I'll take it one step farther, one of the biggest mistakes I see with people setting up their planes for precision flight is using way too much throw. The idea for a precision set up is to always use that absolute minimum amount of throw necessary to achieve the desired flight performance. You will be amazed at how much better the plane flies and how little throw is actually needed.

I let one of our local 3D wizards fly my Extra, set up only for precision. He was absolutely amazed at how smooth it flew and yet how capable it was. 3D throws are really only needed for 3D.
