What a difference this makes. I was using a 14 tooth pinion on a rustler 4x4 with vxl swap on a Nimh and I'll tell you what. Within 5 minutes I ran into my foot with my sneakers on and it ripped off my big toe nail. It's a lot faster with a lipo obviously so be careful, It can get expensive and painful. Happy ripping!
