Mid-Motor Conversion for Yokomo BD9 - JR-BD9CK by Jazrider  [JR-BD9CK]

Overview of the BD9 Mid-Motor Option

This conversion kit enables the Yokomo BD9 touring car chassis to accept a centrally mounted motor, moving it from the stock rear location into the chassis center to explore different handling characteristics on track.

The supplied parts focus on the interface between motor and drivetrain, offering mounting and alignment features that place the motor correctly in relation to the gearbox and spur gear. The kit is intended for scale RC models only and not for full-size vehicles.

Installation requires removal of the original motor mount and installation of the conversion components on the BD9 chassis. Check motor height, spur engagement, driveline alignment, and clearances for the ESC and receiver during fit-up. The kit is suited to hobbyists experienced in chassis teardown and drivetrain setup.

The JR-BD9CK provides a straightforward way for BD9 owners to trial a mid-motor configuration and assess its effect on balance and on-track behavior without replacing the whole chassis.
