Some random thoughts:
I was born in 68, and read Fifties Air Trails same as you!
I built a flew a trixter pixy, too bad, I had a case of them a few years ago, you missed out!
Check out the Super Cub in my gallery, it's another Andrews/Guillows kit, from the same series as the trixter pixy...
Summer camp(in the seventies) did a TON of modelling, we did all the guillows rubber jobs, plus all the great Goldberg 1/2a CL jobs...and rockets...LOTS of rockets...
