Here's a guide to see if you need any side thrust.

Fly model away from you INTO any wind; Pull to straight vertical at normal cruise speed. DO NOT use rudder

A. Model continues straight up = No Adjustment
B. Model yaws left AFTER line established = Add right thrust
C. Model yaws right AFTER line established = Reduce Right thrust

Again, 2 degrees is normal for your typical low-wing sport model. Your milage may vary...
