Motor: Flipsky 120kv w/ 12mm threaded shaft. Also ordered their 12mm aluminum prop since it’s just $27
Prop: will experiment with different 3D prints compared to aluminum prop
Controller: Maytech
ESC: Flipsky 60v 200A potted VESC 6.6
Battery: 12S, 1kWh minimum. 2S2P 6S 10,000mAh lithium polymer is the first thought.
Water pump: undecided. Brushless preferred
Board: undecided
Foil: undecided
Everything is ordered besides battery, water pump. I am checking a board/foil out in person next week at a store.
It is… It doesn’t flow like crazy at very low speed but it still flows plenty! It is now well accepted to use water-cooling without a pump. All you need is a small inlet on the nose cone and you’re all set!
The motor, ESC, aluminum prop, bluetooth ESC programmer have shipped. I have already received the Maytech remote control, along with a 1 meter long U.FL extension and a quite nice looking flat (F style?) antenna with a plastic housing and 3M double-sided tape.
They are certainly files out there with a hole for a watercooling hose. If you can’t find any, just drill a hole in your nose cone and place the watercooling hose in it. You don’t need anything more than that! 1/4in tube works pretty well and has enough flow without a pump. Bigger diameter would work even better!
Today I purchased a carbon fiber board with deep tuttle, volume should be 60-70L.
I compared the size in store to the Lift efoil, they are identical volume… Including depth, length and width.
I decided to go with the NAISH Windsurf foil with 70cm mast. Windsurf is good for deep tuttle which is positioned towards the rear of the board. 2019 Thrust | Windsurf Complete
My goal is to have removable mast assembly, will see if that is possible.
Today the order shipped. Tomorrow I will receive some PETG filament to experiment with on the 3D Printer. I have ABS, TPU and PP - PETG is new to me, although it seems very simple to print with. I hope I can get away with ABS for the prints I am doing, but preparing for the “worst” and making sure I can print PETG as needed. My goal is to use TPU to reduce shock, while using ABS for rigidity. I will have to design the parts to take advantage of shear strength perpendicular to the print direction.
I decided to throw my old 3D printer into the garbage. It served 22,000 hours print time over the last 7 years.
-I received new 3D printer. I am tuning PETG, currently success for print. Next, I will test water permeability and sealing methods using the acetone slush, as well as Annealing with Sous Vide hot-water method.
-I received PETG clear color, better for tuning print settings
-I Received NAISH Windsurf Abracadabra
I will begin to order Cable Gland and Pelican Box next.
I will also begin to model the e-foil to provide a basis for retrofitting the motor, mast and Pelican Box
These measurements exactly reflect what the $5 calipers measure. Old Trick: measure inside of the hole, zero caliper. Measure outside distance between holes. Now you have center distance.
Beware that the Abra plate is not compatible ‘as is’ with an efoil use because of the wires between mast plate and board hull. Therefore the hinge idea.
