Morning JeffM.
Fantastic job you are doing and thanks for taking the time to share with everyone.
Your original 23A prop I think you called it. What RPM where you spinning it at. With the 5” pitch I am looking to spin mine around 4000 RPM to start off with.
Hello! I tried contacting you by pm, I would be so happy if you could share the step files for the gong-flipsky clamp system? 
Thank you in advance
Hi, @Fabien_n the mast clamp I’ve got works the same way as FR’s one and needs to be machined out of aluminum, I’m not sore it will be of much use to you? Printing it will not be strong enough unless you modify it a lot.
I actually need it because I want to try CNC’ing it in aluminium as well, and they need a step file and not a stl.
For the mast pod in STEP or STP format…
'Efoil V3 - STL files for Gong foil and Flipsky motor 12mm - Parts list - Schematics - #79 by jeffM
@nice2cu should have it. If you go the forced flow water cooling way, @f16model, @Ackermann, @jnobile, @wushbush might have the Gong + Flipsky version.
Is it necessary to install 8 bolts for this plate. What is diameters? Thanks in advance for your answer
Hi jeffM,
why did you change the circuit breaker 150A for a 200A fuse? is there any advantages in using the fuse?
Can you please share the 3d printer settings for these STL’s.
Im interested in the infill ratio?
Did you use carbon filament, are there any other strong enough filaments i can use?
Thanks!
I print it hollow.
I used 3 or 4 layers for the border.
After I drilled on the layers that looking together when you mount it on the mast some holes and filled the clamps with Epoxy mixed with bits of glass.
Because I want it nice and more stable, I laminated it with one layer CFK.
Here you can see how I laminated it.
Thank you for the response!
awesome! thanks @Manu for the reference
Jef, how did concretely, with what tool ? did you drill the gong mast? if you had to choose, would you get another foil or stick with the gong ?
The new gong is much stiffer than the V1, the feel underfoot is better and more incisive.
manu, we are talking about this one ? L size (I’m 72kg) - 85cm mast

hey Jean Francois,
Encore merci, tu imprimes comme cela (avec support ou non?) 0.16mm 100% remplissage? Je pars sur du PETG. Sinon je vais utiliser du water cooling mais sans pompe, tu penses que ton design fonctionnera?
Salut,
I printed with 100% in ASA . this design work only with a water pump
if you want to use it without pump, you need to move the hole on the front of the nose
thanks a lot Jean Francois. You’re a star.
Do you know if the ready to print STL is available somewhere with the hole in front of the nose?
Keep it up.
Last but not least, which foil would you advise? I’m still hesitating with Gong but they are cheap, which one would you go for ? Allvator v2 L? (I’m 1m78 / 72kg) or more a HA one ? I wish I could use my existing kitefoil (but it’s a 1200cm gravity fone / kite) or my wing foil (AFS, but the mast is so far WAY to expensive and full carbon)
My advise : Gong V1 65CM alu with curve XL
V1 alu vs V2 : cheaper, lighter, good enough for an efoil
the V2 is better for Wing or kite
If you want a very light Efoil you can choose the gong V2 carbon 70cm
(it’s my new project 
)
I may add , v1 mast is ok for 72kg , but with xl wing and 98kg ( at the time…) , I bent it on a tight turn
