Punch control on the Mamba line of controllers is basically a spool up timer. The higher the setting, the longer it will take the motor to spool up to its top speed. It wont spin any slower, it will just take longer to get there.
You are still going to need to use some throttle control when driving. punch control is one thing for taking away the hard edge of the power, but if you use it to totally remove any chance of flipping the truck, you will be taking away the acceleration rate throuout the whole curve. Ya just gotta learn to drive it.
As far as what others set theirs at is really irelevant. Every motor, battery, and gearing combo is going to change how the punch controll setting feels. Just find the setting that feels good to you and go with it.
In my track buggy I actually run 70% because it gives me better controll and faster for consitent lap times, but in my bashers I run wide open 0% punch control. Just controll your finger.
