my grandfather (who raised me) built R/C planes, and went to airshows. There's a picture of me at about 3, at KCRQ sitting up against the wheel of a p-40. It was always our saturday thing to go to the airport and airplane watch, or out to MCAS Camp Pendleton to fly the R/C planes (he was a member of the R/C club on base). He designed a few award winners in the local model airplane club. I knew about dihedral and camber and all of that by the time i was 10. By the time i got my certificate, it was too late, he was too big, and too far gone mentally to get in the plane with me. I miss those days
