I agree on this one. Today its i very difficult to define " manufacturer". Iphones are made by Foxconn, so are huge amount of other brands, and other products. The quality of each product has less to do with Foxconn, but the specification given to them. The product is made to specification. You can order bad or good quality, at a price. Even if the iphone is manufactured by Foxconn, probably design is done elsewhere. We can have 2 similar looking motors, branded different, but made to order on totally different specification, quality and performance. Off course they can also be the same. We can not know the deal behind, it can be also so that one of the 2 is the designer of the motor, but produces also same motor(or slightly different) to another brand, …whom knows?
Congratulations. These are really good news.
According to your data, it would be really interesting to find the smallest and cheapest ESC that would be suitable for say 80% throttle (150A peak, 70 nominal ?)
Hey @nickw1881, would you lend one of your nice babies to Virus for a fortnight ?
I too have tried many set ups. Is your motor custom or is it the standard Maytech that
she lists above? If you say its good, I’m sure it is and I’ll just buy it. I’m over all this trial and error. ha
thanks
Where did you see his data?
Just trying to guestimate a smaller/cheaper but acceptable peak/nominal amp ESC (therefore the ‘?’ after the try 
)
I would! @virus let me know if you want to test one out. Mine is pretty small, but I still highly recommend a current control FOC ESC over a duty cycle one. The feeling of torque control is completely different.
I’ve gotten a bunch of motors made in China- I use a company called Shenzhen Saite, and another one called FreeRC Hobby Dongguan.

The motors are all made from the same copper winding wire, the same Japanese bearings, and the same silicon iron for the laminations, and whatever grade ND you ask for. Don’t pay 3x more for a brand just because they advertise on more than just Alibaba.
Nice riding skills , looks like good speed : 35-40km/h ? Thank you for sharing
I love your ESC, do you need my address?
thanks Alex, 30 km/h, 85% throttle +/-, it’s not my most powerful efoil, but I think it’s enough speed to have fun
Whats your amp draw or wattage?
Take un screen shot with the mouse on the line ( gives of information )
Such great efforts.
Thanks for doing all the testing and trials.
I may have missed it but, what is the cost of the Maytech Motor and Esc?
I like what i am learning right now.
Thanks again
Graphs look good. Are they the ones taken from the ride in the video?
I’m still interested to see which prop you tested initially that was not really successful.
Any log on this ride? Rpm data … For cavitation i guess the only way to really know is to put a go-pro on the motor…
Thanks. I’m assuming it was a similar prop to the 7 1/4 x 5 boat props?
It would be interesting to see how well the unit performs with the same prop that Flying Rodeo uses.
Yes, I also use this prop Yamaha with my 1st prototype tp power reisenauer and 120mm diameter.
I think you can improve the efficient with other prop but it’s obviously the motor works, thats the important here, right?
