Technical Performance
The rear arm shaft is a fundamental component in any RC car's drivetrain architecture, responsible for transmitting rotational power from the transmission directly to the rear wheels. The 3x35mm specification indicates both the shaft diameter (3mm) and length (35mm), dimensions that have been engineered through HoBao's competitive racing experience to provide the optimal balance between strength and weight. The material composition of HoBao shafts is selected to resist bending and twisting under the extreme forces generated during acceleration, cornering and braking in RC racing. This is particularly important in competitive settings where thousandths of a second separate first place from second place, and where component reliability directly impacts race results. The precision manufacturing process ensures concentricity and straightness, preventing vibration and ensuring smooth power delivery to the wheels. For RC car owners in the UK running their vehicles on carpet, asphalt, dirt tracks or grass, the rear arm shaft must be capable of handling the variable terrain and conditions that British RC racing venues present. HoBao's engineering expertise, developed through years of competition at the highest levels of RC motorsport, is evident in every component they produce, including this rear arm shaft.

Frequently Asked Questions
- What is a rear arm shaft and why do I need to replace it? — The rear arm shaft is a critical drivetrain component that connects your RC car's transmission to the rear axle. Over time, shafts can wear out, bend or break due to crashes, jumps or normal wear and tear. A damaged shaft will cause poor handling, loss of power delivery to the wheels, and potentially complete drivetrain failure. Keeping a spare H11259 rear arm shaft on hand means you can get back on the track quickly.
- Is the H11259 compatible with both Hyper Mini ST and Hyper TT models? — Yes, HoBao designed the H11259 rear arm shaft to be compatible with both the Hyper Mini ST and Hyper TT platforms. This cross-compatibility makes it a practical spare part if you own both model types or plan to upgrade between them.
- Where can I buy a genuine HoBao H11259 rear arm shaft in the UK? — RC Model Shop is an authorised HoBao retailer based in the UK and stocks genuine OEM parts including the H11259. Shopping with an authorised retailer guarantees you receive a genuine component backed by the manufacturer's quality assurance, unlike counterfeit or grey-market parts that may not meet specifications.
- How difficult is it to install the H11259 rear arm shaft? — Installation difficulty depends on your mechanical experience with RC cars, but the process typically involves removing the rear wheels, unbolting the rear axle assembly, and replacing the shaft. If you're experienced with RC maintenance, this is a straightforward task. If you're new to RC car repairs, we recommend consulting the official HoBao assembly manual or contacting RC Model Shop for guidance.
- What should I do if my rear arm shaft breaks? — If your rear arm shaft breaks, your RC car will lose power delivery to the rear wheels and become undriveable. Stop immediately and order a replacement H11259 shaft. Keep spare shafts on hand if you race competitively, as a broken shaft during a race will end your event.
