Essentially, this kit is the same as the RevellAG 1/144 Boeing 747-400, except it is moulded in white.
Upon exmining the pre-assembled kit, I noticed that the tailcone area moulding is a bit incomplete around the APU exhaust outlet on one fuselage half. This is just on the kit I ordered, however; I received another from a friend without this discrepancy.
On one kit, I've done all but the landing gear, and it went together the same as the RevellAG 744 - fuse, wings and stabs cemented together easily. However, wing-to-fuse mating is a bitch. There is a plastic panel that goes on the underside of the fuse between the wings which contains the centre main landing gear wells. It doesn't fit properly (didn't on the RevellAG kit, either) so it requires a bit of putty and sanding after you cement it in place. Also, there are significant gaps between the lower wings and fuselage, necessitating more puttying and sanding. Same goes for the stabs - a significant gap along the bottom joint which I had to putty and sand.
The engines look good, even if they aren't the PWs they should be - nice detailing and the pylons mate seamlessly with the wings, although the fan hubs look a little small. As for the landing gear...I don't know why Revell insists on making turning wheels as the shafts on each of them are very delicate and snap off easily. I've had my BA 744 fully assembled for about a year and a half, and I've had to cement most of the wheels in place as they've broken off at one time or another. The Revell/Monogram 744 has the same set-up, of course. I think this time, I will assemble the gear separately and install them last on the one I currently have under construction!
Decals are reputed to be the best UAL livery available, according to Clinton Groves, owner of Airliners American/ATP in California. I haven't had the chance to paint or decal my model yet, but the ones provided with the kit are simple - United Airlines titles in grey, door outlines in white, cheatline stripe, and full UAL tail colours, including logo, all as one piece. The Revell/Monogram kit does not have the detailing decals of the RevellAG kit, however, which could be a drawback if you want the added markings.
This is a pretty good representation of the Boeing 747-400, certainly the best 747 currently on the market. The kit itself is a pretty good one, but not for modellers with little patience! It makes up into a spectacular model with a huge wingspan, so save a place for it on a wide shelf, out of the way of swinging arms, or else suspend it from the ceiling.
