hi all
i am struggling i have built a 36" multi hull known as a monza
i have a submerged drive in it tried with a 35 mil prop and running a 3505kv brushless motor
and have completely blown almost caught fire 2 speed controllers
1 was a mystery 80 amp water cooled speed controller
2 was a jeti hacker navy 3 opto 99 i believe (cant read as it in cinders)
both times i was running 12 cells
any ideas before i rip it out and stick either a bbturbo 12v
or a 8.4 v bb turbo
both times motor has also been water cooled and boat has been completely dry so know leakage letting in water and water cooling working properly
many thanks in advance
