You'll prolly settle on one servo. The 50cc Sukhoi should not need more than 200oz in on the rudder. It's a well balanced plane in the area of surface sizes and if it flys anything like the big one it will not require all the rudder to do everything you ask of it.

Tom,

Once I'm finally clear of here (Friday)I have to go over there. About a week after I get there I have to go over to somewhere else for about two days and then I go over yonder for a loooooog time it appears, untill I can eventually return here, then hopefully to there and complete some models. The big problem is I have to go from today to tomorrow on the same day, then I have to go from tomorrow to yesterday on the same day.
