Serpent 4X MID Topdeck 2.0mm Chassis Brace - Arrowmax AM-910024  [AM-910024]

Arrowmax topdeck for Serpent 4X Medius MID

This topdeck is an RC-scale replacement designed for the Serpent 4X Medius MID layout and supplied as Arrowmax part AM-910024. It serves as the upper chassis brace that locates the radio tray and shock tower positions while contributing to overall chassis stiffness and on-track tuning feel.

The 2.0mm thickness is chosen to change flex behaviour compared to thinner decks, letting racers tune the balance between front and rear traction by altering chassis stiffness. Focus is on fit and tuning effect rather than cosmetic change. Always confirm the topdeck lines up with your Medius MID mounting points before fitting.

Fitting is straightforward for those comfortable with Serpent 4X assembly: remove the factory topdeck, move required hardware and radio tray parts over, and secure the Arrowmax AM-910024 using the factory screw pattern. If mounting holes do not match, check your chassis revision rather than forcing hardware.

Use this topdeck when chasing a different mid-corner balance through controlled changes in chassis stiffness; adjust shocks and anti-roll settings incrementally while logging results.
