I can build ARFS and ARCS, but not kits. noone builds for me. I do everythin myself. I tell ya man, college scares me cause I know that i will have to not fly a lot to get through it. We'll see what I have to sell when the time comes. Id love to see videos, have any of the Katana?? I like the Katana, but if i ever get one it would be a 35 or 40%.
