    put a bigger pinion, as in more teeth for more top speed.

    go to a bigger pinon robinson racing makes a light 25 tooth pion and then put a 69 tooth spur that coems with a tc3 that will make it scoot at a 2:1 ratio PROBLEM IS you might not have much run time, things might get hot, I had that set up in my 4tec and it I got #@$% ty run time so I put a 78 tooth spur on and I get same speed and longer run time. Its kinda like you gotta find the sweet spot of your motor. What kind of motor is in it. Also for a few bucks get soem no loss connectors they make a big difference and keep the heat down, and there sheap and good to use if your running a hotter motor or high gearing/larger batts.

    hmmm try going down to a 15 turn motor if your esc car handle it. Also try around a 80 tooth spur and a 30 tooth pinon.
