Hey all, I have a new project started that involves the recently released MPM 04 Optimus Prime. By now, many of you will know that it is plagued with tolerance and tabbing issues, but I believe there is real potential for improvement. Despite its current issues, which have been demonstrated by a few members to be easily corrected, this is my favorite iteration of movie Optimus. I am in the early planning stages of this project, so some ideas may be dropped, while others may be picked up as I learn the ins and outs of this figure and what is possible to modify. As of now, here is the current list of improvements I'd like to achieve. Improvements: - truck properly tabbed in - second set of wheels for alt mode - split wheels on hip and thigh - wider wheel wells - larger gas tanks - wider headache rack - full doors on chest - accurate Paul drons - accurate backpack configuration - more paint applications The first modification will be the second set of wheels and splitting tire. A few things to note about this. The Peterbilt truck has 2 sets of wheels on the rear, for a total of 8 wheels. In robot mode, this second set seems to disappear, when in reality, the split tires is caused by the first set collapsing into the second. This is a transformation that I would like to include, which will be unique to any movie Optimus figure I've seen so far. Here is the design plan: A prototype made with card stock. I have it placed on as the outside tire, but you can imagine a final product on the inside. Of course, with a second set of tires, you would need a wider wheel well. Fortunately, the Leader class figure has just that. Additionally, the rear wheels on the actual truck stick out further on the sides. They are not flush with the tool box as represented on the MPM. The first order of business is to design and 3d print a working tire. Next would be to remove the original tires, and install the new ones behind, then put the originals back on. A new pin will be required. Lastly, I will need to modify the Leader wheel well to work for the MPM. More to come... Suggestions and advice are welcome!
