I've been reading a lot of these posts and I'm still a bit lost. Is there any Radio Basics websites or books that give a beginner an overview of all these complicated frequencie requirements and such.

I thought i was just gonna jump in but this is a bit of a study and i'd like to do it right

It is a lot of study ranch, but not because it's complicated, it's a lot of study because there is no concise reference. I'll see if I can give you a lowdown in less than a full page.
72MHZ is for flying, 75MHz is for ground, 50MHz is for either but you have to have an Amateur radio operator license to use it legally. Other frequencies are used for toys but that's pretty much it for serious work. You can buy transmitters and receivers from 3 channels to 12 (Most commonly 3-8)

The radio's send the position signals as 1-2 ms pulses of energy. 1 being far left, 2 being far right. Each pulse is sent one after another, channel 1 first, then 2 etc.. etc.. till the last channel then a frame pause is done (A pulse longer than any servo pulse could ever be) just to give the receiver an idea of where to start.

ALL new hardware follows these rules, older equipment may operate slightly differently (gold sticker requirement on older stuff) But if you buy it new that's it in a nutshell. EVERYTHING else is just how those signals are manipulated and used.

If you have any specific or general question feel free to ask, I love answering the more fundamental questions like how things work, and pretty much everyone else here will give you their opinion on what brand type or flavor of hardware works best for them.

I actually found a great "newbie" link

It covers quite a bit and it beginner friendly

Another good tutorial is at www.torreypinesgulls.org/Radios.htm

Cool Lynx, must admit I had my doubts starting to read your post if you could fit all the major caveats in four short paragraphs but you did.


And Ranch don,t be shy about asking here about the hundreds of small details.
