I’m starting my tow build, been thinking about it for some time but didn’t find the time really
Thanks @Jesserosco, @rttn, @Etiennebzh, @ludwig_bre and @jenz for the build info and help so far!
CAD status:
It will be a differential steering tow with dual (cheapest ) 6384 motors and water cooled x-cross 120A ESC:s. I bought the ESCs a long time ago, with the recent x-cross failures they seem pretty sketchy, but i hope they’ll last some months at least.
For the board I adapted a board plug i had already, I originally made the plug for an efoil but didn’t like the shape:
I’m aiming for a low center of gravity and to be able to move the motors freely, so the bottom of the board is plywood, overlayed with some cheap UD carbon.
I cut holes for the motor wires and designed a passive water cooling intake:
I also started on electronics I uploaded a connection diagram here: Bremote connection for dual steering ESC + BEC - #4 by Larsb
As there are only two holes used on the PCB and three pins on a servo connector I’m cutting one header pin off at the bottom and bridging the pin header for the dual steering connector on the PCB here:
I wish i had the skill to change the PCB layout to make it a dual steering PCB without mods, any chances of this happening, @ludwig_bre?
I soldered terminal blocks to the BECs to get a more clean and robust connection:
I also designed and printed a custom box for the bremote Rx and the two mateksys 12s pro BECs:
For the connections i simply used two short Y-servo cables, they were really cheap so wasn’t worth it to buy a servo connector kit.
It feels like this was the complicated part of the build, maybe except for building the Bremote LR, i hope that the rest goes easy
