Hi everyone. I am attempting to build the white version of the external tank due to part availability in New Zealand, but an really struggling with the internal pieces required to complete the section beneath the cone section. I have all the external pieces but cannot seem to master the attachment angles for the angled sections around the circumference. If anyone could give me a h int (or even an internal picture) as to how it can be achieved, I would be very grateful. Kindest regards. Richard.
