Mini-Z AWD FET Heatsink and Crystal Mount for Kyosho MR-03 AWD-39 by 3Racing  [AWD-39]

Integrated Crystal Mount and FET Heatsink for Mini-Z AWD

This integrated option is intended for Kyosho Mini-Z AWD MR-03 cars, offering a secure place to locate the crystal and a low-profile heatsink surface to assist cooling of FETs on small ESC boards. It keeps the electronics bay neat while leaving chassis geometry unchanged.

Compatibility centres on MR-03 AWD electronics trays where the stock crystal mounting point is accessible. The component combines mechanical support for the crystal with a thermal interface to move heat away from FETs during typical indoor or short-track running.

Fitting notes: it aligns with the MR-03 upper or electronics tray screw points and requires basic removal of the radio/ESC section. Double-check antenna routing and confirm the crystal does not pinch any wiring. Fit with stock or equivalent small hex screws and ensure no contact with suspension parts before testing.

Practical effect: this is a service and reliability item rather than a performance enhancer. By locking the crystal in place and adding a heatsink surface near the FETs, it helps reduce radio interruptions and keeps ESC behaviour consistent through repeat runs.
