Yes indeed, T.B. and Max are on point. I was about 7 or 8 when I built my first model, can't recall just what it was, but it had swept wings, large tip tanks, looked like a Lockheed design. The time period was about 68 years ago, I'm closing the gap on age 76. Tube glue was probably all over the model, me and anything nearby, but it was something sensational for me to build and enjoy. No paint or decals, my imagination didn't need them.
Then came flying models, at first they were die cut sheet balsa, colors printed on. A few years later came the old school stick and tissue models, the real fun. By about 10 or 12 came the realization, that the complication of building accuracy and following the detailed instructions, was a really enjoyable process for me. I believe that followed through for me later in life, knowing that carefully reading and studying the plans, instructions and kit materials, led to a better finished product. Same in life and work, attention to details, patience and discipline, do actually have a positive return.
These many years later I'm still at it, scale balsa free flight and plastic aircraft, I enjoy it as much today as I did back then. A great hobby, I don't keep them, I give them away to neighbor kids. It has gotten many of them to take up the hobby, I hope they will also pass the skills along to others.
