Okok, got the replacement by banggood. Actually the overall complain management was flawless. The new VESC works fine, you could feel it already during the motor detection. I crimped the phase wires, which was an excellent idea of @sat_be.
The first test run like usual, some abs failure here and there. I think I have to raise stator compensation a bit, the fault usually occurs by 80% duty during throttle. However I als had the v0/v7 option disabled, which might also do it’s magic, thanks to @Giga for his tech support here.

wife’s board is an excellent working setup now, the 8" prop is a good match for this motor. Still punchy and top speed is ok. She is really lucky I had a blast on the water.
Correct, I wish I would have had this much earlier. When I started last year there was only the 6" FR which is way Too slow. I remember asking David for higher pitch prop like 7", but back in the days he was afraid to burn the motors. Apparently you can use also 8" or even 8.5" on these motors. On full duty cycle the motor current is around 90amp which is absolutely fine.
I was bored, so here you have another video from the NL / GER meeting. First one can be found in the “videos of electric hydrofoils around the world” category.
Enjoy

I used small soldering iron. I was lucky because I got this faulty one replaced, so this was a left over. I thought I may can fix it…well apparently this is not the case
Well you tried and learned , best value for me even if something the end is happier ( the way I try to see things even if I believe 1/2 of it )
Always wanted to try soldering with a gun and paste
Yesterday I tried the opposite : solder 1mm copper busbar with a blow torch …
Sry I forgot. It’s double sided taped already. So I did not use additional adhesive. Plywood is around 1cm I think. Should be mentioned somewhere in my build
I had a blast on the water.
