The tracks took me at least two hours to build. You need a hand drill in order to clean out the holes or else you will break them when putting them together. I did not use the wire it comes with instead I used staples. I bent the sides of the staples and then cut them to the length I needed them to be. This allows you to not use glue at the end of the tracks. DO NOT PUT THEM IN IF THE DON’T GO IN SMOTHLY, you will break them so observe what the problem is. The box has extra track links and instructions. They are very detailed and gives a more real look. To weather them I used Metal Burnishing Fluid from AK. The price tag is big but it’s worth putting on your best built model.
