Hi all i took my boat out this morning it was my second time all together, yesterday i ran the boat and used 1 full set of batterys gp3700 and all was fine just a little salt water. i took the boat home to check all is sealed and give a good clean out.
today i did exactly the same thing and this time no water nice and tightly sealed but half way thru my fun the esc blew.
i took the cowl off and a great white (not shark) smoke blew out and i found the wires from the esc to motor had melted off & the shrink wrap had also melted, after i got home i disassembled the esc and found it was completely burnt
WHY?
the setup is mhz flash hull, feigao 540/9xl castle creations barra 80/ 12 cells with a 40mm carbon prop.
i didnt bother to stop and check for temp as i presumed that this is underdone with prop size and so wouldnt overheat.
the motor is watercooled but the esc is not
i was not running full speed but varying the speed slower in the corner but was not able to go all out as it was too bumpy in the straights.
I dont understand why the esc burnt like that as far as i can figure the whole system is underdone can some explain what went wrong?
is there a better esc i can use that comes with cooling built inn that i can run at slower speeds if needed,? if that was my problem.
ps. the reverse was off, and starting power was low,
Thanks all for your help in advance.
