First was a Cox PT 19 my older brother and I owned. First flight was a wingover. I could barely keep it in the air and broke it a dozen or more times. A friend from school taught me to fly with his balsa slab model, i think a Goldberg kit, with a Cox .049. After that I built a bunch of those, then a Lil Satan, then moved up to the "big Iron" a Goldberg Voodoo with a Fox .36 I bought used for 5 bucks from a friend. I was hooked then on bigger motors, bigger planes and "more power" Then on to numerous Goldberg models like the Buster and Cosmic Wind. Still love the smell of Castor.
