So I installed the fan on the esc, took endbell timing down to zero, and went to 87/18 gearing. The esc has zero timing and the DRRS is set at level one.
Took it back outside, car was quite a bit slower and it did the same thing, ran it for 5 or 6 minutes and the esc shut off, this time the esc felt warm but not hot.
Not sure what's causing this, I might frill a few holes in the body around the esc area. Maybe the motor is putting out too many amps? Any ideas?
The SP GT2 LPF manual says that 5.5t motor is the limit you can use on a 2 cell lipo or 6 cel nimh. So you can be pushing that esc to it's max.
Another thing you can check is your bearings and all driveline looking for binding or resistance as this can easily bring temps up.
