Where is a good place to start for my gear ratio? My car came with a 48P/87T spur gear. I am going to be running 17.5 blinky mode, indoors on carpet. We use 26mm foam tires all the way around the car. My motor is currently a Turnigy Track Star 17.5. ESC is a 60A Turnigy Track Star. I just ordered a Brushless Hobbies LT4 80A ESC to give that a try. I have no issues changing out the spur gear. I just need to figure out where a good place is to start my gear ratio and I can probably figure out the gearing from there. Thanks!
