RE: Truggy vs Buggy?
both the x ray and mugen are pretty much on par in terms of performance and durability, but the mugens instructions are very vague so it can be a pain to build, and the mugen is about 200 grams (half a pound) heavier then the x ray, and the mugen costs more even if only by a few dollars, i'd go with the x ray, they are leading the truggy, and buggy scene in my opinion.
