Precision Radio Tray for Competitive MRX4 Setups

The 3Racing MRX4-17/SG 3mm graphite radio tray provides a stiffer mounting platform for the Mugen Seiki MRX4 and MRX4-R chassis, improving consistency in handling characteristics across laps. Its flat, accurately machined profile supports reliable radio and battery positioning for precise setup adjustments.

Material Choice and Performance Impact

Graphite offers a high modulus to weight ratio, which is useful when tuning for minimal flex without increasing mass. The 3mm thickness was selected to balance rigidity gains with practical durability for race use.

Fitment and Installation Notes

Engineered to align with MRX4 and MRX4-R factory mounting points, the MRX4-17/SG reduces fitment variances and simplifies installation. Verify screw lengths and clearance on bespoke electronics stacks to maintain secure, vibration free mounting.

Specifications

  • Material: Graphite
  • Thickness: 3mm
  • Compatibility: Mugen Seiki MRX4, MRX4-R

How does tray stiffness influence setup tuning?

Increased tray stiffness reduces chassis twist, which can shift tuning emphasis toward shock and antiroll bar settings to regain desired weight transfer and front end bite.

Are there recommended mounting practices to avoid stress risers?

Use correct length fasteners, avoid over tightening, and inspect mounting holes for burrs. Consider small nylon washers to distribute load if using aluminium hardware.

What should I monitor after first installation?

After initial runs check for any chassis rubbing, verify radio gear security, and log handling changes to determine if shock or roll bar adjustments are needed.
