Serpent 4X MID Medius Upper Deck 2.0mm - Arrowmax AM-910024  [AM-910024]

Medius 4X MID upper deck by Arrowmax

This replacement topdeck is made for the Serpent 4X Medius MID chassis and sold as Arrowmax AM-910024. It functions as the upper brace that secures radio tray and shock tower alignments while contributing to chassis stiffness and tuning feedback.

Engineered for setup changes rather than looks, the 2.0mm plate alters flex characteristics versus thinner options, helping drivers refine front-to-rear traction tradeoffs through controlled stiffness changes. Always verify the deck lines up with your Medius MID mounting points prior to fitting.

Installation follows typical Serpent 4X procedures: remove the original topdeck, transfer any necessary hardware and the radio tray, then fasten the Arrowmax AM-910024 to the standard mounting locations. If holes do not match exactly, confirm chassis and part revisions before forcing screws.

Fit this topdeck when testing chassis stiffness changes to influence mid-corner grip; pair with gradual shock adjustments and note handling changes lap by lap.
