We Raced for 6 min in Mod at my area track at the some time which seriously should have been 5 min. So with only 1200 mah batteries in 4wd it was tough never to dump. So I attempted all motors and gearing for being on speed & not dumping. https://vintage-le-mans-racing-pr67890.gynoblog.com/34024249/examine-this-report-on-le-mans-race-track-art
