I don't know how the Rippled PVC compares to the Canadian pipe. But I do know it is quite a bit lighter and thinner than the American square gutter pipe. I have built and flown what I call the Spadistar, I cloned my trusty Avistar and used rhe rippled gutter pipe and built in the same fashion as the Spadet.
