Gentlemen, allow me to introduce myself. My name is Gustavo Graziottin. I am an amateur builder and an airline pilot in Brazil. I bought the plans for an SD2 in 2004 and I'm starting construction now. I have no idea how long it will take me to complete the project, even why I will only have my few monthly breaks to dedicate myself. I have already researched and studied a lot. This forum is a wonderful source of information and I am sure I will be able to answer my questions with your help. Thanks in advance. I will try not to repeat questions already asked in the forum. I will start building by the wings. I appreciate any initial suggestions that you can give me.
