Can anyone tell me what brands are compatable with which recievers, servos, transmitters etc...

Dude, way to broad of a question. There are simply too many combinations to cover all that. In general, servos are compatible with any receiver. Transmitters have two key "compatibility" issues, shift and encoding (PPM vs PCM, and PCM is vendor specific.) Assuming the shift and encoding is compatible, the TX can generally be used with the RX. This means there are many combinations of TX/RX, even cross vendor, that will work. But there are also many combinations that won't work. For a beginner, your best bet is to just get a radio bundle. Vendors will put together a transmitter, receiver, servos, battery, etc into one package, and it is often sold much cheaper than if you bought the parts separately. Obviously, everything is compatible in the package. If you already have equipment, if you can narrow your question to a specific transmitter, receiver and servos, myself or someone will post a answer for that combination.

Was trying to find out what vendor servos I could use with my 770 pcm reciever and my xp6102 jr transmitter. Or more so what servos will work with the next jr reciever I buy for my second plane as I got the servos for the one I am working on with the transmitter. Sorry for being too broad, I thought you were psychic or something I guess

Thanks

You can use virtually any servo with your JR receiver.
Futaba servos have a "J" connector. Cut off the little tab that makes the "J" and they plug right in.
Hitec servos either have "J" or "S" connectors. The "S" connector plugs right in, the "J" needs trimming.
Modern Airtronics servos have "Z" connectors which plug right in to your receiver. Old Airtronics were wired differently.

The above assumes you're looking at new stuff. If you're looking at ancient stuff there's no telling what kind of plugs you'll encounter or how they'll be wired.

You can use a mixture of servo brands in the same model. I had a non-BB Hitec on the throttle of my trainer and BB Futabas on the control surfaces.

cool, thanks a lot for the help carrellh. I was curious if I could buy cheaper different brand servos to hook up to my JR stuff for things like throttle servos and the like. Your answer was just what I needed. Thanks

You can use any brand servo you want, just pay attention to the wiring on the servo. On older Airtronics you need to shave off the alignement tabs on the top of the plug, but then you can use them with no problems as long as the wiring is correct. See attached diagram.

Hope this helps

Even better RCken, thanks.
