i would suggest 45's inside the port as well as round over on the port mouth (or kerfed) and inside port wall (where it turns 360) t-nuts for the inverted mount...... um, some folks might disagree with the dual slot ports, stating the surface friction will be greater than a single.... thought any on aeros, less port area will be needed, thus less displacement within vb. i dont remember if you compete any, this is just daily driver and demos, right? if it is carried through as your other build was, same quality, i am sure it will look great! did you leave any room in the trunk for other gear? lol how can i get a image og the xcon like that? i want to get the 3/4 profile view for a tattoo .... looking good so far.... oh, what is your bracing going to consist of? 3/4" all-thread, when used right, can add alot of strength and not displace alot of air, imo. gl w/ ur build ! chop
