Topdeck Plate for Medius X26 Steel EP SER400052 - Serpent 402187 Hard (2)  [SER402187]

Two hard topdeck plates for Medius X26 tuning work

The Serpent 402187 Topdeck hard ships as an upgrade component for Medius X26 kits referenced by SER400052. The kit contains two "hard" topdeck parts targeted at drivers who adjust chassis flex to refine handling characteristics.

As an upper chassis component, the topdeck adds torsional rigidity to the main plate. Installing a harder topdeck typically reduces twist between front and rear mounting points, which can sharpen steering entry and help stabilise high speed transitions depending on overall setup. Bear in mind that topdeck stiffness changes will interact with suspension and damper settings, so adjust other components as needed.

Installation is straightforward for experienced modellers: remove the body and the existing topdeck fasteners, position the replacement topdeck into the same mounting holes and secure with the original hardware. Check for adequate clearance for radio equipment and battery before final tightening. No special tools are provided.

This Serpent 402187 Topdeck hard (2 pcs) offers a direct method to reduce topdeck flex on Medius X26 cars and should be assessed alongside suspension and roll centre adjustments to achieve the desired handling balance.
