RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Vintage Radio Control Systems

A lot has changed in radio control since I purchased my first system sometime around 1974. It was a used, 3-channel OS Digital system. The servos jittered to beat all, and the range was lucky to go as far as 1,000 feet. It was sent back to the factory for re-tuning and check-up two or three times, and it came back the same every time. In that day, all the transmitters and receivers had metal cases -and it's a good thing because one time I sent the transmitter on the top of my friend's 1965 Mustang while loading the plan into the car, then forgot about it until I saw it hit the road while looking in the side mirror. It had a couple scratches, but worked as poorly as ever.

While looking back at some of the editions of American Aircraft Modeler from the time I first joined the Academy of Model Aviation (AMA), I ran across a lot of familiar old advertisements. As with almost all other things electronics, the quality has obviously gotten better while prices remain the same or drop. It's been a good ride for modelers. In trying to find some of the old ads online, I could not locate any, so what the heck - I scanned some of the pages and put them here. I think all of the companies are out of business now (except Futaba). A lot of these RC systems can still be bought on eBay.

Please visit my Airplanes and Rockets website for much more modeling articles and information.
