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

Reduced inertia flywheel for MTX4

This lightweight flywheel is designed for the Mugen Seiki MTX4 platform and carries part number MTX3-028. The unit lowers rotating mass to alter inertia so nitro engines rev more quickly and change throttle feel without modifying the engine itself.

Fitment is straightforward for anyone familiar with MTX4 service procedures: remove the body and clutch assembly as required, replace the stock flywheel with this unit, then reassemble using the original retaining hardware. After fitting, verify clutch timing and torque settings against your chassis manual to maintain reliable engagement.

Tuning note: reducing flywheel mass typically sharpens throttle response and speeds rev-up, which can help when refining throttle curves or clutch springs for different track surfaces. Treat this as a tuning option and test changes progressively during practice runs.
