Thanks ... I have never built an engine before and this thing has really got my interest and attention, and I want to do it right. First goof --- the pistons are wrong. There are 9. There are only supposed to be 7. Consequently, they are too small in diameter and I am now making new pistons - no big deal, I caught that early. I expect to get my new casting materials today from MicroMark for casting the suspension parts. Building the hull is a piece of cake. The suspension and engine are the frosting to me. Mixing a matching paint color for the hulls and duplicating the Antarctica background to match the photo are going to be the key to this project.
