thanks for the tip. do you know of any trans options for t maxx? i run a 16t bell with 72t spur gear but thats not enough. 2.5 optidrive is a turn lower but still... i want about a 60:1 ratio. stock is around 25:1 i have been told. i run 32 pitch gears now but if i went to .8 metric i might have enough room for a reduction device.
