I can't say for certain on the planes, but I seriously doubt that the improved 688's (the ones with the VLS) have that type of plane. They might, but I suspect they don't. What I am just about certain of is that the placement of the tubes in the model is incorrect. I don't think that any boat in the class had them arranged the way the kit does them. Seems like a simple thing for the kitmaker to get right, but whatever.
One other thing my son pointed out was that not only do you need to use the "alternate" cap provided on the infamous sprue "D", if you're doing an improved 688 (scope placement etc), but the shape they provided for both the sail and the top are wrong! (LMAO!!)
The sail is much more "blunt" on the forward end, not tapered exactly like the back. And as you look at it from the side, it is much "flatter" from front to back, with nowhere nearly as much "crown" as the kit has.
Putty, fill, sand, repeat!!!
ANYWAY, I scratch built one additional mast (they only give you three and there should be 4 in addition to the snorkel), and drilled out the opening in the forward end where the bridge is. And I've added one small brass rod just behind the bridge and ahead of the masts for the navigation mast. I also hand painted the camo, because I figured that would take LESS time and effort than fooling with the decals, and I also had one additonal scope that the kit wouldn't have had decals for.
Finished the initial two coats of black on the hull, and my next step is the hull red on the bottom. The Tamiya "Hull Red" is too brown, and I mixed a small sample last night of 1 part Hull Red to 1 part Flat Red, and my son says it looks about right. It isn't a bright red, but it isn't as brown as the "hull red" color.
Based on my son's input, I'll make the entire lower half that color, using the exact "center" of the hull (rather than the "waterline") as the dividing line. One note: that will put the entire counter measures pod in the red section. My son tells me that the top surface of that would be black. Makes sense when you look directly down on the model from the top in a plan view. Sort of the same concept as painting aircraft wings.
I'll try and do some more photos in the next couple of days.
Getting close now!!
