RE: Does age have to do with what airplanes you fly?
I started flying at 11 and by 16 was teaching people twice my age to fly. I occasionally received the lectures by pilots that didn't know me. They would tell me "that plane is to advanced, fast, hard for you" that is until they saw me fly. My secret was not to immediatly show off, as this can make you seem reckless. Instead fly with precision and show you know how to handle your aircraft safely. You will soon win most over, and the ones that still think you are too young tend to be the ones that are irked by someone younger that has nicer/better A/C and more confidence/skills. Show you are safe and competent and "those that matter don't mind and those that mind don't matter" (Dr. Seuss.)
