Thanks Jester, I thought the suggested throws listed in the manual were high like something you would see on a 3D plane. I cut the suggested throws down by 30% to start with and I'll add the suggested 20% expo. I'm running a DX7 radio. Good news is shes done with the floats finally finished and ready to fly. I don't know how others hook up they're float rudder but I didn't like the cable sleeve method and I didn't want to drill hole in the side of the fuse to hold the cable sleeve's so I went out on a limb and mounted a water proof servo in my float just ahead of the rudder then wired it with a quick plug.
