1/2 A Profiles are cool.
After I managed to destroy my Cox PT19 on a freak nosed dive encounter with the patio... using the Babe Bee from it, it fell to a "Beginners Ringmaster" to FINALLY teach me how to fly C/L waaaay back in the mid 1960s.
From my "Beginners Ringmaster" I moved to a Goldberg "Stuntman 23", then a "Baby Ringmaster" (built up wing), and eventually built a "Lil' Toot" as well (but don't recall ever flying it). There may have been other 1/2 A profiles that I built... but those are the ones I distinctly recall.
However... the REAL 1/2 A "memory machine" for me is the "Combat Kitten": My first "combat wing". I couldn't wait until I was comfortable enough flying the profiles so I could finally build and fly a "combat wing" airplane. Those "evil looking" combat planes had me from the time I first laid eyes upon one. (A magazine ad.) That time came, and onto it went a Golden Bee. Wow! What a difference between my profiles and that Kitten! Fun!
Wow... that was sooooo long ago now.
Fortunately, when I fire up one of my Fox X powered combat planes and give the helper the "go" signal... I'm a kid all over again!
Time machines, they are.
