MTX4 Performance Flywheel MTX3-028 by 3Racing  [MTX3-028]

Performance flywheel for MTX4 tuning

This is a lightweight flywheel made for the Mugen Seiki MTX4 platform, identified as MTX3-028. By lowering rotating mass it modifies inertia so the engine responds faster to throttle inputs on nitro cars.

Fitting is performed using standard MTX4 access: remove the body and clutch pack as required, exchange the stock flywheel for this unit, then secure with your original hardware. After installation, recheck clutch timing and torque per the chassis manual to keep engagement predictable.

Tuning takeaway: reduced inertia usually delivers sharper throttle response and faster rev recovery which helps when dialing in clutch springs or throttle curves; approach changes step by step during practice laps.
