I build both aircraft and armor, since I consider myself a "Military Modeler", rather than an "Aircraft" or "Armor" modeler..
I use both PE and resin parts, I just don't buy them very often...
I don't buy AM track or PE parts for armor, it's more fun for me to cast resin parts that are in one kit, and use them on another, ie, that engine on the P-61.. I've cast about a dozen copies of it for use on other aircraft that used the P&W R-2800 radial.. I cast copies of Mongram figures, since they're just flat the the best 1/48 figures around, IMNSHO...
As far as my "old-school" appraoch t' modeling, it's the same no matter the genre...
As a "Gizmologist", I don't strive for "duplication", but rather 'suggestion"... When you look into the stuff I build, be it a turret or cockpit, it's not nut for nut, bolt for bolt, it's just prety "busy" in there.. Gizmology, howerver, is not a license to produce unlikley parts and /or stowage out of thin air, it has to be close to the original part, just not an exact copy... There's a radio in that Stuke I built, but even so, you can;t read the freq numbers, and you can see the breech on my M109A3, but youcan't see the firing-lock or the inside thread for the obturating spindle.. And if you can't see it, I don't bother building it...
However, I digress...
The tread-heads are a different lot, but it's just that they talk in a strange language to aircraft modelers, stuff about sponsons, glacis plates, bore evacuators, muzzle-brakes, cupolas, the coax, matching units, and final drives is all... They don't talk in plain language of aircraft models like, fuselage, empenage, cowl-flaps, Nordens, throttle-quadrants, dihedral, or dive-brakes, prop-hubs and spinners...
