Great addition to a great model. Some of the wiring remains a bit too visible and takes some extra effort to hide, but in general it enhances the model greatly. As with most other kits the instructions using photographs are hard to read, especially with this model, with black wires on a lot of black bricks! It would really help if the instructions were available online, so the images could be enlarged
