No time yet to do it. Summer is for eFoiling 
I will publish it in fall, but there is a video from Lift:
Sorry, forgot to post it here. It is on the E-Surfer Youtube channel since November 
How high do the waves need to be, so that you can start to surf them with the folding prop?
Depends on weight and foil used obviously. I use a 250HA and weigh about 80kg and can surf solid wakes unpowered. So… you don’t need much. But you need a solid wake, small wakes don’t work yet. But I have high hopes for the new 300v2…
Ice water plunge after overuse helps greatly.
