and here some datatest

Note that the temp was taken direct on the esc . The water pump is a car glaswash pump


#3

very nice, monday i will try 2 modified solas propeller and i have a new one coming, you get about 1800-2000w ? i think the solas works better with a 56mm motor …
23km/h is impressive on 100KV with 8s


#4

Beautiful work :+1::+1::+1:


#5

Thank you. It is s 56mm motor. Tell us how it work


#6

What is the pipe on the 3rd picture from the bottom, cooling tube? Antenna? 2 bolts next to it are mast plate mount? Very clean build! !


#7

Hi @Vincentbraillard

Very nice build!
Can you tell me the name of the board?

Greets from switzerland :blush:


#8

Its the same to pacificmeister. A k-race


#9

Interesting the way you have the “canard” stab wing on the front :slight_smile:


#10

The aluminium tube… the output of cooling water loop. thank you for the clean build


#11

Love the build, just about to order my motor etc. Would a larger motor give better top speed and could the same gearbox take a larger motor?


#12

Hello. I use the motor only between 2000 and 3000 watt because I have only 8s. If you want to go with higher speed, just use 12s and a propeller with higher pitch…


#13

Hi Vincent, very nice build.
I’m really curios about the foil wings setup.
Could you tell us more about the reverse layout of Main wing / stabiliser?
Shape, material, dimensions and why the main wing is on the back?


#14

Hi. Thank you.
Sorry but I just follow the manual! And follow this setup!

But it seem to be very stable after some test. Even when the foil go out of water!

Practice in progress… https://youtu.be/_FMgNCxeJKA

Working hard on the remote!

such:

  • remote bat level
  • Board bat level
  • Throttle curve parametric
  • Max power set
  • ESC temperature
  • button for speed regulator
  • automaticly go in sleep mode after 5min of no action (1year battery life)
  • wake up after pushing the button



#17

Nice! How are you waterproofing the buttons?


#18
