You forgot 1/6, 1/18 and 1/35.
Nothing more frustrating when you are collecting something in one scale and they go and change the scale on the next release.
I really like the BIG engine kits (?) by Liberty ( Hawk, Revell and any one else that has done these kits) but when they switched scales on their HEMI kits I was at a loss. The last kit, one that I was really waiting for, the 990 Super Stock version, comes out in 1/4 scale not 1/6 like all the rest.
Oh yeah, first off , why 1/6 when there are so many vehicle kits in 1/8 that they would fit in ?
