Read the forum friend. You’ll find more than the info you just need.

yes i know, but i didnt find any thing about 775 motors
or what type of motors i can use in a list

4

You can use this motor with a very small jet like KMB JET28
Take 3 and it will not have enough power to :surfing_man:
Therefor nobody is using this


5

its very small and also its online shop, means i cant buy it in my region
i just need a list of useful motors for jetboard😱

6

If you can’t buy anything online it’s quite hard to build a jetboard or efoil - what region are you from?

7

unfortunately we are under boycott by usa,
so we cant buy anything online from shops.
in iran we have many shops but they dont have all types of motors
so i just need a list of useful motors to creat a jetboard, maybe i find a motor in the list if existong in iran

The motor is only one part of a esurf - you need a jet, esc, batteries and so on

How fast you want to surf?
Take a look at Lampuga, Awake, Jetsurf and so on - 8 to 15kw is “normal” :surfing_man:
Make a efoil - it’s more fun and needs less power.

But most motors coming from China. Also not possible to buy those things?

10

for efoil, how much kw is necessary to fly!?

for jetboard 20 km/h is enough for me

all parts for jetboard or efoil is ready, the only problem is motor and kw😱

11

we are under boycott from all of the worldđŸ€Š

so we dont have any online international pyment method

Sorry

I know one, he is from Germany and often in your country. But I meet him in summer next time.
Perhaps he can help to take some things to you.
But I don’t know it is possible with the Bordercontroll.

If you have a efficent system you can fly with about 1.2kw - to start you need about 50-100% more

If you have a efficent system you can go 20 km/h with about 4-5kw - also depending on your weight

You have some pictures to show it?

Try find a torqeedo 1003 gear. They are 8:1 and have a shaft that can already take a prop which works very well!

Look at these guys. All kind of weird combinations with small cheap 775 motors. I’m impressed with the ideas the show. For a jet board maybe you do not an esc controller. You want max power. So just just on and off would work maybe. What is your weight? With a jet surfboard it would take a few kw extra between an 90 kg or 70 kg person.

An efoil should be doable with 775 motor. Maybe 3 in stack. A few seconds 2500watt and than fly with 1200 watt

I would have no desire to invest so much money in so many engines, in addition the transmission losses and the short life of the engines should be considered.

There are good foil motors from $ 70 that work. ESC from 60 dollars, and that can do more than double the performance than 4 x 775.
