Is it normal for first timers to show up with excessive throws on all their surfaces (controls)? Yes very common but what you have going on there is not simple throw adjustment.. The problem is agine due to some poor decisions and an awful servo/linkage installation.

Due to the offset servo to avoid the center rib it now will introduce aileron differential almost no matter what you do. In other words one side will never match the other as well a going more in on direction than the opposite direction. One band aid that some have used that will help some but agine not properly fix the problem is to simply angle the servo are at neutral ninety degrees to the pushrods.

Now the right way to fix it is to move that servo over to the center. Cut out that center rib and move it over to where it will operate as intended. And no there is no problem cutting that center rib out and it provides virtually no bending load strength.

Also such a long servo arm is not necessary. Now if the torque rods are excessively loose inside the trailing edge this can cause slop and sometime insufficient throw.
