Never got into Airfix kits, always preferred the balsa wood and paper versions, I started with Keilkraft, 2s6d old money per kit. My first was a Stinson. By the time the 'extras' like dope etc. had been purchased it was a 5/- kit!
Progressed to a Jetex 50 power plant, built a beautiful Gloster Javelin, launched from parent upstairs bedroom window, straight up in the air, caught fire, (I had no asbestos paper, as required by instructions), crashed and burned!
Went back to Tow Line gliders after that.
