Joe - It's going to be great watching you build the D-9. Concerning the landing gear, did you check out that link I sent John (I think it was John) about the issues with the landing gear on the Tamiya, DML and Tri Master kit.
Greg - That is the absolute joy of building with the folks here. The amount one learns here is amazing. This leads me to point out to you that our modeling addiction can have certain side effects. I, for one, suffer from the inability to stop buying reference books. I LOVE reference books. I have at least 5 or more books on each kit/subject I have in my stash. Given that I have 70+ kits that means I have, well, you can do the math. This not counting just the general subject and history I have. So, fair warning that you may need to account also for the space required to accomodate one's book stash. That reminds me, I have to share later my latest addition on FW 190s.
