Re: Electric Surf Board

Thats actually a really awsome thing you are going to do!

Re: Electric Surf Board

What about the lehner 3080? Its a bit cheaper then the 7040 and gets 30 kkW maximum out.
I was thinking to purchase a 3080/10 and mount it in star configuration, then I get 303 kV what whit a 14s batterypack would be ruffly 15k rpm.
What do you think about that motor?
