Well I finally received my metal hd input gear that I been waiting on for forever and now my mega can actually handle the new 4 pole brushless motor and upgraded esc I got for it. Well it’s definitely a lot faster. Can really tell the difference in speed and acceleration. Now currently I’m running a venom nimh 8.4v 5000 mah battery. But I keep seeing a lot of talk about running a lipo battery. So for this setup I have now am I better off with the nimh battery or a lipo. Which is fastest and gives you the longer run time. Thanks everyone.
