I though I'd make this thread because after two hours of searching I didn't find a true good answer. What would be a good pinion to run on the DeWalt with the stock 68t spur gear? I'm leaning towards a 18t pinion, but I'm not 100% sure. I'll be running 80-90% in grass that sometimes can get rather tall. I'm really afraid the 18t pinion is too high gearing and it will kill run time, or ruin my esc/DeWalt. So, what gearing is everyone using with their DeWalts? I just want to get a feel for what I should use. Thanks!
