...which at least confirms that its the spinner energy which is being used for the flipper (rather than a secondary CO2 cylinder like, IIRC, ROTAS).

Interesting, but it puts a lot of force on whichever mechanism is responsible for converting the spin to a flip. Wasnt the theory that you can store more energy in CO2 than in batteries anyway?

Still, itll be interesting to see it run. Its certainly one way to give your flipper some defence...
