Welcome to the forum, Josh. There are several excellent modelling publications out there, they each have their own individual style and target audience. Assuming you live in the UK, you should be able to pick up any/most of these from WHSmiths or suchlike. In no particular order, and my own personal viewpoints (YMMV):-
Scale Aviation Modeller International (SAMI): Aircraft modelling only, packed with news, reviews (kits, aftermarket, decals, books) and build articles, less emphasis on actual reference material although it does usually include profiles and/or plans for one specific aircraft. Written in a friendly and informal style.
Airfix Model World (AMW): despite its name it's not actually published by Airfix, although there's obviously an affiliation. However there are usually only one or two Airfix article subjects, but the rest are from other manufacturers so much less partisan than you might imagine. High quality and covers all genres – planes, cars, armour, figures etc – with good reference material to back up the featured build subject. Some aftermarket and book reviews.
Tamiya Model Magazine International (TMMI): same comments apply as regards AMW – it's got Tamiya in the title but covers models from many manufacturers, and is fair and unbiased in its appraisal of such. Also multi-genre. Personally I find TMMI aspirational, full of superbly built and photographed models that I want to emulate, with perhaps less emphasis on techniques than some other mags.
Model Airplane International (MAI): by the same publishers as TMMI and a similar format, but aircraft only. There are often colour profiles of a main subject, but like TMMI the attraction is the superb builds. Step-by-step construction photos are a big part of the magazine.
There are several others too, those are just the ones that I tend to read because I can find them fairly easily here in Canada. Also all of the above are available as digital editions for iPad/iPhone etc so they can be downloaded and don't take up cabinet space in your model room.
