The Cyberfoil build

nice built! , looking forward your result using the vesc :wink:

Hi,

Nice project ! I’ve received exactly the same foil last week and I’m gonna try it soon. I had the chance to work with a Lift foil a week ago and I took some pics of different details… It could maybe inspire someone…

I would love to know the diameter of the motor tube if you get a chance again! Rumour has it they are running a direct drive motor.

If that is a 170mm foil the diameter of the tube is just 50mm. Can that be right? @Jezza @Carpi

Listen to @Flying_Rodeo @ 6:48 stating the Lift has direct drive. No gear box.

The next question of course is what motor are they using?

True, Lift use no gearbox. Just direct drive. I did not mesure the tube they are using but it looks a bit bigger than mine… probably around 63 or 65mm. Their engine is pretty long and has an impressive torque.

I would say its 60mm - 65mm if I guessed. I think they most likely used the outside of the motor as the motor housing. It would make sense to design it like that for cooling purposes and eliminate the need for an extra tube.

With some good design we could probably do that with the existing 56mm motors with a good custom gear adaptor.

The board blank is finished. Really sleak! Now time for some glass and carbonfibre.

Looking great !! Did you use multiple blocks glued together ?

Yes. 6 pcs of 1200x600 blocks.

What is the thickness of each block?

Do you have any idea of what motor they use? Taking in consideration the length of the propulsion unit they are not using gearbox.

The thickness is 100mm.

Reading this forum my conclusion is that nobody knows for sure. Obviously it is a inrunner direct drive setup. I am just guessing here but propably custom made for this application around 100 kv and about 10kW of power.

Maybe it is similar to this motor:

Hi, Did you by change saw where were located the water intake/outlet for the wate-rcolling tubes?

Epoxi curing the Scandinavian way. In the sauna. (Yes I just might put vacuum bagging equipment in there also).

This particular piece is going to act as the on board foil mount. Two aluminium 20x10x2mm profiles with two layers of glassfibre next to the aluminium for galvanic isolation (thank you @Mat) and two layers of 200g carbonfibre on each side. Sturdy as h**l.

My wicked board is almost finished. Some hotcoat and clearcoat and its done.
