Hello fellow builders!
I am releasing all the build info and CAD sources today. I got lots of requests for STL and CAD files. Please feel free to use and change them for your personal foil project. Build, innovate and most important: Please share insights and changes on this forum with everyone else.
Here an overview of all the available information:
YouTube Build Progress:https://www.youtube.com/pacificmeister
Early 2017 I started documenting my design and build process on YouTube. This was my first public YouTube experiment and I very much enjoy the positive energy from makers around the world. Let’s keep going.
Pacificmeister Open Source
This is the main Fusion 360 assembly which links all other components - directly viewable on web, downloadable in various CAD formats incl. Fusion. Builders can import into their own Fusion projects and have access to all components
Note 4/23/2020 - Sorry, I transitioned my Fusion project, some links are currently broken, so far I updated the REV3 links. Will try to fix the rest soon.
Fusion 360 CAD assembly REV3 - May 2018 (this one is shown in 3D above, similar to REV2 just slightly stronger duckt struts - tested, better than REV1)
Parametric Prop and Duckt - by @Taylor, Video and Fusion 360 CAD file available. My REV2 and REV3 duckts/props are versions I created from Taylor’s parametric setup that works with my threaded mount. Parametric Propeller (my old version part of the assembly. I since updated my assembly to include Taylor’s version (REV2 and REV3) This video walks through the parametric prop which is part of my published Fusion 360 assembly above. Quickly customize things like number of blades, shape of the blades, angles and the shaft attachment sizing. Credits to Nikolai, Emil and Jonas Hiorth for a nicely working prop/duct, I choose a very similar shape.
Custom Masts - This video shows how to quickly adjust the mast clamp to your own foil mast in Fusion 360. The fusion assembly comes with LF 2017 and Axis mast designs but you can adapt it to any mast. Here is the CAD file I use in the video, same components are referenced by the full CAD assembly listed above.
Other Gearboxes - I used the Parker PV40TN-007 in my first build. Here is a Fusion assembly with the Parker gearbox based on the latest setup (Oct 22). I just updated this because I realized that several people bought the Parker based on my old parts list. 3 parts are different to the Neugart setup, the colored ones (red, yellow, orange), also part of the assembly.
What screws are you using for the front nose cone to mast clamp @pacificmeister? My old designs used M4, but I can see yours is much much bigger. Oh I bet there is a way to see it in Fusion 360! Still, might wanna add it to the parts list so people don’t accidently order the wrong thing. I initially ordered M430mm when I needed M440mm (doh!)
I think M6. I’ll dig up the amazon orders and post details. Yes, also in Fusion :). Good idea, let’s add all the screws and little orders to the parts list
In your video you mentioned 35amp to foil. What have you found is the average with your setup both full throttle current to get up on foil, and then foiling current?
Also, have you measured the thrust on your board to see how much can pull?
This forum is going ballistic! nice job buddy, you have left your mark in this world!
Great to see the discussion @VeFoil. A few weeks ago I was on the foil pulling only 20A. But that was without a duct, so it doesn’t count. We do need the duct for safety. Since riding with ducts again I was unable to read the amps on that little display in the box. Sun glare and too busy trying not to crash. Time for data logging. I tried, drowned and killed a VESC already, perfect for logging, I even bought a cheap Android phone to record and monitor everything in realtime with the VESCmonitor app. A bit weak on the amps. Well, for now I am back to my Seaking. I’ll try to keep looking down and report. I don’t have numbers on thrust.
Thank, I think it would help us all to know what current you are drawing to get up on foil as its likely 3-4x more current for that initial thrust in the board.
You should check out the vLogger you can do everything gps, mapping, tracking temp, speed, motor RPM, current etc… Eagletreesystems.com
Yes it should. We have several backers installing it on their efoils, must be a hot topic this week I have had several different makers mention this exact one.
Question about the Foil Fish and stability… what is your experience with foils, is the foil fish tougher to ride than others? You mention you are always crashing, do you always crash on Don’s board? What is your reason for the new foil?
First off thanks pacificmeister for putting this all together, I have been watching your YouTube videos since you started posting them and I appreciate all the time you have put into them in order to share your build. I plan on building one soon.
On the topic of hardware, one of the best places I have found is https://www.mcmaster.com/ , they have great prices and shipping is very fast, I hope this might be helpful to someone sourcing hardware. Thanks again, this is awesome.
Rule of thumb - the bigger the wing, the slower the stall speed (and the slower the max speed too) = easier to ride = less crashing. Higher aspect ratio and smaller wing has higher stall speed (higher max speed) = harder to ride because you are fast and the smallest movement makes big/changes, no time to compensate for errors you make = more crashing. Kite foils in general are pretty small compared to SUP, surf and windsurfing foils. The LF is among the bigger and lower aspect ratio kite foils but still pretty fast. I can ride it up to 20mph. I like both slow cruising/turning but also going fast is super thrilling. I’ll keep testing different foils. Next I want to try a faster higher performance foil, I love fast
I have been following your progress for quite some time, I used some of my International moth foils to make a board a couple years ago before I had to focus on the rio olympics. Nothing beats AR makes the board easier in roll, Ill put some pictures up of our foils.
I just became interested in efoils this summer. After watching a youtube video… Wow! That’s all it took! Im hooked but am realizing a steep learning curve. Thank you for sharing these files! I plan to add anything I develop (that works) to this site as I go. Its been fun following your progress… Great work! Thank you again!
