Here is a dry fit of the BT-4s with proper length. I also had the idea to use one of the Estes engine spacer tubes as the core tube for the ejection gases to blow up through inside the upper portion of the 1B tanks. The picture with the space tube, engine block and engine stacked should give an idea of what it will look like internally.
