One main battery for everything is IMO the best and safest installation.

Read the guidelines in this thread and especially in the first post: http://www.rcgroups.com/forums/showthread.php?t=1323951

http://www.bevrc.com/bev-wdr700-high...pal-p-171.html
120$

and..

http://hobbywireless.com/cart/index....roducts_id=394
115$

I will not spend more mony on the camera, but I am alwas willing to spend less if theres some cameras that is just as good as these... or even better...

Is it a bad idea to use main battery for all electronics in the plane? - even if I'm using a separate ubec?
A good inexpensive Panasonic GP-CX161 can be had for less than $20 here if your on a budget.

He does'nt support international shipping ... and I think I will go for a camera that has good resolution, even if its not that good ... It seems like that GP-CX161 camera is no better than a 60$ camera, so next step will be around 120$ ... I think, - actually with no experience

I think I will go for the camera at bevrc.com - because I will buy the 800mW 1.3gHz Vtx/rx there...

Is it true that not all cameras support OSD? - how do I find out if it supports OSD or not?

You are really helpful here I like it! - thaks!

In some cameras you can adjust its settings such as white balance etc. This is done using an OSD within the camera and has nothing to do with the FPV OSDs such as RVOSD, DOSD+, ET OSD PRO etc. You can of course use a camera that doesn't support OSD to a FPV OSD.

the big difference is in the actual quality of the camera and the connectors

there is a difference and you do get what you pay for

Wiring Basics.

For all of our electrical systems, there are three basic connections:
  1. Ground - Think of this as the electrical "foundation". In general, it is common to anything electrical in our systems.
  2. Power - Think of this as the "Fuel" to that device
  3. Signal - Think of this as what the device inputs, outputs or both. The number of Signals into or out of the device's can vary from zero to ???.

Some examples:
A light bulb has ground and power.
A servo has ground, power, signal in.
A camera has ground power, video out.
A mic has ground, power, audio out.
A VTx has ground, power, Video in, Audio in.

Wiring colors vary though you can be 99.9% sure that Ground is BLACK(sometime brown), Power is RED.

Very nice idea an document !

I'd suggest some small changes/additions :

-Could be useful to add a glossary of all terms (and common abbreviations)

-"Having a prop out in front isn’t necessarily a bad thing. When night flying the prop disappears anyway."

Well, at night everything disappears more seriously, I think night flying is not something to evoke in this document if it's aimed for beginners.

-"For some, seeing the spinning prop gives a more realistic feel to the plane. It also is necessary for flying gliders where the prop opens up and takes up much of the video screen."

Can be a little confusing for a beginner to talk about the propeller of a glider, he might not get that it's a motorized glider.

-"You need to build a system to suit your personal goals. This is why this is a do-it-yourselfer’s paradise."
As that section talks about video TX systems, it can be good to add a remark about some legal aspects (the authorized frequencies varies by country, remember that your video signal can disappear for many reasons, etc)

- you mention several distance 'records', but I would say it's not the best place to do it, maybe just give them as examples. (I mean or you should add the record claimed by Trappy here http://www.rcgroups.com/forums/showthread.php?t=1326375 then it's a discussion about what is a record, how to prove it etc)

-"The cameras are basic CCD cameras."
CCD or CMOS, for example the dx201 and gopro are cmos.

-in the camera section, buy a ntsc or pal according to the user's country, mention that transmitters and receivers will work with both but some tv sets or video recorders will only work with one type

Excellent work so far !

Here is an interesting statistic

3 of the 4 guys who have flown the furthest long range on rc groups, use stock antennas on their video tx's

so in order to get perfectly clear video, even at long range over 23 km away, there is really no reason to make up a do it yourself antenna

however all of them use after market video rx antennas and lawmate video rx's

and all of them use uhf for rc control

sometimes statistics don't lie

This is a problem
we are seen all sorts of inputs, ideas,recommendations,specific questions,electricity questions etc etc.

One document can deal with this, but it will end up the size of the Encyclopaedia Britannica.
Even if this thread is a sticky, all the information will get lost in a techno babble cloud.
There was a similar thread for newcomers about what to buy,but it has lost its appeal long time ago and this thread may go the same way.

So... I recommend creating a website where all newcomers could be redirected.
It might be organised into specific chapters, from safety aspects to wiring specifics, and, could have different levels of involvement.

A website could be really dynamic too if well maintained.
unfortunately I don't have a clue on how to make a website and I can see this as a herculean task if made by one person alone, so there would have to be different web masters covering different disciplines.

For example :
-IB could be the aerial specialist
-Daemon the video specialist
-Trappy the safety specialist (sounds weird for some but he knows how to make a system safe)
-Crist Rigotti the applications guru
-David22 the glider and aerodynamics consultant

(just to mention a few) etc etc...

Then, when a newbie asks question about the best setup for 27km flights using a parkzone vapor, he could be directed to the "in your dreams" section of the website.

the different web masters could cut and paste ideas or discussions from ordinary members of RCgroups in this particular thread.

The thing is there is such a massive amount of experiences to collect that it would be a massive job in its own right.

Did someone mention a wiki link before? is this the same sort of thing?

Maybe you don't need to get so in depth, afterall... I had a read over the guide last night....it's exactly as it's called. A guide. Not a one-stop-shop for all things FPV/RC. From my understanding, noobs/beginners can read it and get started and up to speed on the subject. They can then go off and complete their own research on the subjects you're wanting to know more about, after learning the terminology and basics.

That's how I've interpreted it anyway....and it does a fine job at that.

You could be setting yourself up for failure if it's too in depth. That's my 2c anyhoo...

Keep up the good work IBC..Your efforts are definitely not going unrecognised!

I think it's good especially now that it's a sticky. There's plenty more in the forum to read but I agree that your suggestion should be included if it not already is. That being that lurking and reading the forum is one of the best way of learning.

Congratulations for the great guide but I have a question...

You speak about VSN500 camera http://usasecuritysystems.com/produc...VSN500NHB.html as a great product and then "but requires a filter if using a GPS".

Ok, I ask you.. What's a filter for GPS ? Why do I use it and where can I find ?


Thanks
Matteo

You need to coil the wire around a ferrite ring several times.

This is a ferrite ring: http://www.dpcav.com/xcart/product.p...5&cat=0&page=1

This is how to coil it up: http://www.dpcav.com/xcart/product.p...0&cat=0&page=1
