Technical Performance
The Losi Transmission, Pinion assembly represents precision drivetrain engineering optimised for the 1/24 and 1/28 scale micro RC platforms. The transmission housing and internal components are engineered to handle the torque output from small brushed or brushless motors whilst maintaining smooth power delivery to the drive wheels. The fully built construction means all gearing has been carefully assembled with proper bearing placement and mesh alignment, critical factors that directly affect efficiency and responsiveness. The pinion gear ratio is specifically matched to work with the Micro-B and Micro-T's internal transmission gearing, providing the correct overall gear reduction for optimal acceleration and top speed balance. The motor screws included are grade-matched fasteners that secure the motor to the transmission assembly without over-tightening, which could cause binding, or under-tightening, which would result in slippage. For micro-scale RC cars, where tight tolerances and precision engineering are paramount, this genuine Losi assembly ensures your drivetrain performs as intended, delivering consistent torque delivery and extending the service life of your motor and gears through proper load distribution.
