For anyone using a dual VESC (like the MakerX D100s), make sure you update these settings on the “App Settings”.
You basically don’t want the 2 VESCs to communicate internally (via CAN), and all configs, including input setup and motor FOCs should be done independently.

Any advice on improving reception on a tow boogie.
Biggest issue I have right now is swell blocking LOS and resulting connection loss. No issues if I can pump back out, but if I crash in the surf I usually have to paddle half way.
Will a better antenna significantly improve this?
Other idea would be to mount the antenna on a small pole so it sits higher.
I am assuming you have the “big” remote?
Both Rx and Tx set to RF power of 20 or 22?
And this antenna:
In that case, raising the boogie antenna up with a pole should provide plenty range
TX 22, RX some value, normal small antenna.
Range is plenty, as long as I can see the boogie.
Will the other antenna help significantly with penetration through water, that is no LOS to antenna?
Trying to get radio waves through water always sucks, can’t do anything against that
But a higher positioned antenna will reduce that. You can also just extend the small antenna or buy any 868MHz antenna that is good quality and waterproof
Just note there is many badly tuned antennae, that will reduce your range 
Try to find SWR measurements in the reviews or measure yourself with a NanoVNA for example

Hi Ludwig, have you planned to “introduce” MOLiCELL P45B cells to the Battery Data Selector ?
thank’s
Done. Happy foiling.

Hello
Is that antenna waterproof ?
Yes
20 char 20 char …
Nice ! thank you.
i have 4,2 v delta between Rx and my battery.
Rx read 54.2v and my battery 50v for exemple …
I tried to offset it with “-” didn’t work, and know i can’t even change the values ??
that’s the original values
Something is off with the whole config from what I can see, did you maybe mix Tx, Rx, V1 or V2 when setting the config?
I recommend to do a ?clearSPIFFS on the Rx, then reboot, then do the config again
The ubat-cal should not be changed
The ubat offset put -2 for example to shift the measurement by 2V lower
Both vesc should be in UART? Only the first Vesc is with UART and both are connected to the PPM? I did the configuration as in the graphic from Ludvig
Exactly like GitHub, both VESC PWM and the 1st additionally UART
And additionally the settings shown above in VESC tool if you have dual VESCs
I have 2 flipsky waterproof Mni V6.8 plus… a little nightmare to configure…but now thisni working but only in L6. the control ,is very brutal. I have to find the good numbers
Hmm two separate VESC you just follow the instructions for one VESC at a time and set them up completely independently, no need to check the settings linked above, that is only for 2 VESC combined in 1 housing
Check my channel on YouTube for a setup video for VESC
Make sure you are on remote level 9 or whatever you set as maximum before doing the input wizard

finaly Gotcha! in fact i use a PC version of Vesctool muche more efficient than the Mac version. I could do everything. Thank you Ludwig for the fantastic remote! and the great help! My etow is finally working… just waiting for the good PCB for the nano…

Reception is incredible. Receiver is in middle of the board, board is Full CFK and submerged about 30cm.
Try this with any other Remote

Are you in freshwater? Salt is a different story.
In fresh water I can control a Boogie 10m away with the remote underwater, in salt water this drops to a few centimetres.
Freshwater.
Anyway, starting this way with a flipsky or an other cheap China remote was Impossible, even though the antenna was monted at the Tip of the board.
Now RX and Antenna is burried in the middle of the board.

I believe i had the same problem, i pushed all posible combinations but i suppose not long enough.
I have been testing the data logger function and at the beginning it was working very good but now it is not recording anymore, could be that the memory of the rx is full? is there any way to erase old logs from the rx via wifi? I got auto-logging permanently enabled. (the wesite shows still some place left but the last logs i got recorded are empty and at some point it stopped recording)
Another thing that sometimes happens but so far has not disturbed me is that the GPS speed is stops being shown and the screen starts flashing as if the UART communication between the VESC and the RX had been broken, although the efoil battery status is still being reported…
you got an amazing remote @ludwig_bre !
