Lower cowl and gear leg fairings

I have been working on the lower cowl and gear leg fairings over the last couple weeks.   Finally got them to a point where I am happy with how things are working/flying.   At first the gear leg fairings affected my trim a bit and the Slip/Skid ball was about ½ off.   I simplify adjusted the gear leg fairings and after two flights of adjustment by trim was dead on.   Not sure why people are so concerned about these, or why they add tabs to their rudder.  A simple minor adjustment on the gear leg fairings straightens things out perfectly.   Anyway, I will probably do some more minor tweaking and fiberglass work/priming then call these done for the summer.
