ex-mil
Apparently you can register ex-mil aircraft, VH- but they are "Experimental" cat. There's a few getting about, couple of kiowa'a. . i know of a company who are selling a white kiowa. .there's also a UH-1 (or similar) for sale.
I think a while back a couple of company's were selling kiowa's, one ex canadian mil. Cheap to buy, but you can only use them in the "Exp Cat"
