Thanks four you precious advices @SoEFoil. I clearly underestimated the battery part. I donāt want to pollute @jeffM Ā“si thread with my beginnerās question. For the moment I fight with my PLA mast clamp that exploded when I screwed it. Will make another one in PA/carbon much more resistant.
hello there
just reading your post , i guess you live in a cold country since you need coolant at night ā¦ ā¦i live in dubai when the coledst water is 24 degrees and go to 35 degrees in summer ā¦ not sure if it will work ā¦ ??
i m running water pump from input at front of the cone ā¦don-t like it ā¦i m looking for aluplate to cool down from the mast ā¦
Hi Jeff, tried the link but donāt seem to have access to download the STLs, so sent an access request through Google Drive. Thanks if you have time to grant me download access 
Hi
try now I think itās ok now
Thanks, worked wonders, in the printer now
Hello!
May I also ask you to open the access to the files? I tried asking for an access some days ago, but nothing
Thank you!
This is my āversion 2.0ā for the clamp after it has delaminated at the head of the screws.
If the printed layers are not all compressed by the tightening of the screws, sooner or later it is destined to break.
In the new version 4 threaded bars keep the layers compressed and the stresses do not weigh on them.

Hello,
can some one send me the stl for the gong setup? I donāt have the access to the files but i want to build my first efoil with the gong mast. Please help me. I ask a few times for access but i didnāt get access till now.
Thanks

are @jeffM 's
Youāll have to double check if the pod is for a Gong V1 (110mm) or V2 (100mm) mast width.
I know the google drive folder but I donāt have the access.
I need the files for a gong v2 Mast.
Hello jeff,
can you give me access to your google drive folder for download the stl-files for the gong efoil. Iāve send you an inquiry. Thanks.
Marcel B.
I have some issue with my google drive, I need to upload again the STL

Thank You. It works.
Can you share it again? )
Thank you @jeffM for sharing stls. I am missing one stl in the drive:
I am searching for a duck for 65161 with flite propeller āMighty Bombul-Vihelmo stlā looks very similar what I am searching 
Hi community, compliments to everyone on their work! Iām currently working on my project, and thanks to JeffM, I followed his build to move forward. Iāve made some updates that Iād like to share here for feedback and to see if there are any major mistakes. Go heavy on the feedback. Thanks!
Looks a bit complicated, almost no one uses a waterpump anymore. Passive waterflow from the motor cone is sufficient. I also had a circuit with a forklift relay and a releay that switched it on/off 5y ago. Mine was even more complicated with a wireless remote key. It worked but the more complicted your circuit, the more prone to failure.
If you use the kilovac relay to switch on your system, you have to preload the capacitors of your (v)esc. Otherwise your relay will not live long. The charging current of the capacitors will weld the relay contacts and it is going to stay always on.
I did a preload circuit with a second small 5V coil relay that was in parallel to the forklift relay and connected the vesc to battery plus through a 5W 510 0ohm resistor for 5 seconds to precharge the caps. After that time, I switched on the main relay and switched off the precharge relay. This was done with a separate arduino nano and arduino relays with drivers.
When the small relay failed the 2nd time, I removed all those relays and replaced them with XT90S antispark connectors. Les complicated and less weight.
You also have a 150A circuit braker on your schematic. Most of the cheap chinese ones used to trip at around 60A, no matter what value they had printed on them. Better use a 200A fuse, I use a midi Otto which is the smallest one rated for 58V I coud find. If you disconned the battery when running the motor, your esc can get destroyed from the energy in the
motor windings.

How have you found the anti spark connectors ? and what is your typical current draw through them ? I was going to put a precharge board in my project but space is tight and the off the shelf units seem crap i took delivery of a Maytech last week that was dead on arrival with one of the supply leads missing.
