Control deflections.
kyrcnewbie,
I just looked on the Tower Hobbies web sight and found the SuperStar 40 manual.
Here is what I found listed for control throws:
Elevator 1/2" up 1/2" down
Rudder 1" left 1" right
Ailerons 7/16" up 7/16" down
So your 1/2" each way is right on the nose.
Hope this helps,
