XRAY T4 MID Topdeck 2.0mm Hard Type 2 by Arrowmax AM-910015  [AM-910015]

T4 MID topdeck overview

This Arrowmax AM-910015 topdeck is an RC-scale hop-up designed for the XRAY T4 mid-motor layout, supplied as the 2.0mm Hard Type 2 variant. It serves as a structural upper plate that links front and rear suspension mounts, and its 2.0mm hard specification reduces chassis flex relative to softer topdecks, helping to stabilise handling when tuning roll and steering response.

Compatibility is focused on the XRAY T4 series with MID configuration; the part is intended for model-level adjustment rather than any full-size application. Installation requires removal of the stock topdeck and transfer of existing hardware to maintain original geometry. Because this is a scale racing component, confirm fitment against your T4 variant before final assembly.

Choose this topdeck when you need a firmer upper plate to reduce chassis flex on XRAY T4 MID setups; it acts as a tuning step between softer and stiffer options and is best evaluated on-track for balance changes.
