This alloy flywheel is produced for compatibility with HPI Savage Nitro off-road series and is supplied as model JR-CHP-SAV-007. The unit pairs a turned aluminium flywheel with a set of three-block clutch shoes to serve as a replacement for standard Savage nitro flywheel assemblies.
Installation follows the usual sequence for nitro engine flywheels: remove the flywheel nut, slide off the original assembly, retain and transfer any spacers or keys, fit the new flywheel and tighten to the engine maker's torque. The description assumes conventional Savage drivetrain interfaces.
In practice, the flywheel affects engagement characteristics through its inertia and the shoe geometry; periodic inspection of shoe wear and flywheel runout will help keep engagement consistent for trail or track use.
A practical, direct-replacement flywheel for Savage nitro chassis where aluminium construction and a three-block shoe configuration are desired for predictable drivetrain response and routine tuning work.
