It all depends on the size,type and weight of the model, but there are so many other factors like wing loading and the use of other aerofoils more suited to models,sometimes a scale section is totally unsuited to scale models as many have found out in the past.
A model is also more unstable due to its size in general and needs inherant stability built in such as washout at the wingtips to prevent a tip stall,especially on narrow wingtip shapes.
There are too many factors to say that a model will emulate its full sized counterpart,on the other hand types like world war one biplanes will fly in a very similar fashion to the original,it all depends on the design,in the case of the Shackleton I doubt whether it would fly as per the original,things needs careful consideration,that is why I say it is far from a beginners subject,you just build up to making a model like this from experience,having built three Lancasters I am still learning !
The only way to find out is to build one and see,using as many desirable features as possible to give the model a chance.
