Delay box

Curious about how much delay you set for top bulb racers.

Trial & error until you find what's for you. Play with a practice tree & see where you may start.

when I had my tube chassis car i ran 1.015 in daylight and 1.025 night it depends on how you see the light and car reacts it takes practice in the car and this worked for me.

In theory if you can go .000 on the bottom you would add 1.000. But there is no anticipation on the top bulb. Most cant go .000 off the bottom. Hit the practice tree with the same rollout between full and pro. How much slower are you on pro? I practice a lot. I'm still about .01 slower average on pro. So then you're going to be roughly .950-.990 on a car that works well on a .500 tree to hit a .000. Then add to that how close you want to cut it.
