My girlfriend and I have been bashers now for 6 months. I have a 2x4 slash with stock gearing. I have a 5800kv fuse brushless system. And I normally run around 5000 to 5300 mah 2 cell lipo. The motor seems to run hot most of the time, I do have a fan on the esc. In my opinion my gearing my be a little high. Taking all that in consideration I want to go to my local short course track which is moist hard pack.... I would appreciate any opinion on gearing and tire. Also I have Traxxas Big bore shocks can you recommend oil weight....? thanks so much..
