Any updates?

Wonder if it is possible to order small quantities (1-2) by now?

Either the VESC blew up and got him or the seller found out he was ratting them out here and put out a hit.

I got a mp83mm motor and it lasted 2 days, blew up. It didn't take me though.

We're glad you're ok Ralphy!

Can you share a picture of your setup and the burned ESC so we can perhaps figure out what happened? I've got projects running this controller and I'm curious to see failure modes (which may or may not be related to mfg issues or swapped component choice or whatever).

Thanks!

Giving my time to the electric revolution is done with pleasure. It is no longer fashionable to spit carcinogenic combustion by products in peoples faces as a part of sating daily transport.

Sure
Well the motor I'm pretty sure was defective since the beginning because it got really hot just riding slowly at 15 mph on a flat surface. The vesc had the old 2.16 firmware and I upgraded it to 2.18 via BLDC so I can read it's configuration and reduce the power output. It was way to sensitive powerful and fast.

This is a video I sent the manufacture of the failure. Hopefully the vesc didn't get damaged

How much are their hub motors?
What speed does it go with 12s or what speed did you get and battery voltage?
