Maybe some people really do enjoy flying in a way others would call "timid", I suppose, and, hey, power to them, it's their $15, it's their relaxation, they can do whatever they like, I'm not going to give them a mouthful about it...
That said though, I have to wonder, if at least some of the people who fly "timid" are not doing it so much because they enjoy it, as because they feel that they cannot beat a certain plane , or situation, in the plane they are in.
The obvious observement is that, yep, you can't beat that plane, or that situation, if you never try to and figure out what works and what doesn't.
But if they would try, man, they might just suprise themselves. I know I have.
I just wish that someone who says "I'm in a Mustang.... I'd better not get close to that P-38" would take a look at Flyboy's film in the help & training section... That was a really great film of how it's possible to beat a 38 close in with a Mustang. He didn't beat a bad pilot, either, he beat Rocky, and Rocky's not too bad at all.
Again, if it's your cup of tea to fly "timid", by all means, enjoy. I'm not going to tell you not to (heck, what's it matter to me? Your in my fight a whole 2-3 seconds out of every minute, whatever). Still, if you'd like to not fly so timidly, yet are concerned of "failure" just remember, you get a new plane if you die, so by all means, push yourself, and pay attention. Eventually you'll do well.
