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 power that its set at. in milliwatts. to determine the maximum distance for output power.can I do this using Ohms-law to fine this out.or can any body explain this to me in the most simplest form that i could understand. CIRCUIT can be seen at http://www.elenco.com/manuals/rcc-7k.pdf. Can anybody who knows R/C Electronics HELP ME. THANKyou. PS Any help would be appreciated. newbie. JJ. :smiley16:
