Bill,

These are just my opinions so take them with a grain of salt.

Rudder trim is not worth the effort.  I have a tab on my rudder but I have never had to adjust it.  If you do need to adjust it it will probably only once.  That is why just a tab works on so many planes.  You could probably just "miss rig" the rudder when centered to center the ball. 

The aileron trim on my 360 is just a hinged tab 3/4" by about 5".  To test how well it worked I flew the plane as unbalanced as I could get it.  No fuel in the right tank, left tank full, 200" pilot.  It only took about 1/2 the travel to level the wings.  Most of the time I only move the tab a very small amout.  If I need to fly for a long distance with wings level I use the autopilot.

The aileron tab you are talking about is too big to start with.  Trying to make it like the elevator tab is a nice idea but I think you will find that the size and shape of the aileron will make the job dificult at best.  If you really want to get away from a tab maybe think about making them like spoilers that come out of the aileron surface on both sides.

Enough of my two cents.
