@jeffM great thread here. I have a few questions for you (or others) as I embark on my first build.
Hi, this is the XL curve wingfoil ( carbon aluminum) you will find the link in my excel file above
Part list plus wiring diagram = good job ! 
Does anyone have the flipsky motor 12mm file in .step ?
18650 build finished, and tested today, very Happy.
it’s samsung 30q 12S/10P with BMS
tested today with the Autumn colors 
ride time : 1H15
max temp : 45 C
Amp average : 18A
swimming fins and other prop into the bag
And I lent my E-foil V3 to my friend and took back my e-foil V1
18Amps?! What motor and wing are you using?
Flipsky 120kv, Gong XL Curve (1st post 
)
If I analyse correctly, the 20+% amp gain comes from a more triangular prop blade shape:
@jeffM, I find really interesting that your kill switch did not show any kind of damage on your V1 and V3 ESCs.
To know what to expect from a Gong XL Curve, what are now your take-off and max speed (even if speed is not your goal) ? Did you find/borrow a L or M Gong Curve to test/feel differences ?
Compared to the direct drive simplicity of the V3, what differences do you notice when you ride the geared V1 efoil again ? Would you build a geared efoil again or not worth the extra hassle ?
ok, the XL explaines the low current rating.
Gong doesn’t stock any xl wing anymore I have been looking for it for a while now
with the curve I don’t no exactly the speed for the take off (I will look at my GPS for the next ride) I think 13/14 km/h and Vmax 25km/h after there is a whistling certainly due to stab, and I don’t like the noise when I ride.
Never test L or M gong curve but I ride with a ketos foil with cruiser / wave XL and fr2
and the XXL curve start really earlier. But I tried it on a kitefoil, and it’s not very fun “pleasant”
it’s too big.
V1 more power but more noise, and more complicated for construction.
if i build a new one it will be with an engine like the flypsky
Could you share current pick to go on the wing in this config and yours weight? Your board still 24kg?

=> the gain 23A to 18A comes : new prop diam 132mm old 125mm
and i sanding the trailing edge (more sharp). I don’t think the shape improved
efficiency. Because I tried to do the same 
but you’re right it’s not realy the same
it’s more triangular but it’s exactly the same blade.
On the first propeller I had done a “dirty job” , I had a slightly different blade
look on the picture of the lower blade
and also I sanded the cone at the base of the blades
I look forward to receiving the aluminum propeller from FR to compare the efficiency and install the swirlcone from cim96dm7
@jeffM did you ever have to widen the hole in the back mast clamp? I have 3 8awg wires that I am trying to fit through this back mast clamp from the flipsky motor and it seems to be too tight of a fit.
No I didn’t need to widen the hole
it’s tight but it works with 3 8awg cables
I got the stl from the forum
if i remember correctly it was robert’s creation @nice2cu
he can answer if he reads this post
Hi, which one you are using?
I am using the flipsky 65161/gong mast mount. My motor has these connectors on the end that are the issue, were these connectors on your flipsky motors?
sorry but you must cut off the plugs.
You will also not have luck when you want to thread through the mast
