Mugen Seiki MRX4/MRX4-R Precision 3mm Graphite Radio Tray MRX4-17/SG by 3Racing  [MRX4-17/SG]

This 3mm graphite radio tray is an exact-fit replacement for 1/10-scale Mugen Seiki MRX4 and MRX4-R electric touring chassis. It creates a rigid mounting surface for the receiver and small electronics while preserving a compact internal layout for tidy wiring and stable balance characteristics.

Intended use: the tray locates in the radio bay to retain the original component spacing used on MRX4-series cars. It helps keep cabling neat and provides a consistent baseline for trying different electronics positions during setup without changing suspension or drivetrain geometry.

Fitment advice: secure the tray with the vehicle's existing radio-bay screws and factory holes, check all fastenings are firm, and use foam or adhesive pads to isolate the receiver from vibration if needed. Route antenna and power leads to avoid contact with moving parts and to preserve steering and suspension movement.
