You should absolutely get a tech counselor to look at your project in various stages, they have a nice little sheet that they fill out so it's even more irrefutable you did the work.Since I'm basically the most stubborn person on the planet, I would never do what "steveinindy" is going to do, I really don't want that many drama queens nitpicking my plane. My suggestion is find someone who has built something similar and actually flies it, to look it over, it's a major plus if that guy is an EAA tech counselor. My logs consist of a steno note pad with dated entries and a receipt folder from parts and materials. I have some pictures but not that many, I need a few more with me in them although if the inspector comes out to the farm he'll see where it was built. My bet is unless it looks suspect to him he may never look at them.I'll let you all know hopefully this summer.
