wats up guys , this is my first hobby grade r/c boat and theres a few issues.

the first is i think my esc needs programming , when i give it full throttle and hold it the boat will go about 1/8 throttle for about 1 or 2 seconds and then it will go full throttle...almost like a timing..

the 2nd is im not sure where to put my battery , front , moddle or rear?

the 3rd is someimes when i go to take off , apart from the 1st problem occuring it sometimes gargles up real bad like the prop isnt in the water , and the prop is adjusted as far down as it can go... it also does this when i try and turn at speed.[:@]

it also spins out real easy too but i think i needa turn my steering trim down , lol.

all this is nothing without info , its a brushless mini sea predator on 3s lipo , cattamaran style. , heres a pic , cheers lads
