1st me start off with Happy New year to everyone.


I got a practice tree for Christmas and was wondering how to find out how much roll out does the average track have

Happy New Year to you too...

As for rollout its from when the bulbs are on until one's off...

I try to go up on the starting line before the racing starts and use my foot to activate the pre stage and then the stage lights on both sides and make two marks in the rubber with my pocket knife and look to see how close or wide apart they are off the tip of my shoe
NHRA specs for their sanction races is that the staging bulbs on the starting line are to be one inch off the ground and eleven inches apart center to center. The finish line bulbs are higher

Just roll how much delay that you usually use in the car into the practice tree and find out from there. If you have 0 rollout you will probably go .2-.3 red. Adjust the rollout accordingly.

Typical rollout for a car like shown in your picture....30-.34

X2. I use .32 and it seems good. Add .04 If you have one with incandescent bulbs like the Finish Line II

I use .320, my car leaves mid 1.20-1.30 60ft

Am I wrong about this.....? Rollout has little to do with the lights, as there is an NHRA standard for where they are (there may be slight variances); and everything to do with the diameter of tire on your car, and how your car moves it through the beam.

I feel the best way to use a practice tree is to use it to hone your ability to move your light. I.E.: hit a certain number a few times, say .030, then back it off to .060..... then down to really tight or red, and so-on.

The starting line beams can vary from track to track. Woodburn for example is always about .020 faster than any other track in D6. Obviously the beams there are closer together than some other tracks, but still within spec for NHRA.

Your way of using the practice tree is also not generally advisable for most people. Hit the tree the same every single time, and make adjustments to the car to speed up or slow down reaction time.

OP, depending on the practice tree, you should be in the .320-.340 range.

To be honest, none of that even matters. The number that shows up on your practice tree screen means nothing. You just want it to be consistent. You just want to be able to "hit" the tree consistently and then adjust box accordingly

I agree, consistency is what you are looking for. Also the buttons really suck on those things, it's just not the same as the car unless you go the full simulator route. Same principle for bottom bulb guys, .3 something delay to simulate the rollout.

Thanks everyone I started out at .340 and just been adjusting lower as I go but really wanted baseline to start with

I've used two or three different practice trees in my life, I wouldn't waste my time or money on them I look at practice trees like no motion flight simulators, it ain't real so why confuse your mind by practicing on something that isn't real

Wondering if a couple of guys named biondo or fletcher ever used a practice tree???

Nothing is better than real world racing as practice, but they are far from a waste. They allow you to teach yourself to "react", and nothing more. It made a significant difference for me, so I hope everyone else follows your opinion and throws them in the trash.

Self confidence can be learned by many different ways, practice trees may be one of those that work for you

It's winter time I'm bored besides I got it as a Christmas gift.


I think she giving me hints I need to do better at the track because when I come home early it's a battle for the remote control Lol

You just reminded me to put batteries in mine and get practicing for this season.lol

May want to read all topics

I am thinking Michael Beard may know a little about bracket racing.

Winner and runner up

I guess, but I'd venture to say you'd be hard-pressed to find any serious racer who doesn't have one. You don't get better hitting the tree without practice.

Biggest thing it helped me get over was my nerves engaging when the lights start to come down. Once I saw amber I'd lose focus
