The Kyosho MX-01 Mini-Z 4X4 Readyset, complete with 2.4GHz Radio System and Grey 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 (Grey)
Updated review: I bought one of these from AMainHobbies when they first came out and within four days the slipper clutch went out. Trying to return it or get an exchange was a pain because as per AMainHobbies policy and agreement with Kyosho, I had to go through Kyosho first. To make a long story short I got my money back but was disappointed with Kyoshos customer service. AMainHobbies was able to make things right.

I figured I probably got a lemon and gave it a few months to purchase another one. Now I have the 4Runner and the Jeep and haven’t had any issues. They’ve quickly become my go to indoor rigs (and I have them all, SCX24, Enduro24, Orlandoo) The bodies are stunning and these little trucks perform great. I like to compare these to the RC4WD 1/10 crawlers. Beautiful bodies and extremely scale, but not as capable. These are for a scale driving experience, not just rolling over everything in sight.

I wouldn’t recommend these to someone who is into modifying. I think they’re best left stock and perform well out of the box. I highly recommend the Kyosho weighted wheels to offset the body weight. They make a huge difference! I also recommend the light kit. It’s a plug n play light kit and adds to the realism. I love running these little rigs around the house and watching them flex and seeing the brake lights light up.

Overall I’m pleased with my purchase and was satisfied with AMainHobbies for making things right with the lemon I got on the first go around.

Kyosho MX-01 Mini-Z 4X4 Readyset w/4-Runner Body (Grey)
Just received mine today. The throttle didn't work! If your's does the same, unscrew and screw in the motor terminals. That fixed mine. Have really enjoyed running it so far. I have 3 other Mini Z's and a mix of rechargeable AAA's. Runtime on a set of Amazon Basics 900mah batteries is well over an hour (and they are not dead yet). I'm hoping they will release some oil dampers for it. The throttle is smooth and it's very easy to get it to run slow. At this point, I would buy it again.

This little thing is so robust it's still going strong like new after all the daily torments by my 2 yr old. He even sits on top of it while pulling the trigger. Painful to watch but this truck is so strong.

Kyosho MX-01 Mini-Z 4X4 Readyset w/4-Runner Body (Grey)
This is a fantastic little RC. It is a blast to drive inside the house and goes over almost anything (couch cushions, pots and pans, piles of paperwork, kid's toys). All I had to do was drop in AAA batteries and go which was a change for me as I typically buy kit RC cars. The only downside I see performance-wise is it is a little top heavy and tends to roll over easily on inclines. The only issue I had was the screws on the axles housings were tightened too tight by the manufacturer causing the wheels to not run freely. I could tell something was binding up because the car would lean heavily to one side when I drove forward and lean to the other side when I drove backwards. After backing the screws off a bit, it ran much better and rides level. Despite this small issue, I still give it 5 stars given how fun it is to drive and how well it crawls for such a small RC. I hope Kyosho makes more bodies/variations in the Mini-Z 4x4 lineup. I'd love to see an old Land Cruiser body or the new 5th Gen 4Runner.

Third Kyosho Mini-z 4x4 and love them all. By far the most scaled mini rock crawler out there. Great turning radius and control, but wished it had some slightly bigger and more grip on the tires. Longer runtime with the AAA batteries and does add a bit more weight.

I picked one of these up recently and finally got around to driving it. WOW! It is like a true 1/10 scaler, Kyosho really did a nice job on this one. The controller feels nice in hand, and allows for some basic controls. The vehicle itself is extremely responsive to inputs you give via the controller as well as tiny adjustments you can make (like steering trim, etc). The scale looks of this 4x4 are amazing, truly a "10". It handles very well and is designed and built perfectly. Honestly I could recommend anything that I'd change on this. Just waiting for the light kit to come in stock as well as any option parts from Kyosho (scale parts to add to the vehicle would be cool as would a small carrying case so I can "throw" it in the back of my car).

First off, the body on this truck has the better detail than you would see in larger trucks. The small size is great for crawling round the house. Great little truck!

BEAUTIFUL, turning radius is out standing. Crawls ok, they absolutely need slightly larger gripper tires and soon, it will definitely make it more capable.

After waiting over a month for this backordered item to show up, it arrives with no battery trays. The model is useless without them. I contact Amain to resolve the issue and I was straight lied to saying they don't carry parts for this item. I've always liked shopping at Amain, been a customer for years, until receiving this kind of unacceptable customer service. Needless to say this will be my last purchase here.
