Rack speed

[bb21069]

Blue front rocket. I have a 3 3/4". Rocket set up says 4" Thinking about switching to a 4 1/4" or maybe faster. What is everyone else doing? What is everyone running for servos?

basically most people run what ever is comfortable for them,we use a fast rack for short tracks and a slower one for tracks that you dont turn as much(or need steering in put)just keep in mind with a fast rack if you move your hands very much down the straightaway the car will scrub off speed

I used to use a 4.... I switched the pinion myself to a 4 1/2. I use a 220 servo. I love the faster rack, you don't have to counter steer near as much on tight tracks.
