That’s them!!! They totally look like the supplier for the 83100 line Alienpowersystems carries. Bruno couldn’t make the meeting today so i was left with continuing the search for new options. I’m straying from 83mm over to 100mm in consideration of the single jet.
Seems like Flipsky is receiving their motors from them too?
In any case, the flipsky 63xx motors for esk8 look awfully similar.
They are one of the motor manufacturers for a lot of esk8 motors.
What about an 80100 motor and an 80mm jet?
Or is this jet to large for this motor?
I don’t want to go any bigger then 80100 for the motor size because of space and cost, but I don’t know if a 60mm jet will be enough for good speeds
Btw I am not sure whether the 83100 (the watercooled version of the 80100) would be a big improvement over the 80100 when staying under 100 amps.
The 80100 is going to be whats required from the 65mm jet i doubt it will do for 80mm but i have no idea. The problem with the 80100 is the power limit. It’s limited to 7000w if you use every bit of it’s power(we wont). You are hearing most board manufacturers are having 12kw power ratings to achieve what they do. So if you want two 65mm jets you could totally run the 80100. I want a 12kw single-jet board, so to the 100mm motors i go.

And on what jet size?
I don’t know yet. I need to test the load of my jet at and near 20k rpm. At full RPM my jet theories to hit 90lbs of thrust for around 5-6kw. I can begin increasing the pressure (but i think its already 60psi at full speed) to achieve more speed/velocity out of the jet and that will increase power and load. Perhaps to the degree where it makes 150~lbs of thrust at the same size with the right load.
The blank is almost done. The tuck and tail still needs to be shaped. We are going to leave the rails as is. It’s giving the board a kind of stealth look.
The front bottom part has a concave in it. About 1/2 it splits into double concave. Not sure if this is a good thing or not.
After this we will cut the jet and battery box.
It is fun shaping it, but wow… what a mess…
Sharpen the rear section of the rails like a surfboard. They will give you more “bite” when you turn and improve your turning. Look at the shape of the rails on the jetsurf boards.
Picture of the board is from the top. (Deck).
And yes that is the plan. Sharp tuck on the rails for the last 1/3rd of the board.
We have not decided if we will put fins on it.
I do not have any on my old board.
Ah I see. Yeah put some futures fin boxes in. Fins are a huge plus when turning and you can also experiment with different sizes.
Yes so true about the fins. but where do we put them?
Same with the foot straps. We would love to put some on… but again. where exactly.
So back in 2018 or 2019, I watched a video of the lampuga boost at the boot show where they claim they had a huge thrust of 100kg. Yet the board was advertised to be « only » 55kmh.
Makes me think you won’t be able to reach 50kmh with this setup. What’s your thoughts ?
It is not that we want to reach 50 km/h, and it was a wild guess.
BUT. With the setup I have now I am hitting 30 km/h. and this is with a 6S lipo.
The board we are using (an old cutdown surfboard) is not made for this speed, and the jets are foamed into the board (not really flush with the bottom).
Besides this the center of mass is way off to the back causing it to be “tail” heavy.
One thing will be sure. The new board will go faster than what we have now.
And… no more 6S, but 12S.
I’m not sure but 100kg seems awfully overly-optimistic. Jet-skis make around 400kg on average.
That website boasts 58km/h with what they say is 14 horsepower. Guess how many watts 14hp is… 10,500watts. So yeah we can do it with the 12,000watt design i’m after 
Also side note- look how tiny the jet looks on their site. Thanks for mentioning another board not heard of that one.
Like the look of that. Now I need to find fin boxes (whatever they are called).
Any suggestion where to get them from?
These are the ones I use in my surf as they are quite a bit stronger than the FCS.

Ok but you need to provide rider weight when speaking about speed for a jetboard. You said earlier you were 60kg. So you are hitting 30kmh with 60kg which is great, but what about heavier riders ? I mean there are very little people weighting 60kg here (yes I know jetboardcologne does but still).
Have you tested your 6S setup with a heavier rider ? What was the outcome ?
Honestly I tried to find this video back and couldn’t, but I really remember they said something like this.
Yes they are using a 10kW motor (Lehner motors).
Might look tiny but is not. Look at some videos you’ll see. I remember I’ve seen someone speaking about an impeller in the 90mm range for the boost too.
