Good Day Gents ,

I have a 58" vee hull at home with a crap Chinese 26cc engine in it . I was going to buy a new Zenoah for it , but a couple of my buddies are talking me into trying aBrushless setup ..... Does anyone have info on what would work here ? I would love to whip the snot outa the gas boys with this boat .... When it was stock it was mollasses slow ! and they teased the crap out of me !

Try this one, it could be your best bet (other than NEU or Feigao 580):

a 580 would not work so good in this big of hull

Thanks Guys .... what about ESCs ? The biggest one i have hanging around is a 120 amp Turnigy . I would think i need bigger ...... And do i understand correctly that i'm to run two 5S batteries to make up 10S ? .... And i assume the bigger the better when it comes to Mah ? Do you know of any video footage  of a boat running with this ? I'd love to see and hear it go !

you would need a Caslte 240A esc for that monster motor..
and yes 10s or more for that motor with 10,000mah would be good!
no video just yet but hopefully this weekend their may be some video of this motor in a Hydro
