Please help, i just got my new velineon brushless 3500 system because my old one went up in white smoke, i also just got in my new spc 6000 mah 30c lipo and i was so eager to get back on the road with this puppy, and in 5 minutes it made a weird sound and go figure it was the spur gear completely destroyed, i have all stock gearing, am i supposed to change gearing when i put in a spc 6000mah 30c 2s lipo? i really dont know and im so ticked right now!! Please help me on which gearing to put in please!!! or why it did this?? and also now my lipo is all charged and is going to have to wait about a week to get run again, is that bad for it?
