Nice, but I plan to us them, plus some ex-Dwarf now CSA and USN gyrocopters and ornithopters, a ships and a catamaran zeppelin to fight an air/sea battle with different altitudes. I've got 12 sets of wings, one set of wings of another kind, four ornithopters, a gyrocopter, the ships, and the parts for the zeppelin. Only one ornithopter is ready to go, the rest all need work, but before I start I want to be sure I have everything I need.
Yes I know, that's a lot of work and I'll probably never get it done. But still it is a neat idea.
