Question Regarding Online Play

Hello,
Big fan of CFS3 but I've just recently started online play. This may be old news so forgive me if it is, but has anybody else out there played against planes that appear to defy the laws of physics?
For example, the Spit (which can already turn on a dime) turn on a penny? And how about planes that skip across the ground? Not sure if a bug is involved or dare I say a little modification....I've read a couple of posts about the erratic stalling of the Stang and how to "fix" it in the cfg file. Is this done for online play? Isn't it cheating? 
Off we go into the wild blue yonder.....
