Hi, I need some advice. I'm hoping to do some cross country flying once I get this S7 done. Apr 2010s the goal. Is there any reason to add an in flight adustable trim on the wing. I did put rudder trim on but am unsure whether there is any need for trim on the wing. For those that have done long tiips do you feel there would be any benefit. I'm covering the wings now so now's the time to do it. Any advice would be appreciated. Thanks....Ken
