Yokomo BD10 Honeycomb Chassis Flex Plate by Arrowmax AM-950025  [AM-950025]

BD10 chassis flex guide

The Arrowmax AM-950025 is an aluminium honeycomb chassis flex plate made for the Yokomo BD10 platform, designed as an aftermarket tuning plate to alter underbody stiffness and affect handling characteristics on 1/10 electric touring cars. The part lines up with BD10 mounting points and gives a consistent mechanical behaviour to include in tuning work.

Presented as a replacement or upgrade option, the plate changes undertray flex through its honeycomb stiffness distribution, which in turn influences weight transfer, corner entry balance and steering feedback when used with standard BD10 suspension and drive parts. Work incrementally on setup and test on a representative surface to evaluate effects.

The item is specified for the Yokomo BD10 and is intended to offer a different baseline for chassis flex tuning compared with stock BD10 plates. It does not imply changes to electronics or the drivetrain, being purely a mechanical tuning part.

Use the Arrowmax AM-950025 as part of a measured setup routine on the Yokomo BD10 to see how different undertray stiffness affects handling balance rather than expecting a single guaranteed improvement.
