Excellent durability

I've run this shaft in saltwater conditions for three months now with no signs of rust or degradation. Highly recommend for serious hobbyists.

Exactly as described

Dimensions were accurate to the millimeter. The finish is smooth which helps reduce friction in the tube. Will buy again for my next build.

Perfect fit for my racing boat

The 4mm shaft fits perfectly into my custom hull. The stainless steel is high quality and the copper bushing slides on smoothly without any wobble.

Great value

Much cheaper than buying from local hobby shops and the quality is identical. The 3mm option worked great for my smaller scale model.

Good quality, fast shipping

Ordered the 200mm length. It arrived quickly and was well packaged. The shaft is straight and true. Only giving 4 stars because I wished it came with a spare bushing.

Solid construction

Very rigid shaft, no bending under load. The copper bushing provides good lubrication retention. Installation was straightforward.

5 FAQ

Q: Does the package include the propeller nut?

A: No, this listing is for the drive shaft only. Propeller nuts and collars are sold separately.

Q: What is the tolerance on the diameter?

A: The shafts are manufactured with tight tolerances suitable for standard RC boat couplers, typically within +/- 0.05mm.

Q: Can I use this in saltwater environments?

A: Yes, the stainless steel core offers high corrosion resistance, making it suitable for both fresh and saltwater use, though rinsing after use is recommended.

Q: Is this shaft flexible or completely rigid?

A: This is a hard straight shaft made of stainless steel, designed to be completely rigid for precise power transmission.

Q: How do I install the copper bushing?

A: The copper bushing is pre-installed on the shaft ends in most cases. If separate, it should be pressed gently onto the shaft ends ensuring it is seated flush.
