You mean the rudder servo? yes it is a huge surface and it would be wise to put a high torque servo.
As far as the radio is it posible to mix elev with some auxiliary channel and mach them?
cj, with the 6102 you will need the extra channel for the ailerons so you can utilize the flaperons and spoileons,(the little switch on the top inside left will also give variable flaps)
to hook up the dual elevators you will need a servo reverser and they will be fine.
