HPI Savage / Savage X / Savage K4.6 Engine Alloy Fly Wheel by GPM SAV1100E  [SAV1100E]

Engine flywheel for HPI Savage

This aftermarket alloy flywheel is made for RC-scale HPI Savage platforms and is offered as a direct-replacement component for Savage, Savage X and Savage K4.6 engines. The item is an alloy flywheel with three posts, designed to match the mounting pattern specified in the product name.

Functionally, a flywheel alters rotational inertia which affects engine idle stability and throttle response on nitro-powered RC engines. Using a heavier or lighter flywheel changes how quickly the engine revs and how it returns to idle; this alloy unit provides a durable alternative to stock parts while keeping the intended mounting layout.

Installation is a straightforward engine-level swap: remove the existing flywheel, align the three-post pattern with the engine crank, and secure according to the engine manufacturer's torque practice. This part is an RC accessory for HPI Savage models and should be handled as a model engine component during fitting and adjustment.
