While I think there are issues with the QRF Challenger 2's turret (see Castle of steel and Dorchester, part 1: QRF Challenger 2A1 review), it is a nice model which can make a relatively convincing rendition of an Op Telic tank.
Now just to put this statement in context, there was a time when I would whip out my ruler to check that a model was scaled correctly and refer to scale drawings to check that important detail wasn't omitted. And then bitch about it if there were errors. The trouble is that, unless they are drawn by very committed people who spend their time clambering all over museum exhibits, scale drawings are mostly one person's interpretation of what some piece of machinery looks like.
In light of this, I've converted to the philosphy of TLAR. I'm happy to fiddle with toys until I reach the point of This Looks About Right (though I will refer to as many photographs as possible to determine what looks right to me). If the US Army could get away with fiberglass VISMOD to make a Sheridan look somewhat like a T-72, I can surely get by with plasticard, filler and a file.
The turret was the one item which required the most work and although the result is far from satisfactory I reckon it looks somewhat more like a Challenger 2 turret than it did out-of-the-bag.
