hey guys, i have started building a small track in the woods for my 2wd slash. it has your typical bumps, turns, mud, water creeks(no deeper then the truck), inclines and jumps. its a tight track with loose dirt, damp, mud, and packed dirt. the truck is all stock except the bigger 7 cell. the gearing is 19/90. i want more low top end for quick acceleration off corners but still have some top end on short straight aways. might change the pinion to 16 tooth and keep the 90 tooth spur. right now its got your basic traxxas slash tires that are worn almost to slicks. might run some trenchers 2.2. also how can i improve the turning radius? i need more practice before i go with the brushless CC sw3 combo. anyways let me know what you think for proper gearing and treads. thanks.
