A Talented Paper Model Designer at Papermodelers created a model of the TACHI and ROCINANTE. Unless you are a member of the Paper Model Group you won't be able to see the model, however the link for the models and instructions he posted so that anyone can access it. I started building the TACHI and thought I would post my progress with the build here. I don't claim to be an "Expert" model builder, but I do enjoy model building in both plastic and paper. The model is comprised of three modules. I am assembling the DRIVE Module first. The hard part is making the strut support beams that you can see on the bottom of the module. I can only do a few at a time before I need to take a break.
Here are the links for the instructions and the TACHI and ROCINANTE Versions
