Hi guys, I run two efoils for more than 1000km already but I did never measure the efficiency. Yesterday I did a test with 2 different props and 2 different foils.
The best result that I got:
Average speed: 20km/h
Rider + board weight: 95kg
Foil: Cabrinha high rise speed
Motor: flipsky 120kv
Prop: 7 1/4 x 5 turned down to 145mm
Esc: swordfish X300A
Would be nice if more people can share there results. Efficiency in Wh/km please.
