If you could weigh the hull & hardware only I can tell you why your esc went bad, most likely too heavy. You might be better off with a 6S setup in that boat using a tp pOWER 4050 motor in the 1300Kv range.
Since you have the 2200kv motor, why not try the SF200-220 esc with it first. What prop did you use to fry the 120 esc??
The boat weighs 6 lb 7oz. The prop is a copper beryllium Prather 215. "Has a diameter of 1.6" (40.6mm) and a pitch of 1.56 total 2.5"
Already ordered a
Turnigy 180 from HK 3 days ago. They gave an in store credit for the failed ESC.
I think I'll hook up my watt meter next time and see what it pulls at 1/4 throttle, 1/2 throttle ETC...
There is really no room for 6 cells unless I move the batteries to the sides and use two 3 cells.
More volts with the same prop would reduce the amp draw?

My Phantom Cat by promise hobby is only 29" long but empty it weighs 3.3 pounds!!!! It needs a lot of power on 4S but, it's more efficient on 6S.
Damn! Thats half the weight of his. I tried talking him out of a conversion, but....
