RE: Hand-Eye Coordination
I started when I was 10, picked it up really quickly and was doing everything I wanted in no time. Hand eye coordination was amazing. Didn't have to think about maneuvers and just did them.
Now I am 37, have to think about the difficult maneuvers, not as steady as I used to be and still throw anything I fly through the wringer.
The younger you are, the better you are. Sometimes the games help, sometimes they don't. It depends on the kid.
All in all, get an instructor, you will have a good environment to learn in and crash less. Don't get one, you will get frusterated and quit 9 times out of 10.
