TRX10328

Overview

The Traxxas Propeller shaft/flex cable/stuffing tube (TRX10328) is an essential replacement component designed specifically for the Traxxas Spartan SR high-speed racing boat. This precision-engineered drivetrain part is crucial for maintaining optimal performance and reliability in your RC boat during intensive use on water. Whether you're a competitive RC boat racer looking for spare components or a dedicated enthusiast who wants to keep their Spartan SR in peak condition, this replacement assembly ensures your boat continues to deliver the extreme performance Traxxas is renowned for.

As a dedicated RC hobbyist in the UK, you understand that regular maintenance and timely replacement of wear items are essential to keep your RC boat running smoothly season after season. The propeller shaft and flex cable assembly is one of the most critical components in your Spartan SR's drivetrain, as it transfers power from the motor directly to the propeller. Over time, through regular operation on water, this component experiences significant stress and wear, which can affect your boat's acceleration, top speed, and overall handling characteristics.

This genuine Traxxas part is engineered to exacting standards using quality materials that withstand the demands of high-speed water racing. By choosing an authentic Traxxas replacement component, you're investing in reliability and performance that matches your boat's original factory specification. The TRX10328 is the perfect choice for RC boat enthusiasts who demand nothing less than genuine Traxxas quality and compatibility.

Technical Performance

The propeller shaft and flex cable assembly represents the core of your Spartan SR's drivetrain, responsible for converting motor torque into propeller rotation with minimal loss and maximum efficiency. This component must endure extreme stresses during high-speed operation, rapid acceleration, and sustained runs in challenging water conditions. The flex cable design allows for smooth power delivery whilst accommodating the natural flexing and movement of the boat's drive strut during cornering and dynamic manoeuvres. The stuffing tube provides a sealed interface between the inside of the hull and the external water environment, preventing water ingress whilst allowing the drive shaft to rotate freely. Traxxas engineers have optimised this assembly for the Spartan SR's surface-piercing propeller configuration, which is the foundation of the boat's legendary high-speed performance and handling characteristics. The PTFE (polytetrafluoroethylene) washer mentioned in Traxxas maintenance documentation (part number 1985) is an important component of this assembly, providing low-friction sealing at critical contact points. When properly maintained with regular lubrication using genuine Traxxas marine grease—applied every three runs or approximately every 15 minutes of full-throttle operation—this assembly will deliver consistent performance and maximum drivetrain life for your RC boat.

Maintenance and Care

Proper maintenance of your propeller shaft and flex cable assembly is critical to maximising component lifespan and maintaining peak boat performance. After each run on the water, you should remove, dry, and lubricate the drive cable with Traxxas marine grease—use only genuine Traxxas marine grease, as light oils are insufficient for this waterlogged environment. The flex cable should be regreased every three runs or approximately every 15 minutes of full-throttle operation. To remove the cable for maintenance, loosen the collet that secures it to the motor using a 10mm wrench—you need only loosen it by a single turn, not remove it entirely. Pull the propeller straight out to extract the cable from the stuffing tube. Always inspect the 5x8x0.5mm PTFE washer on the flex cable; if it's missing or damaged, replace it immediately using part number 1985 to maintain proper sealing and performance. Before reinstalling the cable, apply a liberal coat of genuine Traxxas marine grease to the entire length of the cable, then reverse the removal steps to reinstall it. Wipe away any excess grease that squeezes out at the drive strut. Additionally, lubricate the motor bearings with light oil after each run and dry and lubricate the bushings in the drive strut to ensure the entire drivetrain operates smoothly and efficiently. Check all screws in the drive system regularly for tightness, as vibration and water exposure can loosen fasteners over time.

Frequently Asked Questions

• What maintenance does the Traxxas Spartan SR propeller shaft and flex cable require? — After each run, you must remove, dry, and lubricate the flex cable with genuine Traxxas marine grease. The cable should be regreased every three runs or approximately every 15 minutes of full-throttle operation. Regular maintenance is essential for peak performance and maximum drivetrain life, as this component experiences significant stresses during high-speed water racing.
• Do I need any other parts to install this assembly? — Yes, this assembly requires parts TRX10327 and TRX10385 for proper installation. You will also need a 10mm wrench to access the collet that secures the cable to the motor. Your authorised Traxxas dealer can supply all necessary components.
• What is the PTFE washer mentioned in Traxxas maintenance guides? — The 5x8x0.5mm PTFE (polytetrafluoroethylene) washer is a critical sealing component found on the flex cable. If it becomes missing or damaged during operation, it must be replaced immediately using part number 1985 to maintain proper performance and prevent water ingress into the drivetrain.
• How often should I replace the propeller shaft and flex cable assembly? — The frequency of replacement depends on usage intensity and maintenance practices. If you maintain the assembly regularly with proper lubrication, inspection, and drying after each run, it will last for many seasons. However, if the cable becomes frayed, cracked, or visibly damaged, or if the stuffing tube seal becomes cracked or split, replacement is necessary immediately. Replacement seals are available affordably from Traxxas dealers (part number 5725).
• What type of grease should I use for the flex cable? — You must use only genuine Traxxas marine grease, which is specially formulated to provide waterproof protection and superior lubrication in marine environments. Light oils are insufficient for this application and will not provide the protection needed for optimal drivetrain performance and longevity in a water-exposed environment.
• Is this suitable for beginners? — This is a replacement component requiring technical knowledge to install and maintain properly. It is suitable for RC boat enthusiasts with basic mechanical skills and experience working with RC equipment. If you are new to RC boating, consult your authorised Traxxas dealer or contact Traxxas support for guidance on proper installation and maintenance procedures.
