Great stuff, Brian!

I love the KISS approach. I was testing one of IBCrazy's antennas that I had made for my video transmitter about a month ago. I rigged up my FPV pod and put it on my deck to transmit, and I needed to do a quick-and-dirty range test. So I grabbed a VRX, stuck a rubber ducky antenna on it, hooked it up to a little monitor I had handy, and carried it down the street in my hands.

About half way down the street, the LIGHT WENT ON!!!! And presto, I realized that I was carrying all I really needed for a simple ground station. Since then, I've made a new antenna for it (Thanks, Alex!) and put the little kit into a bag that I take to the field.

So YES, KEEP IT SIMPLE!

Thanks for distilling so much about FPV into this handy little list. It's great!

I second all of these lessons! I've been through basically all of the myths and learning process they speak to. I wish that this was the first set of pointers I'd encountered as I started FPV 3 years ago. And I should have come back and re-read it periodically. Whether this is a sticky or incorporated at the top of a "getting started" thread we owe it to newbies to get this information in front of them.

Humility is everything. Being humble means knowing your limitations and admitting your lack of knowledge. Then, people WILL help and are glad to.

Great sticky

nice! i have a question does your range get effected any by being carried around? and being near your tx? i am thinking of putting mine on my tx tray

also is that a prism tv? i just picked one up at cvs for dirt cheap used it a couple day ago for the first time, seemed to work good, may need a hood though

Well, so far I've only tested this system once due to my schedule and the cold/windy/rainy weather we've had lately. But to answer your questions,

Range - According to Google Earth, and my video, I've had this out to a good 2000 feet with great video performance. As far as it being carried around, I think it's an advantage so far, because if I feel I need to move the antenna, all I have to do is adjust the direction I'm facing.

My RC system is 2.4, and my video system is 900mhz, so I am not aware of any issues with the rx being close to my tx. Again, I've only flown it one time so far, but I've not heard of anyone having a problem with that.

Yes, that's a Prism tv. My video goes from (1) my VRX to (2) my Aiptek MPVR to (3) the tv, which gives me good static and only goes to "blue screen" if the whole thing loses signal. When testing this system, I noticed that the Prism went to blue screen when the Aiptek went to static. So I figured I'd feed the tv from the Aiptek for better low-signal performance. It's working GREAT so far!

If you look closely, you can see that I threw a little black foam in my ground station pack to give me a little bit of a hood. I have not flown this in direct sunlight, so I don't know how it will perform yet. The theory is that with the Skew Planar Wheel antenna being as great as its reputation, I should be able to move my position around so the sun doesn't bother me too much while still keeping a great signal. The SPW antenna's reputation is THAT GOOD, so I'm banking on it delivering on it! I'm also toying with the idea of putting the antenna and the VRX up on a mast for even better reception and range, but we'll see if that's necessary first.

Hope this answers your questions!

Can you tell us about your system?

Bob

yes i can.

Basically a stock 900/500 system from range video, with their dipole antennae on both sides. A Futaba 9c on 72mhz with a 3rd joystick for pan and tilt. Basically im still at the KISS stage that this thread talks about. I usually fly at about a half mile max but most of my stuff is just buzzing around overhead.

On the rx side i have a dual output rx that goes to the screen or goggles depending but im liking the screen betteras i feel less reliant on the video if something goes wrong. on the other output it goes to a roxio easy vhs to dvd capture card and into my laptop. i did some testing in my apartment with the video signal and the tv seemed like when it went to bluescreen it recovered quick enough, but then again i dont push my range to really worry about it. i can usually turn the plane to get better reception.

at the end of the day, they are all SD transmissions, haha.

that said i do really enjoy the extra image quality of 5.8. It's really subtle, but noticable.

doesn't stop me from flying 900 on my apprentice tho, lol

There are advantages and disadvantages to this:
Pro:
People can contact you if someone ever finds it

Con:
If your plane etc happened to loose signal and crash into something causing damage to propety or even injury to someone would you want your phone number on there then? Probably not as your opening a whole can of worms.

If your flying in the middle of no-where then I guess put your phone number on.

...of course if you were responsible for any damage you'd do the decent grown-up thing and own up, wouldn't you? Or best not to put yourself in that situation in the first place

Actually I think even if you fly over houses it's pretty hard to land on something you can break or hurt anyway.
