Further investigation today. I suspect the guy who assembled it was on piece work as there are some minor bits missing off the bridge, and there are two holes under the breakwater in the foredeck for screws which are not fitted. There are quite a lot of sprue marks which need removing. The stabilisers have reinforcing gussets which hang out in the water flow, and the shaft exits are extremely unstreamlined. The two main turrets and the helicopter flap about and need securing propery - the latter though looks a bit out of scale and may be sacrificed to save weight.The aft deck has large "jelly" bungs over the screw holes.The boat weighs 1,395g, Bow 675 and stern 733, so I can get the balance right after modification. (I know they don't add up but so long as I support it in the same places the proportions will be right.) Since the battery only weighs 114g, either the motors are very heavy or there may, with luck, be some ballast which can be reduced to compensate for any additions. Some of the superstructure, for example the silver deck on the switch cover, is held together with steel screws, so there is a weight saving high up when they are replaced with glue. I have done a full "field strip" - switch cover and battery housing, and will delve further after sea trials, which are now unlikely to take place until next week. It may well be that this further investigation will show that it's not worth going any further, but wth. Interestingly, the picture on the box is very true to the model, so it's easy to see which bits are missing. The silver bits are not as glaringly chrome as they look in most pictures, but the dark green missile tubes and boats do look weird. I'm pretty sure that the photo Martin posted was of the Trumpeter kit, as the missiles are showing in the launchers, but on the toy the tubes are closed, and there are no signs of screw holes in the fore deck. I'll try to send photos later, but may have to send them to Martin and see if he can put them in. Now off to try the resizing exercise!
