MUGEN MTX-5 7075 HARD Flywheel by Arrowmax AM-MTX-T2702  [AM-MTX-T2702]

Flywheel for Mugen MTX-5

This Arrowmax flywheel is an RC-scale replacement part designed for Mugen MTX-5 based chassis, intended to change inertial response between the motor and clutch assembly. The 7075 HARD designation identifies the material category used in the part name and indicates a high-strength aluminum alloy chosen for dimensional stability under load.

Use of an aluminum flywheel affects engine-mimic inertia on nitro or brushed systems in 1/8–1/10 scale RC setups by altering how quickly revs rise and fall during throttle transitions. This unit is presented as a direct spares/hop-up for MTX-series Mugen Seiki models where the part fitment and mounting interface match the original flywheel geometry.

Installation notes: remove the clutch assembly as per your chassis service procedure, replace the factory flywheel with this unit using the original mounting hardware, and verify clearance with the starter or pull-start assembly before final reassembly. After installation, perform incremental throttle tests to confirm expected changes to acceleration and idle stability, and re-check fasteners after initial runs.

As an aluminium replacement flywheel, this part is intended for hobby-grade chassis tuning and routine maintenance where users seek predictable inertial behavior; validate fitment and dynamic effect on a test bench or controlled track session.
