Appreciate and agree SY ching.
I started with HW EZrun 60a + 8.5T sensorless 3 months ago. I used 19T pinion gear initially and increased one T when I felt I could get control of the car reaching 23T now.
I am trying different settings, tires and to manage to stay in the same running line, which was difficult initially and still sounds a bit challenge now. I keep learning.
Now I just bought the Extreme stock esc + team power 9.5T(old version) and will try your suggestion as a start. Thanks again.
