Guide to RC?
Where can I find out where to make a simple 2-4 channel RC thingermabob with a range of about 50 feet? I just don't get it, everywhere I look, they make these huge units. My helicopter is 6 channels and the circuit board is no bigger than 2x2, and only has 2 IC's on it. Why can't I find instructions for some small and simple like the circuits you find in RC car! What about Zip Zaps! Their circuit boards are tiny, and work better then the huge circuits you find online!
