I copied all the parts onto 13 x A4 sheets, keeping the original dimensions. Some of the larger parts 1 divided into 2 parts, overlapping the joints.
I found a lot of problems with the tab locations. a lot were in the wrong position and clashed with the tabs on the corresponding parts. Also I think it would help if you constructed an internal rib cage as I found that after assembling the main body, it was totally distorted. The artwork itself was very good, it's just that the assembly instructions leave a lot to be desired. You must scrutinise the pictures very carefully to see how the tabs are folded, inside or outside. Also, dry fit the parts as some tabs may need to be trimmed.
I cannot understand why A3 format is used as unless I am mistaken, the majority of modellers only have an A4 printer?
Otherwise, congrats to the designer for an interesting model.
I used MS paint to do the transfers to A4 size.
