Slot Dragon Upgrade
This upgrade will add Negative Reaction times in the event of a red-light and a .8 to 1.3 second Random Variable Delay to the Stage Lights that mimics NHRA format exactly. Systems made before April of 2014 had a fixed Stage Light time duration set at .4 seconds. The upgrade will also make the Stage Lights work all the time. This will allow for staging the cars of the next race without resetting the machine from the previous race, essentially making for a push-button start. All Slot Dragon Systems sold after March 2014 have these features standard.
$25

SD2 Upgrade.
This upgrade will add a Formula One Start Option, a .8 to 1.3 second Random Variable Delay to the Stage Lights when using with Christmas Tree, and a thicker button membrane. All SD2's sold after November 2014 will have these features standard.

If your Slot Dragon System was manufactured before April 2014 it will also add Negative reaction Times in the event of a red-light, a .8 to 1.3 Random Variable Delay on the Stage Lights when using the Christmas Tree start option, and Stage Lights will always function allowing the cars to stage before resetting the machine thus creating a push-button start.
