i've been using aero tech's grease, but didn't work good, but i just tried nitroblast.com 's grease that i got for my nitro car long time ago, and the loud gear noises are gone!! it might be the extra thick grease making it quiet, but whatever it is it's really great, nowthe tank is alot quieter, seems smoother and goes straighter too, so really thick grease could be the answer
