Was looking for some videos on Efoil and came across this one :

Interesting as it is nearly a copy / paste of what we already use on efoil. Also, if you look closely, the prop seems pretty close to te original PM’s one with 5 blades :
My bet is that they are using kind of 5065 BLDC motor as direct drive to get 10kg of thrust @800W. Also, pay attention to the fact that they are using a third generation Blheli esc along with a controller, which is what we are using on drones today. Which also is what @stijnhof is planning to use on his board. This is definitely an interesting build.
Would love to hear your thoughts about a similar “compact” build for foils
Have a nice day and happy new year everyone !
