I'm just finishing rebuilding a Goldberg 77" Yak 54 my buddy crashed and gave me. The rudder on this thing is HUGE even for such a large plane. I know my buddy had some trouble getting the rudder to stop "fluttering". I guess it was more the tension on the piano wires on the pull-pull system. Regardless....this think requires a strong servo to controll its massive rudder. Could any of you guys suggest a good specific servo for me? I'm a futaba guy too,so I'd like to stick with futaba and I am on a tight budget so I need a good servo,but nothing overkill. I play around at 3D,but I'm no professional,so I dont need it to be perfect. I just dont want to kill the servo. So again,can anyone recommend a good futaba servo? There's so many,I dont know what to get.

The planes either going to have a GMS 1.20 in it,or an O.S. 1.60 if the 1.20 wont fly it.
