Kyosho Mini-Z AWD Racing FET Heatsink and Crystal Mount AWD-39 by 3Racing  [AWD-39]

Racing Grade FET Heatsink and Crystal Bracket for Mini-Z AWD

Engineered as a compact upgrade for Kyosho Mini-Z AWD MR-03 electronics trays, this combo bracket provides a fixed crystal location and a dedicated heatsink surface designed to improve thermal stability for FETs on small ESC boards. The layout retains original chassis dimensions while delivering a neat electronics footprint favoured in race setups.

Compatibility is intended for MR-03 AWD platforms where the stock crystal position and ESC arrangement permit an add-on bracket. The component acts as a mechanical anchor for the crystal and forms a thermal interface to assist dissipation from FETs during repeated sprint or heat sessions.

Installation guidance: the mount lines up with existing MR-03 upper tray screw points and requires straightforward access to the radio and ESC area. Verify antenna routing and ensure the crystal sits without stressing wiring. Install with the stock small hex screws or direct-fit equivalents and confirm full clearance from suspension and moving parts prior to track use.

Tuning context: this is a reliability and thermal management upgrade rather than a direct power improvement. By providing a stable crystal location and a heatsink contact near the ESC FETs, the bracket helps reduce intermittent control issues and keeps ESC thermal behaviour more consistent across repeated runs.
