What's THE BEST 1/72 KA-6D Tank Intruder around???

Fujimi's is the better of the two, detail-wise. However Italeri gives you a wing-fold option with basic detail.

Watch out for Fujimi's Intruders. They give you separate leading-edge slats and invite you to install them in the dropped position. However, the slats dropped at the same time as the trailing-edge flaps, so they would have to be dropped as well, and of course, the flaps are not provided separately. Grrrrr.

I have the Italeri 1/72 KA-6D and the parts are crisp and the details excellent. I have not assembled my kit for fear of spoiling it. I don't know about the fit.

Italeri also has KA-6D in 72nd scale. Don't know anything about quality, but You could search for in-box or build previews on the net.

I think fujimi makes the only KA-6D. Very fine recessed details. Don't know of the fit as I haven't built it yet. Better than Hasegawa's A-6 offerings.
