I have a Castle Creations brushless esc that has been around for a while. This particular one is not marked with what the amperage rating is. Is there any way to tell for sure? Based on the physical size it is probably in the 15 to 25A range. The only way i know it is a Castle Creations is that is what is marked on the wires.....
Check it out......i can't remember the name of the street it is on but it is a short ways west of a large golf course on one of the main streets. Can't remember the name of the golf course either....... guess i had better go take a nap now.
