Smaller ESCs can handle big voltage if built properly. Size of the ESC typically tells you the amp carrying capacity. I suspect the size is smaller not because of lesser voltage but because they simply needed to fit all that equipment in a tiny space. That’s why plane ESCs run higher voltage with a smaller size because they are tight on space and don’t need amps, they need voltage. Its odd to me that this ESC is this small but runs 90 amps, whereas the outgoing dynamite 60 amp is about the same size But, if Castle Creations tech support has taught me anything, it’s that ESC amp ratings are about as truthful and honest as lipo C ratings, which is to say, not.

You and about 5 other people, glad I could answer the question, I was curious about it as well

@@IRONCLADRC this is why I subscribe, you give a shit about your subscribers and it shows

It’s not a misprint. It’s a 60 amp hobbywing 1060 based esc. They rate water cooled esc’s higher because of the better cooling allowing it to run at a higher amp rating.

@@FEboats Well misprints do happen, the owners manual for the AЯRMA Kraton 8s says that the motor is a 4985, 1250kv, but it also says it’s a 4685 just like the BJ42 although it has a kv of 1250 and the BJ42 is 1350kv, if you can touch it with your finger and not get burned, then it ain’t too hot ! Run what you brung comes to mind.

@@scottdearmond5532 I understand. I have those trucks and that boat too I saw it. The Firma 90 amp literally says 1060 in the part number.

@FEboats could be wrong but 1060 is the part number. Not to be confused with a 1060 brushed hw esc

@@IRONCLADRC And the motors are different part #’s between the BJ42 and the AЯRMA Kraton, so I believe 1350kv and 1250kv to be correct, they are same physical size but the armature is wound differently. 👍🏻

To many!
