Serpent 4X Chassis Arrowspace Mg Extra Flex by Arrowmax AM-900008  [AM-900008]

Arrowspace Mg extra-flex plate for Serpent 4X

This Arrowmax AM-900008 Arrowspace Mg Extra Flex plate is an RC-scale chassis hop-up designed to alter flex characteristics on Serpent 4X platforms. It is a dedicated upgrade part intended for hobby use on compatible Project 4X variants, offering an alternative stiffness profile for chassis tuning without changing primary suspension or drivetrain parts.

Fitment and role: the component is positioned as a chassis plate/brace replacement to adjust the chassis flex envelope. Changing to a magnesium extra-flex plate helps tune mid-corner compliance and steering feedback by shifting how the chassis distributes load between suspension components. This part is intended for controlled tuning setups where riders test incremental changes to handling.

Installation notes: installation requires basic disassembly of the chassis center section and reusing existing mounting hardware; standard hand tools used for Project 4X maintenance are sufficient. Verify alignment and thread engagement during reassembly and check that clearances to the motor, ESC, and servo are preserved. No modifications to external drive components are required.

Tuning guidance: use this plate as one variable in a wider setup process. Combine with suspension and tire adjustments, and log changes one at a time. Expect subtle handling shifts rather than dramatic changes, suitable for on-track trimming and balance adjustments at the RC scale.
