MUGEN MRX-5 Precision Flywheel 7075-T6 AM-MRX5-H0778  [AM-MRX5-H0778]

MRX-5 flywheel details

The Arrowmax AM-MRX5-H0778 flywheel is an RC-scale replacement component machined from 7075-T6 aluminium, intended for Mugen MRX-5 chassis configurations. The design targets steady rotational behaviour and usable inertia characteristics rather than claiming broad performance gains, making it suitable when a stock unit limits tuning options.

Fitment and role: engineered to locate in the MRX-5 driveline and to pair with standard clutch and engine assemblies used on that platform, the flywheel changes spin inertia and throttle response; installers remove the factory unit and refit this part in the same position, confirming alignment and secure fastening before use.

Use this flywheel when a rugged aluminium replacement with consistent rotational traits is required for setup work; inspect mating surfaces and check balance during installation and re-evaluate throttle behaviour after fitting.
