31mm diameter Centax-3 flywheel.
Serpent has introduced this new, smaller diameter, Centax 3 flywheel for use on your Serpent 720. Now 31mm in diameter, this flywheel is 2mm smaller than the original version and this allows you to use both the LCG engine mount (#803209) and the LCG chassis (#803199) without risking the wheel hitting the track surface. Apart from the diameter changes the flywheel is still the same lightweight, high quality, item that is included as standard in the kit.
