New Build from Slovenia


How you will bolt the gearbox to propeller mount ?


You mean this?


First part of assembly was a success.
Now i need to put it in the housing but dont have anymore time today.
Will continue tomorrow.


Good job seems like there’s no vibration


Yeah. I made everithing that turns H7 tolerance. So it should spin perfectly.


The foil from gong shop has arrived today. That was really fast shipping. From France to Slovenia in just 3 days. The quality is very nice on first look. Was pleasantly surprised.
@Manu thx for the 3d model for the clamping. This will come in handy.
And thanks to every one else that helped me make this decision.

Now i can start with the board shaping.


Board shaping complete. Took me 2 hours with chainsaw and scratch paper. Tried with grinder but it melted the XPS…
Not totally pleased, but for my first board shaping it should be ok. :slight_smile:

Tomorrow i will probably get the 3D printed clampings so that the motor assembly should be complete.


E-motor almost finished.
I only need to reprint the 3d printed parts since they are made out of PLA because it was made for testing. I will use ASA. Its more temperature resistant. And gives me more accurate printing.
Also i will use a bigger propeller. So i will need to change the 3D models a bit.

It fits perfect on the mast.
Need to buy 2 screws to screw it on the mast.


Any1 can give me any tips on where to position the foil on the board?
I was thinking of making an aluminium part where i could move the foil for like 15cm from front to back.
Any info is appreciated.


30 cm from the back From the board to the back of the foil seems to be what many do…


thx for the tip. 30cm it is :slight_smile:
Now i just need to repair my CNC machine…


Finnaly got the cnc machine repaired so i could make the hole for the cover. First time i machined xps. It machined like butter
And It was super messy…
The next board i could definetly machine whole on the cnc machine but i would need a very strong vacuum so that i dont have to clean the whole machine afterwards as this stuff is like snow. You just cant get rid of it :slight_smile:


For the Foil mounting sistem i have decided to go with this.The 90mm bolt patterns will fit ideally. The only thing that wont fit with the Gong foil are the M8 nuts. The Gong foil has M6 which can be fixed pretty quick. -->


Scratch that previous post. I found the original foil mounting plate on the Gong Foil website and its only 50€.
Luckily i did 1 last search before ordering the other 1 :slight_smile:
