I recently did a flipper rebuild and a playfield polish on my roadshow and am NOT liking the results.
The flippers seem super strong now and the ball flies around like a bullet. It hasn't happened yet but
I'm afraid broken plastics are in my near future.
The main suspects now are the flipper coils.
Whoever wrote the manual must have been confused as there are two different coils listed. It says they should be the orange FL15411 (which are installed) but elsewhere it says to use yellow FL11753's. The latter sound a little weak for the main flippers though.

Has anyone ever used them or should I try something in between like the red FL11630's?

Use the manufactures recommendations and go by the number not the color. Did you get the adjustment on the EOS switch right? Sounds like your getting high voltage the entire stroke...

Good advice there from jrrdw... stick with stock configuration and check those EOS switches.

RS is a great game ... a favorite in our house.

This is flitronics so forget your EOS points.

The manufacturers usually used coils too strong for the game. They knew they'd be dirty and not kept up.

Now the collectors usually take better care of their games. New balls, playfield cleaned and waxed. So often you can go a coil size weaker and still get good performance and not break stuff.

FL-11629 (blue) Strongest
FL-15411 (orange)
FL-11630 (red)
FL-11722 (green)
FL-11753 (yellow) Weakest.

Flipper coil strength table...

roadshow is a FlipTronics game. The EOS switches have nothing to do with stroke power. The game will play the same with them forced closed or with them completely missing. Here is a description of how WPC FlipTronics games work...

Your choices are slim...weaker flippers or risky play...

you could try increasing the rear of the playfield by a degree or two

Ok, so I'll order some FL-11630's and see how they do. Thanks for the help!

That would help a little but would speed the ball up going downhill and make the game more
difficult. And with my flipper skills difficulty is not something I need to increase.

So, I got to install the red FL11630 coils last week and they work great. The balls are still easily making it up the far ramps but not moving so fast that my eyes can't track them.
Their power is PLENTY on a well maintained machine.

Thanks for the help, another case closed.

Do you need to do anything to the boards when upping or lowering flipper coil strength?

My guess would be No, because it still pumps the same voltage to the coils. There is just more or less coil windings making it weaker or stronger.

I didn't do anything else, so that seems to be true.
