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. Also, the upgrade will make the machine honor "hole-shot" wins. This means the ET clock will start when the car leaves the line and not when the lights change green. This makes it possible for the car with the slower time to get the win light because a quicker RT more than made up the difference in ET's. All Slot Dragon Systems sold after March 2014 have these features standard.

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.

Upgrade Slot Dragon too SD2

This upgrade will transform any Original Slot Dragon into a SD2 System. Includes new Button Membrane. Added features: Formula One Start Option, Average Lap, Fastest Lap, chimes during race whenever fastest lap is recorded(per car). 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 the possibility of a push-button start.
