this is a set up i still run to this day....our tracks over here are the same as you run on dusty and grippy....

run x 2000s version 2 red great rear tyre .............. also try losi BK bars or the new AKA rebars they are very good!!!!!!!

calibers are the worst tyre ive ever used!!!!!!!!!!!

going by your ratio u run no boost...... so try running 69/ 37 for 17.5 if the temp of the motor comes of under 70 after 6 mins keep running it!!!

we run no timing/boost over here i run 67/37 on a team powers motor and it fly s

you can find picks of my cars on the rctech x factory thread just go back a couple of pages and you can see my last big win!!!...
