The Kyosho MX-01 Mini-Z 4X4 Readyset, complete with 2.4GHz Radio System and Red Toyota 4Runner Body, is a totally different addition to the popular MINI-Z series that is built with the attention to scale detail and quality design expected of Kyosho. Introducing the "MINI-Z 4x4", a design that allows MINI-Z fans to expand their horizons with climbing and crawling capabilities. This scale 4x4 beauty features a fine-tuned overall design, superior driving performance and high-quality injection-molded scale body construction. 

One of the main draws of the MINI-Zs has always been the greater emphasis of body detail and quality of finish, and the 4x4 surpasses existing benchmarks set by the MINI-Z series. The body is molded with thicker material to better resist crash damage from operation in rough terrain. Incorporating the same ladder- style frame of real 4WD vehicles, the MINI-Z 4x4 boasts a 3-link rigid axle suspension combining what would normally be two upper links into a single upper A-arm to deliver maximum suspension movement. A specially designed high-torque steering servo enables this machine to throw its elbows around in the hard terrain for excellent performance in the toughest rock-crawler conditions. The high-torque 130-size motor brings out the beast in the MINI-Z 4x4, specially geared to run well in the low to medium speed ranges common in crawling.

Designed to balance exquisite style, scale detail and superior driving performance, all the MINI-Z 4x4 needs is eight AAA alkaline batteries (sold separately). Whether you take your MINI-Z 4x4 to your local park or just crawl across your own desktop, the Mini-Z 4x4 is a mini crawler that delivers a full range of scale crawling performance in a smaller, compact package.

Kyosho MX-01 Mini-Z 4X4 Readyset w/4-Runner Body (Red)
I must have got a lemon. I returned this and Amain was great about it. I really wanted to love this truck and I know some people are crazy about these. Mine showed up dysfunctional. I had to do some driveshaft maintenance to get it up and running. I also bought the LED light kit which wasn't as easy to install as I thought it would be. As you can probably tell from the description these use AAA batteries, not a Lipo pack. I was thinking this would be better but I found them overly tricky to put in and install the plastic holder. I don't even have big hands and had a hard time weaseling my way around this thing. So I got the driveshaft fixed, light kit in the body, and battery installed, and then found out the transmitter/remote doesn't work. Quadruple checked everything and nope, something is not working in the transmitter. Like I said Amain was great about this, I sent it back although I had to pay like $14 to ship the stupid thing. On a positive note, the body is sick looking. It's by far the most scale looking body I've seen for the micro-scale and looks sweet with lights. In hindsight, if you have small hands and are fairly experienced with RC this might be a fun one to have in your collection. I personally would just buy an Axial SCX24. I have two of those and an RC4WD D90 and the Axial isn't quite as "scale" but its functionality is through the roof better and easier. Just my 200 cents, keep in mind I'm just an opinionated idiot.

This is my third Mini-Z and my favorite by far. It is very much like a 10th scale crawler just scaled down. The sports light kit works perfectly FYI and takes it to the next level of realism. It is much smaller than the closest competitor, the Axial SCX24, but the fit and finish are the usual Kyosho perfection. The suspension is a little bouncy but that's almost impossible to dampen given the size and weight considerations.
