Try 1/350 naval aircraft, a pair of wire clippers, and a sharp knife!
From left to right, a Planetlifter, a SuperPelican, a Corsair II MSF (custom), Inseki HSF, Angel LSF, and another Corsair II.
Here's another shot giving size against minis:
(The paintjob is for a canon unit I'm working up at the moment)
These all came from two Tamiya 1/350 USN packs, but there's a lovely company called Trumpeter, who'll sell you six packs of planes (or helos) for around $10US. They're great sizes for on the map; okay, the PlanetLifter looks a little small next to the MW:DA infantry, but it's good enough!
I'll leave it to folks to guess what the feedstock was. And yes, I note the Planetlifter has lost a tailplane due to flak ... ;)
