Very nice video ! I hope you will continue this project. Does anyone know the rpm of a jet prop of a jetski ? A boat prop is about 2500 rpm I thought
I know that most of the stand up jet skis using 701-750 ccm motors have rpm limit around 7500 rpm.
Thats why someone have to link a few of the 80-100 180kv motors togheter and try combined with hv160. That gives 8500 unloaded. That's perfect for a ice replacement.
What would be the best motor? Is it any calculation? math or physics formulas for jet motor and pump?
