Mugen Seiki MTX4 Light Weight Fly Wheel by 3Racing MTX3-028  [MTX3-028]

Light weight flywheel for MTX4

This is an RC-scale light weight flywheel intended for the Mugen Seiki MTX4 platform, supplied by 3Racing as part number MTX3-028. The part is described as "light weight", and its role is to change rotating inertia to influence engine response and throttle feel on nitro-powered model cars.

Installation is straightforward for hobbyists familiar with spur gear and flywheel access: remove the body and clutch assembly as required on the MTX4 chassis, swap the original flywheel for this unit, and reassemble using the existing retaining hardware. Use the correct clutch timing and torque settings recommended by your chassis manual when reassembling.

Tuning role: a lighter flywheel reduces rotational inertia, which typically sharpens throttle response and makes engine rev-up quicker, useful when adjusting throttle mapping or clutch engagement for track conditions. It is a tuning component rather than a performance guarantee, and changes should be tested incrementally during practice runs.
