I first built small balsa gliders (including an F7F) in 1948. My first fuel-powered Control Line model was a "Little Mercury" with an OK .049 glow engine in 1950. I upgraded to a Fox .35 and built various C/L stunt and combat during the 50s.
I modified Sterling Ringmasters into "Wingmasters" for C/L Combat during the 50s. I built and flew C/L Dina Jet speed in the late 50s.
I raised a family from 1962-1980. In 1980, my first RC was a 2-channel ARF .049 Cessna 172. It was flown approximately 50 times with 25 crash landings with no assistance. I graduated to a Goldberg "eagle" and became a serious RC pilot, building and flying dozens of aircraft over 20 years, including a modified "twin piped .90 Super Hots" and a "Mong" unlimited racing biplane in the 90s.
