About the MR-04


Advanced MR-04 Chassis for Improved Handling

The MR-04 chassis introduces multiple upgrades over its MR-03 predecessor, including a lower center of gravity and improved steering geometry. These enhancements provide sharper, more predictable handling and better cornering stability, essential for on-road racing. The W-MM (wide, mid-motor) configuration also gives users greater tuning potential, making it easier to optimize performance for different track layouts.

Ready for Customization

Ideal for drivers who want to create a one-of-a-kind Mini-Z, this set is fully compatible with Kyosho’s extensive range of Auto Scale Collection bodies and unpainted white kits. You can paint your body to match a real car or your own racing colors. This level of customization makes it perfect for both casual racers and competitive drivers who demand a personalized RC experience.

Reliable KT-531P Transmitter and Balanced Motor Power

Included in the set is the KT-531P pistol-grip transmitter, a user-friendly and reliable controller that makes the Mini-Z feel like a full-sized race car. The 130-class MZ9PB motor delivers balanced power suitable for both beginners and experienced racers.

Great basic and timeless design
Size: 12 Little Kid, Color: Brown
These sandals are a great find! They’re super easy to get on and off thanks to the Velcro straps, which is a huge win for little ones learning to be more independent. The fit is adjustable and secure, so they stay in place well during all kinds of play. The cork-style footbed is comfortable and gives good support, and the overall design feels sturdy enough to handle everyday wear. They’re lightweight but still durable, and have held up really well so far. They also have a classic, versatile look that goes with just about everything, perfect for summer outfits. Overall, a reliable, comfortable sandal that’s great for active kids. Would definitely buy again!

Great option for boys or girls
Size: 13 Little Kid, Color: Black, Size: 13 Little Kid, Color: Black
This is really more of a unisex option for a sandal. I have sandals that look like this, and both of my children have worn this style. I ordered these for my daughter, with the plan to pass them down to my son if they're not too worn when she outgrows them. The style is very minimalistic, so it goes with lots of outfits. All the straps are easily adjustable, so you can get a good fit. I would say the length is true to size, but the width is maybe a bit wide. Nevertheless, the adjustable straps really help them fit well. They feel really sturdy and I appreciate that the sole has cushion to it. My daughter has worn these every day since I got them out of the closet and they're holding up well.
