I have to disagree with the drag brake. You want the car to roll when the trigger is at neutral, especially in stock. Drive freq can be at 7.xx or5.xx. Deadband at 1% and minimum drive at at least 6% Brake freq turn up to 15.xx or higher. And turn your brake pot all the way anti-clockwise. Do not turn on drag brake, it makes the car inconsistant off power. Some people like it but not a good habit to get into if you want to make A-main.
Monitor the trigger throw of your radio with the pit wizard and adjust end points so that the trigger throws have minimum values as per the pit wizard manual.
