Arrived slightly bent

The material seems good, but my 300mm shaft had a slight bend upon arrival. Packaging could be better to prevent damage during transit.

Smooth operation

Installed this on my 300mm hull. The polished surface reduces friction significantly. Runs very cool even after a long run.

Durable and reliable

Used this for a full season in freshwater. No signs of rust or wear on the sleeve. Highly recommend for standard RC boat builds.

Good quality shaft

Solid construction and straight out of the box. I deducted one star because shipping took a bit longer than expected, but the product itself is excellent.

Perfect for my racer

Fit perfectly into my strut bearings. No vibration at high speeds and the copper sleeve slides on smoothly. Great quality stainless steel.

5 FAQ

Q: What type of lubrication should be used with the copper sleeve?

A: We recommend using a high-quality marine grease or specific drive shaft lubricant to ensure smooth operation and reduce heat.

Q: Can this shaft be used in saltwater environments?

A: While the stainless steel is corrosion-resistant, we recommend rinsing thoroughly with fresh water after each saltwater use to prolong lifespan.

Q: Can I cut the shaft to a custom length if needed?

A: It is not recommended to cut the shaft as it may affect the balance and integrity of the stainless steel core. Please select the closest available length.

Q: Is this a flex shaft or a rigid shaft?

A: This is a rigid straight shaft assembly. It is designed for straight drivetrain setups, not for flexible cable systems.

Q: Is the 4mm shaft compatible with standard motor couplers?

A: Yes, the 4mm diameter is standard for most RC boat motor couplers. Please verify your specific motor shaft size before ordering.
