my first CL model was a COX P-40 that a neighbor gave me when i was about 9 years old. Dad and I promptly crashed it. Dad the bought a COX PT19 blue and yellow so we could train to fly. we flew all the COX products of the day, some real dogs. Dad bought a couple of Goldberg kits for me to build The Stuntman and the Swordsman. with these we were able to do good loops and inverted flights.
