Frequently Asked Questions

What kinds of RC racing does it support?
Any class you run: dirt oval, carpet oval, and off-road. Surface types cover dirt, clay, carpet, and turf, with fields that fit your chassis.
How is this different from RaceNight?
Same idea, built for RC: RacerRX's fields, templates, and AI are tuned for radio-control cars instead of full-size race cars.
Does it work at the track?
Yes. RacerRX logs runs offline right at your pit table. Asking the AI crew chief requires an active connection.
iPhone and Android?
Both. Download from the Apple App Store or Google Play.
How much does RacerRX cost?
RacerRX is $49.99 per year or $4.99 per month, starting with a 14-day free trial. One plan with everything included: unlimited cars, setups, races, and the AI crew chief.
