As a rookie you will need to start in F2. You can start in F1 if you qualify by meeting a predetermined qualifying time. The website provides information on the rules for each class. The difference between classes has to do with motor speed and tire choices. Races last for 15mins and you will need to do two pit stops. You will need to run a rwd f1 chassis. People run Tamiya’s Trf103 , Xray x1, roche evo, Capricorn f1, exotek f1r3, etc. Contact Tony Phalen...great guy. All info available on the website.
