sourcing map Boat Model Accessories 3mm Dia 200mm Length Drive Shaft w 3-Vanes Propeller

I have been building a boat for my son, using a toy aircraft carrier as the base. This prop tube seemed to fit my needs perfectly. Its a good length and sealing wasn't a problem. There was some vibration when first installed but that was fixed by adding an additional support (giving 3 supports down its length). I wouldn't use this for a racing model, but for boats with slower speeds it works very well and suits scale models. When you run it fast, it does have a tendency to cavitate but as of yet its not been bad enough to break the prop.

Ran these at 6000rpm for 2 hours and 1 has developed a knocking due to a flat bearing and the other is just starting to grind. Get something that will last!
