My first Modelling Video on Youtube was a review for the Zvezda BT-7. I was enthusiastic with the kit in the box at the start, but as the build went on I realised it had many issues.
So I did a complete photo etch upgrade, aftermarket track links, and a metal barrel. The transformation was sensational and the kit came up very well in the end.
This was the chipping video where I also showed the completed photo etch and other additions.
