I dropped out in the early 70s as well and I'd have to say that the size of new radio equipment impressed me a lot... and it is nice not to assemble one's own cannon plugs.

Considering inflation, it's amazing how cheap radios are now... in fact even not considering inflation it's amazing. Otherwise, planes have gotten more responsive and the building hobby has taken a big turn toward the dumper. I'm really glad I don't need kits to support my building habit, because the hobby industry sure seems to be turning away from them hard and fast.

The people have always been great and they still are, so for me that's one of the most important parts of r/c and it hasn't changed much at all.
