Sorry I have no kit. I used an old Air Hogs 2-channel micro rc helicopter. I think it costs like 20 bucks at Target or Walmart. I simply disconnected the wires from the prop motor and connected it to a 5v DC power supply (wal-wart) and a resistor to drop the voltage a bit (since the motor should run 3.7v DC I think?). The circuit is broken by a 5v relay. I have a rectifier in circuit with the 5v relay which is connected directly to the flasher bulb socket on the left side of the playfield (the flasher that goes off when a ramp shot is made). These quick pulses from the flasher circuit close the relay, and complete the 5v DC circuit tothe props to make them spin.
The subway car is just an HO-scale train car I found on eBay. I inserted a few pinball LED's inside the train car and wired it up to the red spinner LED circuit so the lights blink in conjunction with the spinner led's. I used four #555 style LED’s inside the train car. Three of them are connected to the GI circuit and always keep the car lit. The fourth is the headlight on the front of the train that is connected to the “super spin” sign’s light, so it’s interactive and blinks with gameplay. I used JST style connectors coming out of the rear of the train car to connect it to the rest of the wiring so it’d be easier to install and/or remove. The bottom of the train car has been removed. The #555 lights are glued into the track (see photo) and wired from underneath, soldered, and adhered with hot glue. I used twist-ties to mount the train car to the track.
I use the service AC outlet with a surge protector inside the machine to plug in a 12 dc adapter (wall wart) and a usb charger port that handles all of the power for the 12v led strips, stop light, and playfield police flasher.
The playfield police flasher is simply a cheap-o party flasher I found on ebay for like $10. I soldered wires on the flasher's battery leads and ran it to my 5v supply. Only additional thing i did was added a 12 relay to the circuit that powers the topper police flasher. When this circuit is activated it also closes the relay which turns on the separate 5v circuit to the playfield police flasher so they both go on and off at the same time.
the car in my machine is not connected to a flasher. It is connected to the red light above the right spinner. I took the car apart, drilled holes and mounted LED's for the headlights and blue police light on top of the car. All of the led's in the car are hooked to one of those JST connectors coming out of the back of the car, then from there to the spinner light. The playfield lights are 6.3V which is way too much voltage for a standalone LED so I placed some resistors inside the car to drop the voltage so the brightness was about where i wanted it. Not very scientific but it works. I just experimented with some resistors till I got the led's to dim a bit so i knew i wasn't over-volting them. Car is 1/18 scale I think.
I put the stop light in the back left corner, I mounted it with adhesive velcro strips to the playfield plastic. Not sure what the led strips were called, I found them years ago at Walmart in the automotive interior lighting Isle. I don't see the exact ones on ebay either. Maybe discontinued. There's a bunch of similar 12v led strips and neon tubes on ebay that'd work though and look very similar. Might want to play with some resistors or use less than 12v since those can be blindingly bright.
If you have any other specific questions please feel free to ask and I'll try to answer them. I think I added some more descriptions and explanations in the Youtube video description as well. Good luck!
