At the field I fly at there is a club member who goes over planes before they ever take off on there first flight he also goes over all the controls and gives some basic ground school to new pilots. This member has taught me alot and I probably owe much of my success to him even though he never works on a buddy box. If you are fortunate enough to have a person like this at your field just have him go over everything for you and take the plane up for a trimming flight. Even the planes that start out the prettiest are going to get some wear and tear from normal use. I figure you might as well start out just shy of perfect so you don't embarrass people like me who have a few repairs on our planes.
