So I got Roadbuster in the mail on Saturday, and *finally* figured out how to transform him correctly after two days. Now, I followed the instructions, and grant it, Roadbuster has a lot of fiddly bits, and there is a lot to cover in the instructions, but after really examining the toy and analyzing Roadbuster's instructions, it seems that Hasbro has completely left out major steps regarding how to fix his chest. Now before I explain this, if you are happy transforming RB based on the instructions that's cool; but I would recommend trying this just once to see if you like it. If you push the front end of the car forward you can actually peg in his chest around the engine block by using the same holes that the machine gun fit over when changing to vehicle mode(first pic). If you do this the shoulders line up better so you can actually tab in the arms at the shoulders (second pic). Doing this eliminates all of the gaps around his head, and makes him a much more solid figure, and helps hide his skinny waist (third pic).
