Aluminuminum, How delightful reading your childhood experiences. I had some similar experiences. I was a flying model plane builder. I still have my McCoy .19, Fox .35 and my OS Max .60. I grew up during the introduction of "go karts". I rebuilt an old Briggs "washing machine" engine and mounted it on an old push kart. If it made noise and smelled bad I liked it. (No, not my little brother!) And I made a Tesla coil for one of my science projects. Shocking, but no awards.
I have the interest, but I don't have the skills like you have. I can't cut a 2x4 square.
Working in factories during my career, we often spoke about the difficulty in finding young folks that can work with tools. Not very many young folks aspire to be diesel mechanics, welders, or plumbers. Good paying jobs all of them.
Air Forums is fun as there are many like minded people who enjoy the adventure of traveling like gypsies, and the mechanics of trailer maintenance and even rebuilds.
It's fun learning our childhood experiences were similar.
