well im now with the many of you who have blown one of these latest motors/esc's up. This is in my p-ltd rigger. I was running a turnigy 45c-90c nano tech 4s lipo and the aquacrap 60amp esc and 2030 motor. I got to the 4th bouy after taking off from the shore on my first heat yesterday. I was running a stainless prather 220 and this is the aftermath. Motor and obviously esc is gone.

From the looks of things the esc had a failure internally and it fried the motor as well. The aluminum cooling case on the esc has holes that are melted through. Im just glad it didn't set the brush on fire where it ran into the shore and my battery is ok.

and there was no water inside so I know that didn't cause any of this to happen.

My initial thoughts on this are going to go completely against popular opinion (which just means that a lot of people THINK something... doesn't mean it's correct)...

Not enough prop.

It's pretty amazing how amps drop and things cool down when you actually get the boat running efficiently.

Either way, it doesn't sound like this is a "motor quality" issue. I'd suggest that at least 80% of these failures people are having aren't. But, unless you are running data logging and can review the conditions, I'm pretty sure there won't be any convincing the majority out there of this.

This is what's left of my electronics. I believe it was a esc problem looking at the crazy lump and hole where the aluminum casing/ watercooled sleve melted but maybe it was a motor issue idk.

Darin this was the first time out with this boat so I wanted to put something that was smaller but not to small and currently on my p-ltd sport ive been running either a x442 that's cupped up or a x440/3 that been cupped and haven't had any issues with amps or overheating. I think that this esc was just done. And 2 it lost radio turned left and drove itself into this nice dry bush along the shoreline. So I believe the esc shorted out before it shorted out the motor.
