What were the ESC temps before they blew? Is the water flowing freely thru the cooling system?

Motor ever get wet ?
Could be a bad motor with a short, And its shorting out all the esc's,
Take a multimeter and check each wire to case or can of motor for continuity.
Should not have continuity.

Good luck.:tiphat:

Bet the motor is bad. Grab a Feigao 540 13L...........only 59 bucks.

I wouldnt say better, but not a bad alternative price and performance-wise. Some people bash Feigao a bit, but you would be suprised at how many members on here own one............i got three myself and they are still kicking strong.

The UL1 motor is a bit overkill for an SV hull................the 13L would run nicely in it.
