Overview
The BLH Aluminum Tail Drive Shaft Lower Bearing Block (Z-BLH1654A) is an essential replacement and upgrade component for Blade RC helicopters, specifically designed to fit the Blade 450 and Blade 400 models. This precision-engineered bearing block forms a critical part of the tail drive system, providing stable support for the tail shaft assembly and ensuring smooth, reliable operation during flight. Whether you're repairing after a crash, replacing worn components, or upgrading your RC helicopter for enhanced performance, this genuine Blade spare part delivers the quality and durability you need to keep your model in top flying condition.
For RC helicopter enthusiasts across the UK, maintaining the integrity of the tail drive system is absolutely crucial for safe and predictable flight characteristics. The tail drive mechanism is responsible for transmitting power to the tail rotor, which controls the helicopter's yaw movement and overall stability. A worn or damaged bearing block can lead to excessive play, vibration, and unpredictable handling, making this component a critical part of routine maintenance and repair work. This aluminium bearing block is manufactured to Blade's exacting specifications, ensuring perfect compatibility and reliable performance with your Blade 450 or Blade 400 RC helicopter.
RC Model Shop specialises in genuine Blade spares and upgrades, stocking a comprehensive range of components to keep your RC helicopter fleet in pristine working order. Whether you're a seasoned RC helicopter pilot, an experienced RC hobbyist, or someone looking to upgrade and maintain their Blade model, we've carefully selected this bearing block because it represents genuine Blade engineering and proven reliability.

Technical Performance
The BLH Aluminum Tail Drive Shaft Lower Bearing Block represents precision engineering in RC helicopter component design. The aluminium construction provides excellent stiffness-to-weight characteristics, ensuring the bearing block maintains proper shaft alignment without adding unnecessary mass to the tail drive system. The lower bearing block position is critical to the overall tail rotor drive assembly, as it supports the lower end of the tail shaft and works in conjunction with upper bearing blocks to maintain concentricity and minimize radial runout. Proper bearing block alignment is essential for smooth power transmission from the main gearbox through the tail drive belt system to the tail rotor assembly. This component integrates with the Blade 450 and Blade 400 tail drive systems, which typically employ belt drive mechanisms for their efficiency and smooth operation. The bearing block must support significant rotational forces whilst maintaining precise alignment tolerances, and the aluminium material offers the ideal combination of structural integrity and weight efficiency for this demanding application. When installing or replacing this bearing block, proper alignment with mating components ensures optimal tail rotor response and eliminates the vibration and control lag that can result from worn or misaligned bearing surfaces. This is a component that sees regular operational stress and wear, making periodic inspection and replacement part of responsible RC helicopter maintenance practices.
