Mini-Z RWD MR-04 Chassis Transmitter Set

The Hobby Hideaway Verdict: The Ultimate Blank Canvas for AAA Class Dominance! For racers who already know exactly which aerodynamic shell and tire compound they want to run, this chassis and transmitter set is the perfect starting point. The staff at Hobby Hideaway loves this package because it delivers the revolutionary, next-generation performance of the MR-04 platform without forcing you to pay for a factory-finished display body you might not use on the track. It is a pure, unadulterated racing chassis ready for your custom setup and tuning.

Revolutionary Front Suspension & Complete Customization The magic of the MR-04 lies in its ground-up redesign. Kyosho completely re-engineered the front suspension, integrating the kingpin and steering knuckles to drastically lower the chassis's overall center of gravity. This translates to incredibly flat, stable cornering without the dreaded traction rolls on high-grip indoor surfaces. Furthermore, the newly upgraded steering potentiometer and revised gear ratios provide a steering feel that is lightning-fast and unbelievably precise. Because this set comes as a bare rolling chassis, you have the absolute freedom to mount a high-downforce Lexan shell or a perfectly offset wheel set right out of the box.

Key Features & Technical Specs:

• Next-Gen MR-04 Chassis: The latest evolution of Kyosho's rear-wheel-drive platform, featuring a completely redesigned, ultra-low front suspension system.

• Builder's Choice Platform: Arrives as a bare chassis without a body, wheels, or tires, allowing you to custom-build your ultimate track weapon from the ground up.

• Enhanced Steering Precision: Upgraded steering potentiometer and optimized gear ratios deliver razor-sharp, linear steering response.

• Lower Center of Gravity: The chassis layout mounts the AAA batteries even lower than the previous generation, locking the car to the track through high-speed sweepers.

• Included Transmitter: Comes paired with the reliable Kyosho Syncro KT-531P 2.4GHz transmitter for glitch-free control.

• Ball Bearings Included: Equipped with a full set of precision ball bearings for maximum drivetrain efficiency and longer run times.

Hobby Hideaway Pro Tip: When building out your bare MR-04 chassis, paying attention to the motor mount configuration and wheelbase is critical! The chassis can be adjusted to fit various wheelbases (such as 90mm, 94mm, or 98mm), but you must ensure your chosen motor mount (RM, MM, MM2, or LM) fits the specific body shell you plan to run. If you are aiming for AAA Class domination on the indoor track, setting up for a 98mm wheelbase with an MM2 motor mount is generally the sweet spot for a perfect balance of steering and rear grip!
