I am working on this kit myself. It is a very nice kit and well detailed. My only warnings are be careful with track skirt mounting brackets when you remove them from the sprue, they are quite fragile. Also watch the return wheels, they aren't supported by much and have to be thoroughly dry before you can begin handling the kit. Other than that I didn't find any really noticeable flaws with the kit, but I'm pretty new at this and don't have that great of an eye yet.
