Fpv trouble

At this point I really don't know what to do or know what I'm doing. I change my vtx and camera. It might be something really simple and I might be really stupid, but I don't know what to do. Any help would be awesome! I will include video. I have tried all my channel's and I still get choppy video on my goggles.

 
Hi mate cant see video , have you tried the video tx in another position on the frame it is some times helps the signal
 
I have fitted the Cheerson CS20 FPV kit and being a novice I followed the Installation procedures on Youtube, I am confident that I fitted it as shown, however the monitor is not receiving the camera images!! I have a 4K ULTRA HD camera, so, maybe you could help me? is there anything else that I need to be doing to make this work?
 
I thought I was joining a forum so that, like I said novices like me can get help, not sarcasm, by the way your comment really helped. NOT. Stop the condescending comments because it seems to me that you have the technical knowhow so why don't you just help when someone is in need of advice?

What are you using for the Video OUT on the camera?

o_O ... Nothing condescending about my comment (at least not intentionally), just basically telling you:
a.) You do not want to use a 4K UHD camera for FPV
b.) Why you shouldn't

You could've Googled the word "latency" if you didn't understand the meaning of my advice and/or how it applies to this scenario.
(Now THAT's intentionally condescending) :p

However to extend an olive branch, so to speak, I'll explain further.

FPV cameras are, by necessity, of the fastest transmission types possible. This is because at high speeds what the camera in the quad sees (which is seen by you in either your goggles or on a screen and how you pilot around obstacles) is coming at you very fast and also therefore requires very fast transmission speeds (latency) not to mention quick reflexes. Most FPV cameras are either small CCD or CMOS types and yield pretty lousy pictures because they generally have less than 700 tv lines of resolution. This is because anything more than about 600 lines of resolution causes increased latency without a proportionally appreciable increase in quality. In other words, the higher the resolution of the picture the longer it takes that picture to get to you. Also, as one increases the resolution of the transmission the time needed to transmit increases faster than the quality of the seen transmission.

The fantastic videos seen on Youtube are always taken with secondary cameras like Go-Pros, Mobius, etc or UHD cams like you mention and not
the FPV cams used for navigation. If your flying style is slow and high above the trees wanting to "film stuff" then feel free to disregard everything
I've said, as it does not apply .... however if you're into FPV racing then please certainly heed my advice.

Realizing I've completely side stepped your OP question, in admonition of your camera choice, I'll simply beg your pardon and allow Jackson to help you resolve the problem. My apologies for coming across as condescending, it was not my intention ;)
 
A bit of a long winded answer but I think you nailed it, good & proper. Some people's sense of humour don't mix with their common sense. Or can't take sarcasm. Tooshay for the answer though.

All the gear with no idea.
Oh by the way it's a cx-20
If you want advice at least give the right details, like the cowboy says, post a link.

FWIW the FliteTest folks have in fact used GoPros as their actual FPV camera for many of their videos. I'm assuming Phillip K Hearn was not planning to do any high speed proximity flying with a CX20.
 
Gyro Doctor, I wish to thank you for your understanding and for the comprehensive explanation, I apologize for being rude to you. You are right Jackson, my intention is to carry out low level flying, it's just frustrating when you buy a fpv kit for a CS20 sorry I mean a "CX20" and follow the installation instructions on google / youtube, and everything works but the transmission from camera to monitor!! I may have to purchase a FPV camera and try that, once again thanks for the explanation.

Had a similar problem...............found out that the monitor reception frequency was not as advertised..............once I got the Tx and Rx on the right frequency, problem solved.

:eek: ... Why on earth are you using a camera like that for FPV?!!

The latency of a setup like that is going to be off the charts, but you'll have a pretty view of that tree moments AFTER you've hit it :p

I thought that was just the "right" amount of condescension :cool: It did make me smile............"pretty view of that tree moments AFTER you've hit it har har!

Sense of humor is important in drones and life in general.

Have fun all!
