This is a one of a kind center trailer fin design for either a 5th center fin or even a center trailer fin in a tri-fin setup. Loosen up that 5 fin or make your tri fin ride completely different. This unique FCS compatible fin has only one tab for versatility, slide it up to the front tab or keep in on the back tab for a bit more drive. Ultra thin foil section = less drag, more speed.
