Kind of a side story...
In 1984 I went out to Las Vegas to watch the TOC.
Circus Hobbies was of course still going strong and while there I bought a JR Century 7 radio.
When I came home to Texas I took the "red eye" out...about 2:00 or 3:00 in the morning if I recall.
I decided to carry the radio on in it's original packing.
Even then there was security and they screened your carry on stuff.
The airline terminal was virtually empty as I placed the box on the belt.
The security guy kinda casually said, "what do have...a radio"?
I told him yes and asked him if he could see it clearly?
He told me to come around to the other side and see for myself.
Sure enough, in kind of an x-ray picture you could see the individual servos and wires going to the rx, the battery pack and the guts of the tx with the stick of nicads in it.
I was young and stupid then and I blurted out "It looks like a bomb"!
I immediately realized what I had said, looked around and of course every one within ear shot was staring at me.
The security guy just gave me a disgusted look and a "move on" jesture.
...simpler times back then...
