I spent 5 yrs building my S7 and have been flying it regular for the last 2 yrs. I ordered my kit powder coated. I am seeing increasing corrosion on the horizontal struts, jury struts, and flaperon counter balance weights. I will do my annual soon and do my best to inspect the hard to see areas. My concern is in the areas i cant see, like under fabric ( maybe the fabric protects?), and the wing struts.
Have others had issues?
