Not sure where exactly to post this question but I am brand new to the R/C world and I have bought a stampede 4x4 with the 12t motor and am wondering what kind of upgrades I can add to it to make it a bit stronger. I live in an area that has loose/hard dirt, gravel, grass and rock's of all sizes. I have been using it for roughly 12 hours since yesterday. I do not like how long the battery lasts, at most 20 minutes I was hoping to get something more along the lines of 60+ minutes on one single charge of use. I would like a battery that can live up to what I want I am not worried about the price of the battery as long as its not over 150 dollars.
