An Italeri OH-58 Kiowa Scout helicopter in 1/72 scale. I gave it a base made from an old CD on which I glued a GW flight-base and 5.5" of clear plastic rod, covered everything with PVA glue and sand, painted it and added some flock - done!
BTW, the .50cal MG pod is completely scratchbuilt. I have another base of the same sort as there are more air units to come.
