Each have their own advantages. ZipZaps are a LITTLE more upgradeable than MicroSizers (I.E. hubcaps, different tire treads, same wheel sizes) and they have the sweetest bodies you can find for any micro RCs. BUT microsizers have better mods like the dual cell and the stock battery has more power output than a Zip, but about half the runtime capacity. AND, MicroSizers have smaller front wheels that a ZipZap, but SLIGHTLY larger back wheels. The ZipZaps and MicroSizers have the same gear ratios, but different motor rpms. See, for ZipZaps, the motors you can get in the stores are 16,000 rpm, 21,500 rpm, 23,500 rpm, 28000 rpm, and 34,000 rpm. But for MS there is only 10,000 rpm, 16,000 rpm, 22,000 rpm, and 26,000 rpm, but that's only in physical stores. Online is a WHOLE different story. And MicroSizers and ZipZap motors are compatible, just require some adjusting. There is a certain type of MS that has a turbo button, the MS pro. When not pressed, an MS is slower than normal. But when pressed, it goes to normal speed. So if you can amp up the non-turbo speed to normal, then you will have a better MS.

For more speed in physical stores and more runtime, try the ZipZaps. For a turbo button or normal speed in stores, but higher speed than ZipZaps from online stores, get the Micro Sizer/Pro.

edit: in america, it's called a microsizer, but in japan it's bit char-g. In europe it's LXX char-g.
