I'm 53. I've learned more about flying model airplanes in the last 4 years, since I got back in and went to gas airplanes, then I did in all the years before. I'm a MUCH better pilot now. I still suck at 3D, but I love to try. It's exciting to learn something new! I get a great sense of accomplishment doing things that I couldn't do before. The two biggest thing to help me learn and get better were the sim and a good aerobatic gas airplane. I still have a long way to go to get to where I want to be, but I am getting better all the time. Would it have come easier to a younger me? Probably, but as long as I'm having fun, I can live with learning at a slower pace.
When I started flying in 1985 I can remember seeing the picture on the box for a Super Aeromaster. It was an Aeromaster flying knife edge under a limbo ribbon. I thought, "Man, someday I'd like to fly like that. I have the skill to do that now, just not the nads to get lower than 15' or so.
Late last fall I started flying Helicopters because it was something I always wanted to learn, just to say I can. I will never be a 3D heli pilot, those guys are just nuts,
but I really enjoy what I've learned so far and look forward to learning more.
At my old field we had a guy in his 70's that used to race Quickies and other things. The guy had the shakes, but as soon as he took off he was smooth as silk. It was pretty amazing
I may be a 53 year old on the outside, but I'm still a kid on the inside, and I'll keep it up as long as it's still fun and I can still do it.
