I just received this kit straight from Japan, and I must say it's impressive. I haven't built a scale model in many years, but I just had to have this kit. I flew OV-10A's out of Sembach and Patrick in the early '80's, and I plan to build it in a standard configuration for one of those bases.
For the Sembach birds I'll need an unfinned 230 gallon drop tank. I'd like to put 4x LAU-68 launchers on it, but the kit only comes with 2. The downside of the Sembach configuration is that we never carried the guns.
For the Patrick configuration I can forgo the drop tank, install 2 rocket launchers, two guns in one sponson, and one practice bomb rack with practice bombs (not in the kit).
Either way I've got to wait for a weapons pack or look for something compatible.
