My first radio was an F and M Quasar, which was totally built from a kit. Servos had about 30 parts to them and had to be individually assembled also. Servos were push pull rather than rotary. Parts for the cases were kind of hard to come by and when you looked at my set after a few months you would notice some red parts among all the blue. Forgot at this time what the name was for the red parts. We did not know as much as currently about the batteries and that cost me at least one airplane. Cycling did not exist. But it taught me how to fly and how to solder.
