kyosho didnt make xmods. the miniz has sub hobby grade electronics in it, IE a high resolution servo and speedo. also mini-z are popular depended on where you live. out here lots of people know about or have mini-z. there are races all the time. and mini-z have hundreds of hop-ups. you would not believe! radio shacks selection thus far is limited in comparison. and mini-z bodies have a little more detail than xmods do, well the autoscale collection does anyways. and miniz are faster
just to let you know there is no bias here, i hate my miniz, i just have it cause it is pretty
