I'm definately of the school that "If it looks like a Spitfire/Heinkel/Zero/Whatever then its good enough for me.
Although I have been known to get a bit rivet counterish with my P-47s

Thats more down to a case of wanting to make the most accurate representation of a chosen aircraft as possible at the time and with the information available.
The only person that really matters when building a model is the individual modeller, and he or she can determine the level of accuracy/detail to be aimed for dependant on many factors.
I have read threads absolutely slating models ( some that havent even been released yet),but dont see photos of many models from these armchair reviewers.
A classic example was the Dragon 1:32nd Mustang released a couple of years ago that many of these people said was "unbuildable" due to inaccuracies. A blogged build of the same kit on this site produced a stunning finished model.
Build what pleases you, to the level of detail that pleases you, and to the best of your ability at the time.
If you follow these three basic guidelines you'll enjoy modelling, produce models you enjoy looking at in future, and find yourself improving with every build.
Did I mention that you'll enjoy it?
Mentioning no names but it wouldnt happen to be the site where the "Numero Uno" has posted twice in the last few days telling people to play nicely or he'll take their ball away?
Enjoy the F-117!
