cybertron Posted April 10, 2005 Report Share Posted April 10, 2005 Hi all: I just bought a R/C car kit to build and to learn about how they function. I been trying to find out in the output power stage of the amplifier Q2 in the circuit schematic. What is the output powerthat its set at. In milliwatts. to determine the maximum distance or range for output power, can I do this using OHMS-LAW to find this out,Or can anybody explain this to me in the most simplest form that i could uderstand. At this time i cannot post this schematic. BUT. the circuit can be SEEN at www.elenco.com/manuals/rcc-7k.pdf.. Can anybody who knows R/C Electronics HELP ME.. THANK you. PS any help would be apprecited... JJ. Quote Link to comment Share on other sites More sharing options...
cybertron Posted April 10, 2005 Author Report Share Posted April 10, 2005 Hi All: I been try to find a supplier for the TX2C And RX2C ICs. These are R/C toy car remote controller integrated chips. they are used in R/C cars brand names like nikko, radio shack, Bright lite , ect ect.. also been try to find there datasheets. does anybody know a website where i could get the TX2C and RX2C Datasheets. (Second Question). The TX2C chip thats in the r/c transmitter controller on pin-12osci and on pin-11osco I like to know the internal oscillator is set with a 200k ohm resistor and why they used 200k resistor and not a high or low resistor can you explain this to me that i could understand it. I can't post the circuit at this time. BUT you can see it at this site www.elenco.com/manuals/rcc-7k.pdf.. Can anybody who knows about R/C Electronics HELP ME. THANK YOU . Any help would be very Apprecited... :-[ Quote Link to comment Share on other sites More sharing options...
audioguru Posted April 10, 2005 Report Share Posted April 10, 2005 Your link doesn't work. By shortening it, I got to Elenco's website and found the manual.If you try to increase the RF output power, it might melt Q2 and might be illegal because it would cause interference to other RF. :'( Quote Link to comment Share on other sites More sharing options...
MP Posted April 10, 2005 Report Share Posted April 10, 2005 Have you looked on the www.rfdigital.com website? They have several different types of these dedicated chips and their respective data sheets.MP Quote Link to comment Share on other sites More sharing options...
