Well, I think Trumpeter really took this tank's name to heart and was considerate enough to make building it an actual challenge.
Ejector marks are EVERYWHERE. I haven't seen it this bad EVER. It must be related to quality of the plastic, or timing of the ejection or ... I dunno, but it's terrible. Many are on the inside, which is fine, if they need to be anywhere, but why would you place 5 ejector pins on such small pieces?
It must have been an engineering challenge just to put so many ejector pins in one mould.
Luckily I starting using my own sprue goo recently, so at least we can try to work with this.
Sprue attachment points are very thick right up close to the part, so removing them is an exercise in patience and skill.
Locator tabs weren't a big priority in this kit. The boxes all around the turret simply do not fit, tabs or not. Most important thing to look out for is that at least the top and visible side fits somewhat nicely. The inside/underside can have a 2 mm gap for all I care, as long as it's not visible.
At multiple points during the build, I really couldn't see why some tiny parts are separate. It feels like most of them are only there to increase the part count.
The 16 hinges for the engine covers really needn't be separate. At least the 16 grab handles would require slide moulding, so I understand them being separate, but they sure are TINY and combined with the huge attachment points, hard to clean up and easy to break.
Hull halves also do not fit very nicely together, but with these big parts, the flex on the plastic will allow you to force them in place, and let the glue do it's magic.
Clamps and vices to the rescue!
The rearview-mirrors are a disaster. When installed, the turret can only turn with the main gun fully elevated. I'm assuming they are retractable on the real tank?
The thingies holding up the mirror are very thin and broke off when breathing in their vicinity. I tried re-inforcing with sprue goo, which worked fine, but I forgot to account for my clumsiness. I've removed both now. I may (or may not) add them back later with steel wire, but they'll probably bend or break later when used in the book closet anyway.
