I am scratch building a 96" span plane. I need to know what the deal is with the inline servos for the rudder. I am seeing this alot in pictures. Is it for more torque? Do you need that much power for these kind of planes. I was going to just put one standerd size servo in the fuse under the elevator to control the rudder. But I dont know if that is going to be enough. This is my first one of this kind, so I am just learning the new stuff.
