Not the stock gearing. 25 tooth pinion(not stock) 81 tooth spur (stock).
It jitters off the line.

The temps of the esc and the motor will help to narrow down a safe gearing range for you. Next time you run, get the temps after a few runs. Pay attention to the ambient temp as well. If it's hot out, they tend to run hotter as well. Tracking your gearing and temps after a while will help get you dialed in, dead on!
