitch stabilization, channel 8 on the receiver is used for zoom controll of video recorder.

I am now stuck by the last crash because I do not understand what could have been the reason of it and I am afraid to fly the hexa again with my video recorder or any other expensive camera.
Really not happy with this.

OK thank you very much

Check the velx parameter. This topic has been discussed several times in this sub-forum.

Archet, you do know that powering the gimbal straight from one of your ESC's bec is a risky approach considering the gimbal servos would likely to take more than what the esc's bec can handle? This is basic RC stuff that neither Zero UAV, DJI, Xaircraft nor Gaui would mention in their multirotor product manual.

My honest advise to you is to take it slow, dont rush to fly with expensive gears. With a system as expensive as the YS-X6, it's really worthwhile to use a test bed machine, a cheap quad for example, until you test all of the features and understand every aspect of the controller. Experience is the key and it will save you much money and frustration.

Actually I put the YS-X6 on a GAUI 500X quadcopter when I first tested it and it went fine, but then I wanted to test it on a larger model because i had to test its bigger motors, propellers and an heavvier payload.
Anyway, I see that it's better to go back to the GAUI 500X and test the video link, understand the interferences problems, etc..
Because I am only stabilizing the pitch servo, I thought that powering it trough the FC with three esc's becs could be enough.
Ok, I will power it from a different source. What kind of BEC do you suggest? I never used it before. Have I to power it taking off the red and black wires from the servo while keeping the white one to the channel 7 on the radio?
Then may I power it from the same source batteries that power the ESC's?
Thanks

If you connect three esc:s becs together it's even worse. Use proper BEC to power gimbal servos separately, it's only way to go.

There is no any change on the hardwere of YS-X6, only the WIFI module has something changed which can be configurated to "Point-to-Point" mode from default router mode, you can refer to the video in the first post in this thread for detailed operation.

Here are the 3DR (ground) to wifi module diagrams...

Thanks for that. I am going to get either the 3DR or the RCTimer one and give it a try.

no probs.... I'm using the RC Timer radios and they work great.

Dear archet,
Have you downloaded and read the Quick Start Guide? There is clear Warning addressed inside. The problems and cautions can be found in the User Manual or Quick Start Guide, so if you have problems or douts you can refer to it. Or emial to our technical support: support_zerouav@yeah.net

Internet and DATA Connection At The Same Time.

Whether this was posted before or not I think its very worthwhile to be send again just in case it hasnt or was missed by others.

Today I managed to connect the DATA module to my lap top directly using the new USB cable adapter. Now I have data connection between my GCS on my laptop to my copter as well as live internet feed to my GCS at the same time and have live maps working. (No Wifi module is used in this)

I also did some testing to see if I can connect the data link as well as the wifi at the same time so I can use both the PC and the phone controller together.

I used a Futaba splitter cable and connected the data module to both the lap top using the USB cable and also another cable to the Wifi module. Note the white signal wire on teh DATA Module is on the right side and the white wire on the Wifi Module is on the left side.

The GCS works fine on the PC and wiht internet and sends and received data directly from the DATA Module to the copter. At the same time the Phone app also connects to the Wifi and the app shows the data readings from the copter. I have not tried to fly it yet to see if I can control the copter with the phone while both PC and phone are connected or visa verse.

What I have noticed with his setup so far is I cannot "Get" the parameters read on the phone while the PC is connected. As soon as I unplug the USB cable then the parameters will "Get" on the phone app GCS.


Maybe there is some software changes need to make them both work at the same time?

Anyway this solves my problem of not being able to save Google maps for off line use . I will do some more testing once I can take it out for a fly and then will let you know more then.

It's a hardware thing.
1 TX can connect to 2 RX's.
But 2 TXs can not connect to 1 RX without some modification.

Will find and post.
