Your GFs parents bought it???
Wow! Sounds like a keeper! I mean you can ditch the girl but keep her parents!
Anyways, remember not to hurry and repress the need to get it done fast. If you go too fast you will make mistakes. I have a thread titled "4 Star 40 Building Commences". I hope that can help you. At least it can steer you away from some of the mistakes I made!
The kit went together quite well. Just pay attention to the instructions. In fact, read the instruction through entirely before you begin. Also, ensure you have a FLAT, FLAT, and FLAT building board! Also ensure you have a flat building board!
Good luck and if you have any questions, please feel free to drop me a line.
Good Luck!
