Need help with gearing.
 

I've got an 8XL motor running on 14 3300 cells. The torque is great, and the top speed isn't. It seems to be just as fast as a stock emaxx on 14 cells.

My gearing is 66/18. thanks

I don't think its your gearing. It might be your radio. Have you checked your epa?

I found problem. It was user erorr. I locked the trans in 1st instead of 2nd. I've never owned a stock e-maxx to know how the trans actually works.

Ah, that would explain the problem.
