Thank you for the kind words. For the most part, the model is very straight forward (if you pay attention to the instructions). Granted, there are a few slightly tricky areas, but like I said, if you pay attention to the instructions, you should not have any real problems. I am not certain of the final weight of the model, but i can tell you that the weight of the paper itself is 250 g/m2 cardstock (this is what I have right at this time). Although, the creator of the original model (Martin Saenger) suggest to use 160 g/m2. So when can we see your build thread?
