here are MY hacker preferences for 6T motor and sport ESC=

Timing profile: 1 (5deg)
Don’t screw around with this to much. Using the higher profiles will give you more speed but also really heat up the speedie. I think the hacker 6T is a 2pole motor, so don’t use any more timing then 5deg.

Drive freq profile: 2 (16khz)
I know most of the other guys run 32khz to reduce the lag, but I find 16khz or 8khz to be much smoother and more linear. Maby its because I have the sport speedie with the 6T and it doesn’t handle the higher freq’s well

Current limiter profile: 4 (unlimited)

Rollouts I personally run:
at eastern creek: 22
at northside: 21.5
at mingara: 23.5
at castle hill: 20.8

this is just what i personally run. You will have to find what suits you best
