Don’t do it.

I like it. Just make it easily reversible. In fact, if yer feeling sporty, put a toggle switch under the cab to turn it off and on!

How do you accomplish this, isn’t it software based? Sounds like a good way to burn some coils.

Yeah, it would be a bad idea to do it by just cutting the EOS power to zero. That would make the flipper rapidly flip again and again instead of holding, which is not what you want and would probably harm the mechanisms.

It seems like it could be done with an only slightly more elaborate hardware hack, though... just splice in a little circuit between the flipper button and the upper flipper mechanism, with the behavior "When the flipper button is pressed and power starts being supplied to the upper flipper mechanism, cut the power after 1/4 second, and leave it cut off until the flipper button is released and pressed again."

I have a witness. One time on location I got to rule the universe, but the left flipper wouldn't trap. Might be my best pinball moment.

It was fun, I'd say go for it

It's done on the mpu, but on Devil Riders, the outlanes have a one flip only flipper that activates with the outlane rollover above it. You get one flip and it dies until you drain or relight the rollover.

Dunno if you could do something like that on SoF, but it'd be kewl.
