Those circuits and the bandwidth they occupy are illegal now. Bandwidth for Radio Control was changed a couple years back to support cellphones, pagers, gps, ham radio, etc.
Secondly, building your own would probably cost you 3 times as much as purchasing a certified system. My advice: forget building, go buy one!

korean rc transmitter

Hello i'm a newbie here and sorry for my bad english, i'm from indonesia. I've seen the r/c circuit for tx2b/rx2b on the pdf document from

**broken link removed**

See the typical application circuit section.

My question is, Do the images of the tx/rx circuits show that between encoder/decoder and rf circuit are different?-I mean both are in separated usage. If yes, can i modify rf circuit to enlarge its range frecuency,but it won't disturb the function of the encoder?
Thanks.

Just get Holtek HT12E encoder and HT12D decoder ic's just rig it over a vero board.
Here are the schematics. Also readymade assembled and tested kit for 4 channel remote with HT!2 is available at "www.united77.com"
