MTX4 Low Inertia Flywheel MTX3-028 by 3Racing  [MTX3-028]

Low inertia flywheel option for MTX4

This flywheel is an RC-specific lightweight unit for the Mugen Seiki MTX4, supplied under part number MTX3-028. Its reduced mass changes the rotational inertia to make nitro engines come on the pipe faster and alter throttle sensitivity.

Installation follows normal MTX4 procedures: remove the body and clutch assembly as needed, swap the original flywheel for MTX3-028, then refit using the existing retaining hardware. Make sure to reset clutch timing and torque settings per your chassis documentation after reassembly.

Tuning guidance: a lighter flywheel is useful for crisp throttle response and faster rev recovery, but it is a setup tool rather than a guaranteed performance upgrade — adjust and test settings incrementally on track.
