FCSII AMT Twin Finner

This is the original template for the Merrick Twin Fin “MTF”, made by FCS to use with the FCSII fin system. The design, when hooked up with a small trailing center fin, makes a great loose feeling thruster. You get the speed of a twin-fin with the positive drive of a tri-fin. (Side fins are the same template as usedon the new CI Twin Fin)
