Hey,
Im currently running a Factory Team TC4 and i was wondering what a good FDR would be. Im running 13.5 brushless with lipo and the motor is a trinity...also im running rubber tires. Right now my FDR is 4.3 and the car feels a tad bit slow. I am running an 87 spur and 50 pinion. If anyone has any suggestions or input it would be greatly appreciated... thanks
