Lightfoot is right. Build your second one. Rebuilding trainers is quite easy. Whenever i crashed mine i took ALL parts home, and then did one thing at a time. They are like a puzzle and fit together that good. As for everything else it looks like good choices. I would prefer O.S. over Evolution. That way, not only can you get everything from one place (tower hobbies is having a big sale right now..) but you will have a good running engine. I don't have any experience with evolutions, but O.S. Makes some good ones from what i've seen.
