Hanger 9, Seagull and Vmar are not the same. For one thing, Hanger 9 ARFs are not made in Viet Nam. I've built all three and believe me the differences in quality are dramatic. As to the rest, Seagull and Vmar (and Pheonix) are made in Viet Nam and there are similarities, but Seagull is the better brand. The T-6 may be Seagull marketing Hanger 9 ARFs in other parts of the world, or maybe just that supplier using an available picture for their ad.
