This CNC-friendly alloy heat sink holder is engineered for Kyosho Mini-Z AWD platforms, including MR-03 AWD chassis. It supports compact motor heat sinks and provides a firm mounting interface to assist passive thermal dissipation during extended runs and bench tuning.
Installation notes: remove the body shell to expose the motor bay, then locate the holder on the MR-03 AWD motor mount points. Verify motor axial and radial clearance before final torqueing to maintain correct gear mesh and prevent contact with adjacent components. Install using existing chassis screw positions and confirm with the product listing whether fasteners are included.
Tuning role: the holder secures motor placement and optimises heat sink contact and exposure to airflow, aiding thermal stability under continuous or high-load operation and supporting repeatable setup checks.
