BetaFlight does not come with a Model for RC Car/Truck. It has to be custom made and adapted from the Airplane Model.
The key points here are:
servo 2 1000 2000 1500 100 2
And you must use servo 2
My RC Car/Truck Config (Example)
Update:
Using a Drone ESC for an RC Car is similar in configuration, but you don’t need to configure it for PWM. I currently have a DYS XSD20A on a RC18MT with surges up to 27A in 3D mode with Active Breaking (Active Breaking is awesome! 🙂 ) The configuration was actually easier. I’m running DSHOT600 and when switching to DSHOT over PWM, the RC truck was faster and more responsive due to the ESC being more “Efficient” at what it does. I HIGHLY Suggest DSHOT over PWM!
