Been playing with the Tango Prime: Hangar set from FTM this week. I think it is a set with a lot of potential for us action figure folks, even if it is only 4" tall in its basic configuration. I'm attaching a pic of one module below. I've replaced the sliding hangar doors with a clear plastic wall, looking at using it as an entryway to a hotel or store or such.
The second and third pics are of the hangar wall section left flat in preparation for attaching to a sheet of foamcore or similar. In the second pic, the upright is made from a pair of the kit's basic buttresses, with one inverted atop the other, for a height of 9". The third pic has the kit's beam inserted between the two buttresses, creating a height of 15" - a rather massive wall, for sure! This is envisioned as a hangar wall or warehouse wall, primarily as a photo-backdrop. I have some ideas for a few dimensional elements, including a catwalk, that would protrude a bit, but essentially remain fairly flat.
One thing that concerns me - do you think the 1" grid-pattern is too "busy" here?
