Dan awsome build ...you get 5 star from me too...Looking like you are gona get a few spare parts ...Maybe convince you to jump to 1/14 scale lol...You have some great ideas as well and thinking outside the box to make things work ...I envy you for tackleing such a small scale...The machine Greg was thinking about is this one ...this is a large scale non working model at a local machine shop on the island.
