Hi Jim,
Impossible to top your involvement in the hobby! Congratulations and many thanks for your involvement in progressing innovation.
My involment is much more prosaic. Here in Australia (like most) I started with control line about 48 years ago progressing through models such as a "Taipan" trainer with a 2.5 cc diesel to a Nobbler with a fox 35. I still have the Nobbler

.
Started in RC in the seventies and could sort of fly a CG Falcon with a 35 OS. Then a hiatus with, surfing, marriage, children, etc. I returned to the Hobby about five years ago and now have a hanger that is all kits and models built from plans. I enjoy building as much as flying.
Current models ready to fly include CG Ultimate, CG Chipmunk, Dirty Birdi, DynaFlight PT19, Sputfire profile 3D and a self designed amalgam of a Contender/Chipmunk.
Cheers,
Colin
