Ummm, REALLY tall. Honestly, you don't need to worry much about a "safe" gearing if you're suing the sintered rotor, I've used some pretty extreme gearings & seen others(including Bob Novak himself) use some INSANE ratios & the motor just keeps chugging along nicely, pulls like a freight train(& I'm talking about FDR's of 3.9:1 with rubber tires at the Novak Race, but I don't know exactly what rollout that equates to, just know the motor can take almost ANYTHING you can dish out).....
