love it! do you prefer 12s2p vs 8s3p? I’m about to start my battery build and trying to decide between those. Thanks!

And vs 10s2p or 10s3p or 12s3p ?

More voltage, less amps. 12S on P42 is nice because you have more speed and things run cooler BUT you already have lots of torque/speed on 8S3P and you get 45A constant more on 3P vs 2P. You will not be disappointed on 8S3P.
My advice is to avoid VESC based ESC. Get a traditional ESC. Way more torque.

go for HV3 - no doubt

yes, back to back. still awesome but less top speed
Foildrive is dropping their underboard version on 3 November… gonna be interesting to see how many forum ideas appear on it

likely, which is what I would do :
- box inline under the deck (between baseplate and board). This is necessary for ESC cooling and also neat setup. When I was trying it, I noticed that we have 9 cm width between the USBOX rails which is more than enough to have the pack inline and benefit from the space left under the box while having a better center of gravity.
- removable packs without removing the mast; that would be a no go if they don’t do it… imagine changing the mast to change the battery pack.
- plug / unplug the motor directly to this box for the ease of setup
The overall logic would be a natural progression to the existing system which his a box, a remote and a motor attached to a mast. nothing rocket science but a very nice addition to what we love to do : foiling !
If foil drive don’t do removable packs they are insane.
FR is coming with a completely new design with removable packs and a brand new remote. The foil assist market is about to seriously heat up!
Super interested to see what FR come out with.
By the looks it’s a mast system, maybe with a battery built in up the top.
That looks like 6s. Doesn’t look like 8s will for in there. Looks like you might be able to switch the battery with those clips.
Hmm I think I would much more prefer a kind of back pack solution.
Having it mounted on the bottom of the board does not seem to be big step forward compared to the box on top.
You still have the weight on the board and the size of the box is not an issue on regular boards.
yes, backpack is awesome because you have full board control, almost no weight apart motor pod and motor.
but let’s be honest, for safety reasons FD will never propose it to the mainstream. Although my 11mm osculati sea rated cable is solid, strong and flexible + connected to a locking system in my backpack on 5mm carbon plate with 3DO material… it’s not a board leash. Yes it does the deal very well but not for a consumer product.
looking at your photo, their layout is interesting because they went the easy way which is to leverage the space below the mast and the available 9cm on us rail box to put the cells. This also open some field to have different enclosures on the front to accept different battery size.
I’m still puzzled to see them using likely MR60 connectors which are rated for 30A/60A max current.
It’s not a rocket science integration but there is little space and few options to innovate here. It’s not looking as a finished product which is a big step forward and no more “DIY garage stuff”.
In fact, they just improved their v1 product to have better cooling + and seamless board integration. they are also partnering with AXIS or others to have custom cut mast which is win/win.
I like it, but what we do here in DIY… is just another game but kudos to them. Doing DIY is one thing, make it mainstream is just another level.

Is this inside their housing?
The FD Slim looks like its 6S2P for the size above. I would imagine they are using the P45B cells then. They are definitely moving away from a modular system for any mast here.
I don’t know but I believe they will go for something like that for a quick plug and play motor to electronic box solution. I don’t see them using a custom connector, reusing what’s already there.
the any mast solution is still valid. the photo is showing a specific collab with AXIS but I’m sure they will have a “normal/any mast” solution with the motors going as they are channel today

The channel is running on the actual FD box and not on the mast. This allows any mast to just have a hole drilled in the baseplate etc.
I’m not sure they are even bothering with a connector. I think they are just using a fixed cable at a certain length…
We’ll see on the 3rd what the exact specs are… The one thing I would love to know is how FD have overcome heating issues with the VESC for full throttle longer than 30sec.
HV3 : is it this one ?

How do you deal with the BEC with a 12S battery ? (most BEC use max 6S input)
