I use a pullpull linkage from the rudder horns, attached with fishing swivel snaps. Forward to the strut at the fuselage, through a dubro 2-56 screw-eye, down to the top of the float and another 2-56 screw-eye, and back to the water rudder. I use bronze springs on each cable at the water rudder, and an ERNST water rudder. When I want to take off the floats, unsnap the 2 swivel-snaps, and the cable stays with the floats. 4 screws hold the floats to the plane, and 2 of those are used to hold the lg on. I usually replace the other 2 just so I know where they are.
