From plan to plane

[Mauri]

Hi there,

Let's say I have a 3d view of a real plane which I would like to build in scale.
Should I use the exact measurements down to the scale I want or are there any minor changes I should do here and there so my model will fly better? I have read that some people enlarge rudder, horizontal stabs or wings ... but how can I know what to change and how big the change has to be? How can I take does decisions in the benefit of better flight? :confused:
Any help would be highly appreciated ...

Thanks to all who take the patience to answer to newbies like myslef! :p
Cheers from Spain.
