Thanks. It still sort of drives me nuts that one of the most iconic aircraft of WWII is so poorly represented in 1/48th scale, even after decades of the hobby "maturing" into stuff like the recent XUNTONG IL-4 kit in quarter inch and the Zveda Su-2. Even if we go back a few years to the Trumpeter Wellington kits and further still to the Tamiya Lancaster we are still light years ahead of the Revell-Monogram B-17F and G kits.
I understand your sentiment regarding the lack of quadrimotors in recent decades, absurd, but I simply have to disagree with your assesment of the monogram B-17g. It is a lucky exception compared to the crap almost all the other bombers are, and I have seen excellent builds with little effort thanks to the squadron canopy. Without the squadron clear parts there would be a valid complaint still, but they are widely available and cheap.
The accuracy of the monogram b-17 outlines is extraordinary for the era, right down to the correct symmetrical wing airfoil so typical of the 1930s: the grossness of the more recent b17s in all scales is a a tribute to monogram excellence.
The Tamiya lancaster has no fuselage bottom flare and is wrong in an infinite number of ways. Monograms own b-29 and b-24s are unspeakable monstrosities as well.
The Wellington is a better trumpeter effort but unlike the old b-17 its canopy is way too shallow and wrong.
The xuton Il-4 is excellent but that is a rare exception, and the engraving is heavy enough to make monogram raised lines look good. The only land-based big WwII kit to be better than the mono B-17 is the ju-52 and the recent German bombers, and even for the latter they have more problems than the b-17....
The numerous AM sets for making the G really makes the later b-17s better served than just about any other large WWII type... G
