Here is his neat way to make a full-flying rudder:
Hearing all the great ideas on LightSticks, I thought I would offer my mod. I was less than impressed with the turning response on my stock LS. I added dihedral with a string, and while better, it was still weak, the rudder was nonexistent once the throttle was cut, which makes landing interesting so I decided to try to make the whole vertical stab move.
On my second build, I cut off the rudder's bottom mounting tab then drilled a small hole vertically into the bottom of the unhinged rudder about 1/3 of the way back from the front and mounted a carbon rod into the rudder, pointing down and leaving about .75" out the bottom. Then I drilled the rear of the stick and glued in a 1" long aluminum tube for a pivot for the ruder.
The control horn should be mounted just to the rear of the carbon rod. I used a piece of one of the plastic collars they give in the kit to hold the rudder off the stick a little to give it clearance. I used another of the extra collars over the bottom of the carbon rod to hold it in place.
With this mod, the response is much faster and I can fly in tighter spaces. I have turned the throw down from 125% of normal to 85% on my radio, and it still turns better than before, less drag too. It even turns with the motor off, although still slowly.

The pivot should be just forward of 25% MAC (Mean Aerodynamic Chord) because it will minimize the load on servo. If you put it aft of 25%, the surface will tend to go to one extreme or the other.
