I should have said I am running a "CHEAP" sensorless ESC as the Viper ESC never did work well and finally just stopped working. So I bought the lowest priced ESC I could find. The ESC does work with my Hobbywing program box.
The sensorless has a lot better control in the corners and smoother over all. We were running the same setup. I tried the Viper and it did not work out that well.
So looking for a better sensorless setup.
Thanks
