On the US side of things, you will need an N number. Reserve one right away, this can take some time to be assigned after the ship is de-registered in Canada. Then put it on the bird, 3" vinel is a good way to go. Armed with an N number, you can apply for US Registration. The ship will need an airworthiness inspection which may require a DAR (these guys don't work cheep)........ I went Experimental with an A&P inspection, then requested an airworthiness certificate from our local FSDO. All in all, not a big issue, but it may take some time to get everything accomplished.
