Experience with Flipsky Jet-drive?

efoils – Electric Hydrofoil Surfboards

@Alvestjo

As far as I know you are first here to try this so quite interested in what you discover.

With a Flite prop attached I never get close to “maximum” throttle to launch and even less to foil as an initial drag is vastly reduced so fairly confident this will work for you.

I do wonder what the ride experience will be like. Based on the photos the “output” of the jet will be quite a bit farther back than a prop would be. I’m thinking it might affect the ride in the same way a stabilizer would, perhaps even replacing the role of the stab in pitch control.

I can confirm a jet rides more stable, I had the opportunity to test the audi etron, it is very stable and with a small foil it is easy get to 40-45km/h.

I ride the Audi also, if you fall the Audi glides endless without you. depending on how fast you have been. I do not like that.

The order at Flipsky is placed now. I let you know as soon as I get it delivered!

It will be very interesting do see how more stable the ride with the jet is. I am not interested in going very fast. But stability is nice. Especially since I am planning on letting the kids try it.

But the point of it being too stable that the board will glide long after I fall of, is off course very bad! My current setup with a 65161 and flite prop will stopp almost instantly since the board pitch up as soon as I fall off.

I had a look at the Audi etron jet now. It has a much smaller impeller and slimmer housing. The flipsky jet will have much more drag with the quite bulky housing. I dont think it will glide very long.

My dad did a true jet build (RPM’s around 12.000) , and I’ve tested it.

It defiantly feels different, and it needs more initial input for turning.
Also starting takes a little bit longer compared to a prop as it needs to build pressure to get going.

27

Now Flipsky released the third version om the jet (with max power 19500W):

But it is probably way to big and powerfull for e-foil.
It looks like the same housing and impeller for all of them. The only difference is the motor as it seams om the pictures.

Curious if you have received it yet and could post some photos of what the “jet” looks like😀

29

No i have not received it yet. It was shipped from China last week. It will probably be another week (at least) until it arrives in Sweden.

I will post pictures as soon as I get it.

Thanks for the update. :grinning:
It would be great to see the jet part with the duct removed and if possible how close the blades of the “turbine” are to the inside of the duct
