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

This 3mm graphite tray is produced as a direct-fit replacement for 1/10-scale Mugen Seiki MRX4 and MRX4-R touring layouts. It offers a flat, rigid platform to secure the receiver and electronics while keeping the internal layout compact for effective cable management and balance adjustments.

Function and fit: the tray installs into the vehicle radio bay and preserves the expected spacing for components on MRX4-series chassis. It helps maintain tidy wiring and provides a neutral reference point when experimenting with electronics placement during setup.

Fitting advice: use the original radio-bay fasteners and factory screw holes when attaching the tray, check that mounts are tight, and add foam isolation or double-sided tape beneath sensitive electronics as preferred. Keep antenna and power leads away from moving linkages.
