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

Combined FET Heatsink and Crystal Mount for Mini-Z AWD

This compact combo accessory is made for Kyosho Mini-Z AWD MR-03 layouts and pairs a fixed crystal mounting point with a heatsink surface aimed at cooling FETs on tight ESC boards. It delivers a tidy electronics area without altering the MR-03 chassis geometry.

Fitment targets MR-03 AWD electronics trays that keep the stock crystal position accessible. The assembly serves as a mechanical support for the crystal while offering a thermal contact area to help reduce FET temperatures during club nights or indoor running.

Installation notes: the bracket lines up with existing screw posts on the MR-03 upper or electronics tray and requires basic disassembly of the radio/ESC area. Confirm antenna routing and ensure the crystal sits without pinching wiring. Use the stock small hex screws or equivalent and check there is no contact with suspension or moving parts before you run the car.

Tuning note: this is a reliability accessory rather than a power upgrade. By fixing the crystal and providing a dedicated heatsink surface near the ESC FETs, it reduces the risk of intermittent radio faults and helps maintain stable ESC behaviour under repeated thermal cycles.
