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

Replacement flywheel for MRX-5 chassis

The Arrowmax AM-MRX5-H0778 flywheel is an RC replacement machined from 7075-T6 aluminium and designed for use with Mugen MRX-5 chassis configurations. The component emphasises reliable rotational characteristics and stable inertia for setup work rather than promising speculative speed improvements.

Fitment and role: designed to mount in the MRX-5 driveline and to mate with the standard clutch and engine assemblies used on that platform, the flywheel alters spin inertia and throttle reaction; installers remove the factory unit and refit this part in the same location, ensuring correct alignment and secure fastening before track use.

Fit this aluminium flywheel when a dependable replacement is needed to retain steady rotational behaviour for chassis tuning; inspect for fit and balance and re-check throttle mapping after installation.
