I ran for over 4 minutes, non stop before bringing in to check temps.

The motors have been working just fine, but you have to maintain them. I recommend oiling them after every outing, along with removing, drying, and cleaning the drive cables. We have been running these motors in the 29-inch cats for over a year now on 6s. We find that failure is attributed to lack or motor bearing maintenance. We seem to forget that even though BL motors are "maintenance free" the bearings are not and they need to be periodically maintained and oiled, especially because we are using them where they can get wet.
The issues Travis had are neither related to the ESC or the motor. The boat I sent him was returned to me by Darin Jordan after sending him a production boat. It sounds like the ESC was operating the motor incorrectly, making it sound like there was something wrong with it. Darin didn't report any of these issues to me and it sounds like the defective program card corrupted the ESC's firmware.
