The 2650 on 4S is not really appropriate.

That said, there is still the issue that the Activ8 only runs sensored.

Maybe Novak knows something about running sensored that other Manufacturers don't, but the other manufacturers will tell you if you use sensored mode only, the motor will run hotter. The 1/8th Tekin ESC does not even have a sensored-only mode.
