JRoque, thanks a lot for answering my reply. that's not waht i was looking for, i was not very especific. i am trying to build a very, very simple mini rc car, that works. then i was thinkin about adding stuff to make it better, because i've never builted one. i have to start with the simpliest project i can find. im not very good with projecting circuits. I was hoping someone wood help. i stoped looking for transmitter and receiver schematics because i'ts very confusing, so i'm thinking about buying a kit, allthough i wanted to be sure i cood built it and not wasting time and monney. all the best...
