So I had the time to test the filament cast ( PolyCast)
bought here :
very easy to print it, more easy to remove with the temperature, but I have pretty the same result
How do you power the Maytech receiver ?
I powered the maytech receiver by the 5V VESC (pwm)
You mean, your receiver is just connected to 5 wires: Bat, Mot, Pwm, Tx and Rx ?
I got a crazy idea that should be cheap and effective: in addition to cast aluminium prop and ESC block, what about making a front wing with 2 half molds (flasks) ? Then there is this sleeve on the wing to fit on the fuselage that the Gong Hellvator or brands like Axis don’t have.
Does anyone here know who made the efoil flipsky.stl ? (the nose cone in post #12)
I would like to have the water inlet part (part that connects to the hose in the mast) moved a little bit more backwards. Unfortunately I can not edit this file.
Anyone here who can do this for me?
Thank you.
but the waterintake is not from me.
I downloaded the STL and take a look.
I think it is totaly on the wrong position.
Or the tube go outside there and looking in front, but than zou have problems with the screw.
Did some one print that adaption and test it?
We printed it. If fits perfect. Only problem is that the exiting hole (going to the hose) is to far forward for our mast.
It is like I wrote before.
The modifications are not from me, I think it will be not working and I also not control the position to the mast.
I am in the middle of my 2. build. I have a water cooled Flipsky and want use theme.
So I need to modify my clamp.
When I am ready, I will share my results again
it works for me 
I placed the position here because my pipe don’t exit to the mast
I fill a cavity inside the mast and I pump the water
Like that the pipe is vertical in the mast and has no angle at the exit of the mast.
but it’s debatable it is one solution among many others
do you use a pump? I would like to drive with ram pressure.
Yes in my V3
with this solution the pressure is not high enough to remove the pump
I tried and I only had 3 drops
Okay, this is what i want to say.
I want a water intake and not need a pump, with your solution it is not possible!
But, I like generally your idea. I think about if is it possible to use one of the screw holes for a small tube go outside and the back pressure is enough for the water circulation.
Generally I not like water cooling.
In my build I use a Trampa inside a Alucase on a Aluplate. It is more than enough for cooling.
I have a Flipsy FSESC 200 and want use it, but he have water cooling connectors, perhaps I sell theme and buy a VESV for passive cooling 
Can you not pull/remove the FSEC 200 from the aluminium casing and add an aluminum plate to it?
Perhaps, but I bought today the HGL Tech 75/200
I will save the FSESC 200 or sell it, don’t know jet
I made a small closed cooling system for the FSESC 200 and it works great. Probably not something everybody would want to do but it’s super simple.
If you decide to sell your 200, let me know. I need a spare as I don’t trust any of this Chinese gear.
Please, I want some pictures from your solution
Yes, me too. Please share. I would also like to know if it’s possible to cool the 200 fesc without water somehow.
Thanks
Here’s a picture. I keep my FSESC in a plastic compartment because my board leaks and I want to keep the electronics dry. Obviously, if you have something to enclose the BT/radio module in you could dispense with the container. For the actual cooling, It’s just a little bit of plastic tubing and a small 5V pump that I run with a 9V battery. This circulates the coolant through the FSESC and then air cools it in the tube. So far I have run it continuous for 40 minutes with zero problems.
Sorry, I didn’t realize how bad a picture that was until just now. I’ll get another tomorrow and repost.
