I'm building an early 320 Fastbuild - small tail.
 
Questions about the Elevator and Horizontal Stab.
 
1 - Plan to use an elevator trim tab and small RAC servo.  What dimensions should I make the trim tab?  I know there are easier ways, but I am intrigued by the TruTrack auto pitch trim.
 
2 -  Should the elevator trailing edge have a flat surface - similar to the ailerons?  1/4 inch like the ailerons?
 
3 - Plans call for the counter balance ends to be 2 inches wide.  Is this correct and adequate?  Seems that they could be made 1/4 to 1/2 inch wider.
 
4 - My construction manual states the correct horizontal stabilizer incidence is  -1/2 to -1.0 degree.  Is this still the proper range?  If I could build with 100% accuracy, which would be best -1/2 or -1.0?
 
I did search the archives but did not come to any conclusions - thus the questions.
 
Looking forward to feedback and suggestions.
