Currently I'm 15, to be 16 in 2 months.
At 7 I built my first free-flight model (rubberband powered) and at 11 got my first R/C plane. Had 6 planes since then, although only 2 are still alive. Got another on the building board, my 7th, that I expect to be flying by 2 weeks time.
I got into 3D about 1 year ago, and I still regret why I didn't get into it earlier....
Also, 30% gassers are visible on the not so far horizon....
