BD9 MID Upper Deck for On-Track Tuning

The Arrowmax AM-910020 topdeck is an RC replacement part intended for the Yokomo BD9 MID chassis, supplied at a 2.0mm thickness. It serves as the upper chassis plate joining the front and rear bulkheads and contributes to the vehicle's torsional rigidity.

Built for tunability, changing topdeck thickness alters mid-corner balance and the car's transient reaction without touching suspension geometry. Use this deck as a direct swap in BD9 MID configurations to preserve factory mounting points and alignment.

Fitting is simple on typical BD9 MID builds—remove the existing topdeck, align the mounting holes and tighten screws evenly to avoid twisting. During setup, run controlled tests after each change and log observations to separate the deck's influence from other setup factors.

Specifications

  • Item: Topdeck
  • Material: Not specified
  • Model Number: AM-910020
  • Compatibility: Yokomo BD9 MID

As an optional upgrade for the Yokomo BD9 MID platform, this topdeck is intended for model racers who prefer measured tuning; use it to test chassis stiffness changes methodically during setup sessions.

Will this affect steering precision?

Increasing deck stiffness can sharpen steering response and reduce flex-induced vagueness, but final precision depends on the whole setup including servo tuning and tie-rod geometry.

Is mounting hardware included with the deck?

Inclusion of screws or spacers varies by retailer; assume hardware is not included unless the listing explicitly states otherwise and check before purchase.

Can I use this with reinforced or aluminium bulkheads?

You can, but confirm stack heights and hole alignment when mixing aftermarket bulkheads and decks; different bulkheads can change chassis behaviour and mounting clearance.

Any final installation pointers?

Use progressive, even torque on fasteners, double-check for electronic interference under the deck, and recheck alignment after initial test runs.
