Whatever you do in "widening" the staging area needs to retract to normal width before the start gate opens. Ratraction could be into the guide rail or into the track, and could be linked to the gate release function.

Not going to investigate the feasibility of implementing this, but here's my most recent thought on the subject:

It does limit design possibilities, but: either axle guards or some other standard plate with a center hole. The track would have two pins per lane. The cars would be put on the pins, the pins lowered, the heat run.

Consistent every time.

The design limitations would be:
- enough meat on the bottom to install the plates.
- placement of the plates to allow the least amount of rol forward when the staging pins are lowered.

Clever idea. Such a "plate" could be a required component with location specs relative to the front of the car and the bottom of the wheels! Then, there are no traditional starting pins!

I'm not going to pursue the idea either since I feel that owner/driver staging of the cars "by eye" is preferred. But it would be very useful on the test track!

Well, problem is that whatever determines the starting position of the car needs to determine the finishing position of the car. Hence I figured pins to stage and standard starting gate to control the race.

But here's a cool idea: Breakbeam starting line on each track. Then everyone is released at the same time and timed over the same distance. Possibility of interesting results...

That's my preference too.

But, I'm plodding along trying to design individual lane controls for the starting gate. Put the starting lights to real use. That and the .1 second difference between cars would probably eclipsed by the reaction times of the racers. Giving a "poor" car with a great racer a chance at the title!

Slarty,

The plates are an interesting idea.

I'd be more a fan of something that can be added to the track's starting zone to aid in staging. Something along the lines of Michael Lastufka's staging jig (darn site has exceeded its bandwidth again) mounted to the track. It would serve to space the wheels away from the track (and hopefully away from the axle heads). You would likely need a jig made available at check-in to ensure the cars will not have any fit issues.

Ohhhh!!! Neat idea!

Each racer gets a start button for his own lane! :) Need to electronically avoid false starts and award a small time penalty for pushing the button before the "green light"! The penalty needs to slightly exceed most kid reaction times.

A new dimension in racing! Just gotta make sure that the controls match up to the boys correctly! Wouldn't want Johnny pushing the "GO" button for Bobby's car!

I've heard of a few people building a similar system. The timing starts when the light tree hits green, and if someone trips too early, the red light comes on and the heat rerun. Though, you could interlock it so that an early button press by a racer will not trigger their lane, so they would have to press the button a second time in order to go. That would penalize those racers while not penalizing the others.

Thanks. It's my current obsession.

And with the current infatuation with video games and the development of electronics, I figure it’s the step to bring PWD into the 21st century.

And there are so many possible variables to play with to make the difficulty age and group appropriate.

Simply giving recognition to fast reaction times, giving advantages to being first, disadvantages to being last, register false starts or not, DQ racers after a number of false starts.

The last one I figure is perfect for Open and adult racing. How humiliating to have your car released before or after the hat is run and registering a time that could have otherwise won...

But the price so far is rediculously prohibitive.

THAT would be concern number one!

After a group spends over $1500 for a track and electronics, just how much is "rediculously expensive?" Since it replaces alternative controls, I bet you could get the incremental cost under $40 per lane.

I could see that having a start gate system with one solenoid per lane could be costly. If you use the green light signal to trigger the timer start, you can use an available timer. You, of course, would need a light tree that you can interface with. You'd be surprised at what people are willing to plunk out for a full "state of the art" setup.

Color coding the trigger switches and lanes would help.

I think this is a neat idea. But it would need to have two modes:

1. Individual buttons for each lane.

2. Master button to trigger all lanes simultaneously - for younger kids, or for races in which individual triggering is not desired.

Already ahead of you.

Actually, 3 modes:

3. One button for individual starts.

Each racer stages their car and proceeds to the launch button. That racer is given a starting countdown, reaction time is stored. Other racers are staging while this is going on.

All racers go to finish, heat is started with each car delayed by the recorded reaction time.

Thought of that because of the inordinate amount of time racer staging and execution of individual lane starting might take.

That would really seem to over complicate things and eliminate the excitement of triggering individually when the light hits green.

I can see having a master switch to trigger all lanes, like Randy D. recommended, because there are situations where individual triggering would not be desired.

Here's the picture of Michael's "Racer Spacer" jig that I mentioned. When his site is up, you can find the info on it at http://www.lastufka.net/lab/cars/html/fork.htm.

They already have this kind of drag strip type track and start mechanism for Hot Wheels cars. Check out: http://www.dragmasters.net/
