Arrowmax AM-910003 Medius MID Conversion Kit for Yokomo BD9  [AM-910003]

Mid-Motor Conversion Built for Yokomo BD9 Drivers

Built for Yokomo BD9 owners who want sharper handling, the Arrowmax AM-910003 AM Medius MID Conversion Kit converts the layout to a mid-motor configuration to increase steering response, traction, and cornering pace. Moving the motor toward the centre improves agility and makes high speed control more predictable.

Chassis Options for Racing and Practice

The kit supplies two chassis styles to match different track demands. You can run a 2.25mm carbon fibre chassis for a light, stiff feel or a 2.0mm alloy chassis where extra toughness is preferred. Both choices come with a 2.0mm carbon fibre upper deck to maintain chassis strength and balance.

Precision Parts Focused on Drive Efficiency

This package includes a precision 7075 alloy single-piece motor mount that secures the motor while reducing vibration. Redesigned 7075 centre pulleys improve power transfer for cleaner acceleration and higher top speed. A chassis stiffener is also included so you can tune flex to suit track grip and handling preferences.

The Arrowmax AM-910003 conversion kit is aimed at Yokomo BD9 racers who want to refine handling and speed with verified hardware and flexible setup choices. It is well suited to drivers who adjust chassis behaviour to find the best lap time.
