Had this discussion with Bruce from speedmerchant. 2s 21.5 huge in Japan
Me and my race announcer at 360v2 in New York ran 2s 17.5 on spec tires was amazing and controllable power. Be a great 5 min class. Easy on tires. No need for killer cells. Lotta fun
Maybe even a spec locked timing motor. Like a 13.5 hw or something.
