RC-Speedboat Water-Propeller

These are highly engineered speed boat propellers to achieve incredible speed and efficiency.
Characteristics:

- Extremely high pitch → incredible speed

- Increasing Pitch towards the trailing edge → more efficiency
- higher blade angle → less propeller slip → better force directory and acceleration

Technical details:
- Max Pitch: 70mm, average 55mm (distance travelled per revolution)
- 30mm diameter

- 2mm and 3mm axle

- Clock & Counter-Clockwise

Which to choose?

- 2 Bladed Propellers usually deliver the highest speed with best efficiency, but in case you need more pushing force (not speed!) you might choose bigger or

- 3 Bladed Propellers to accelerate a bigger mass faster. Propellers with even more blades lead to worse results in RC use cases.
