Electric surfboard issue with VESC TOOL

Hi there, maybe i can find some help here :laughing:
Im building an electric jetboard using homemade 85mm impeller jet, 8392 200v motor, flipsky 75300 VESC, maytech remote and custom made 16s battery pack.
The problem is that even if I programmed the vesc to run on 16s as soon as I go above 95% throttle is says ā€œover voltageā€ in the right bottom corner.
Also Im unable to connect correctly the remote ; or the remote acts like an on off button and the motor goes up to 100% power strait, or I can control it but only with brakes on and maybe due to this the motor reach 40-45 degrees Celsius spinning in the void.
It seams the only solution for the heating and brake issue is to run the system like a BLDC motor and not FOC… well, Im bit lost, if you guys can somehow help me or needs photos Im here.
Thanks you guys :grin::+1:t3:
